Cumin seeds are frequently utilized in herbal infusions and as flavoring agents in home cuisine. Nevertheless, studies have demonstrated that spices are frequently contaminated with pathogenic bacteria, including bacterial spores. The aim of this study was to assess the effectiveness of a new decontamination method called \"Intensification of Vaporization by Decompression to the Vacuum\" (IVDV) on intentionally contaminated Cuminum cyminum seeds. The study also examined the impact of this treatment on the color and oil profile of the treated samples. The untreated samples were inoculated with Escherichia coli (ATCC 25922) and Salmonella Typhimurium (ATCC 14028) and then subjected to IVDV treatment. Response surface methodology was employed to obtain safe, high-quality cumin seeds presenting a balance between microbial load, color, and oil profile. The optimal IVDV conditions were achieved at a pressure of 3.5 bar and a time of 133.45 s, resulting in typical 4 log reductions observed with 99.99% of Escherichia coli and Salmonella Typhimurium inactivation. The treated spices presented a mild color modification compared to the untreated ones, manifested by a darker shade (decreased L* value), reduced greenness (increased a* value), and heightened yellowness (increased b* value). The GC-MS analysis detected the existence of seven compounds in the treated cumin, with cuminaldehyde being the primary compound (83.79%). Furthermore, the use of IVDV treatment resulted in an increase in the total content of essential oils in some samples, whereby six monoterpenes were identified in the untreated sample compared to seven monoterpenes in IVDV-treated samples. This innovative technology demonstrated high efficacy in decontaminating C. cyminum seeds, improving the extractability of the essential oils while only slightly affecting the color.

OBJECTIVE: Considering the significant prevalence of ileus after abdominal surgery and the beneficial effects of Cuminum cyminum in digestive problems, this study aimed to examine whether Cuminum cyminum has any effect on the return of bowel motility after abdominal surgery.
METHODS: In this triple-blind clinical trial study, 74 patients undergoing abdominal surgery were assigned to the intervention and control groups using minimization methods. The patients in the intervention group consumed 250 mg capsules containing Cuminum cyminum extract 4 h after the surgery and another dose of the drug 1 h afterward. The patients in the control group consumed a 250 mg capsule containing starch as a placebo at hours similar to those in the intervention group. The instruments used to collect the data were a demographic questionnaire and a researcher-made checklist to assess bowel habits. The data were analyzed using SPSS-22 software.
RESULTS: The average time of gas passing in the intervention and control groups was 9.03 ± 3.41 and 11.72 ± 4.21 h, respectively. The defecation times in the intervention and control groups were 16.97 ± 5.02 and 26 ± 9.87 h, showing a significant difference between the two groups as indicated by the independent samples T-test (P > 0.001). Furthermore, abdominal pain, abdominal bloating, nausea, and vomiting were significantly less frequent in the intervention group compared to the control group as confirmed by Fisher\'s exact test (P > 0.001).
CONCLUSIONS: According to the results, the consumption of Cuminum cyminum after abdominal surgery helps to reduce the time of gas passing, defecation, and the return of bowel motility. However, additional studies need to address the effectiveness of Cuminum cyminum by changing the time and duration of its use.

UNASSIGNED: Naringenin based nanocomposite alleviate the harmful effects of drought stress in Cuminum cyminum and enhance carefully the plant tolerance against drought condition with different mechanisms.
UNASSIGNED: In the recent years, drought stress is considered as one of the most important stressful conditions for agricultural plants. Reducing the effects of drought on plants is a crucial need nowadays, which calls for innovative methods. Naringenin is one of the most known plant flavonoids with antioxidant properties. In the present work, a naringenin based nanocomposite containing carboxymethylcellulose (CMC) as carrier (CMC-Nar) with an average size of 65 nm were synthesized by coacervation method. In order to investigate the effect of CMC nanocomposites containing naringenin (CMC-Nar) and pure naringenin in modulating the effects of drought stress, cultivation of Cuminum cyminum (varieties: Isfahan and Kashan) was carried out in greenhouse conditions. Drought stress was imposed as 30% of the field capacity. Various physiological, biochemical, and phytochemical assays were performed after treating the plants in drought conditions (30%). The results indicated that treatment of nanocomposites (CMC-Nar) and pure naringenin at drought conditions increased growth and photosynthetic parameters such as germination, shoot and root fresh weight, shoot dry weight, and chlorophyll content of the Cumin. Stress markers such as malondialdehyde, H2O2, and electrolyte leakage decreased under the treatment of narinjenin and especially nanocomposites (CMC-Nar) under drought conditions. Moreover, under same condition and treatments, some biochemical parameters including soluble sugar and total protein increased but the activity of antioxidant enzymes and the level of free amino acids has gone down. Compatible Solutes (Proline and glycine betaine) also increased. There was an increase in phytochemical parameters such as total phenols, flavonoids, anthocyanin, and tannins under naringenin and nanocomposites (CMC-Nar) treatment in drought conditions. In general, nanocomposites and pure naringenin reduced the harmful effects of drought stress, and the ameliorating impacts of nanocomposites (CMC-Nar) are more than pure naringenin. According to the results: In most cases, the impact of drought stress was modulated to a greater extent by (CMC-Nar) nanocomposites in the Isfahan variety compared to the Kashan variety. This research tries to propose a new method to reduce the effects of drought stress on Cuminum cyminum.

(1) Background: Cumin seeds, extracted from the plant Cuminum cyminum, are abundant in phenolic compounds and have been extensively researched for their chemical makeup and biological effects. The objective of this research is to enhance the water extraction of polyphenols through the water bath (WB) technique and to evaluate the antiradical, antibacterial, and anticancer effects of the extract. (2) Methods: Response Surface Methodology was used to find the best parameters to extract polyphenols. Three experimental parameters, time, temperature, and solid-liquid ratio, were tested. The disc diffusion method has been used to determine the antimicrobial activities against Salmonella Typhimurium, Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, and Candida albicans. The antiradical activity was performed using the DPPH method, while total phenolic content was performed using Folin-Ciocalteu. High-Performance Liquid Chromatography (HPLC) was conducted to analyze the phytochemical profile of WB extracts. The anticancer activity of the lyophilized extract was assessed against three cancer cell lines (colon (HT29), lung (A549), and breast (MCF7) cancer cell lines).; (3) Results: The optimal conditions for water extraction were 130 min at 72 °C. The total phenolic compounds yield (14.7 mg GAE/g DM) and antioxidant activity (0.52 mg trolox eq./mL) were obtained using a 1:40 solid-liquid ratio. The primary polyphenols identified were the flavonoids rutin (0.1 ppm) and ellagic acid (3.78 ppm). The extract had no antibacterial or antifungal activities against the microorganisms tested. The extract showed anticancer activity of about 98% against MCF7 (breast cancer cell line), about 81% against HT29 (colon cancer cell line), and 85% against A549 (lung cancer cell line) at high doses. (4) Conclusions: Extraction time and a high solid-liquid ratio had a positive impact on polyphenol recovery and in maintaining their quantity and quality. Furthermore, the optimal aqueous extract exhibited strong antiradical activity reflected by the inhibition of free radicals in addition to a significant specificity against the tested cancer cell lines.

Interstitial Cystitis (IC) is a chronic inflammatory disease that lacks effective treatment. The present study aimed to investigate the potential of aqueous ethanol extract of Cuminum cyminum (AEECC) on oxidative stress, inflammation and overactivity of urinary bladder induced by cyclophosphamide (CYP). Female Sprague-Dawley rats received intraperitoneal administration of cyclophosphamide (150 mg/kg, i. p. 1st , 4th , and 7th days). To investigate the urothelial damage, the bladder weight, nociception behavior, and Evans blue dye extravasation method was used. The antioxidants CAT, GPX and NO were measured. ELISA determined the IL-6 and TNF-α levels. The spasmolytic effect of AEECC was investigated on isolated bladder strips and its mechanisms were determined. The enhanced nociception behavior, bladder weight, vascular permeability, edema, hemorrhage, nitric oxide, IL-6 and TNF-α levels by CYP administration were significantly reduced by AEECC (250 and 500 mg/kg). A significant increase in serum antioxidant system such as CAT and GPx was also observed in AEECC-treated rats. The AEECC (3 mg/ml) significantly reduced urinary bladder tone in the strips pre-contracted with carbachol in both control and CYP-treated rats. This relaxation was demolished by atropine, nifedipine, glibenclamide, and indomethacin but not with propranolol. The plant extract showed the presence of antioxidant and anti-inflammatory phytochemicals. These results suggest that Cuminum cyminum offers uroprotective activity and can ameliorate CYP-induced bladder toxicity by modulating antioxidant parameters, pro-inflammatory cytokine levels and bladder smooth muscle overactivity. The in silico binding interactions of antioxidant 2I3Y and anti-inflammatory protein 1TNF with various ligands from Cuminum cyminum seeds revealed potential bioactive compounds with promising antioxidant and anti-inflammatory properties, providing valuable insights for drug development and nutraceutical research.

Cumin (Cuminum cyminum L). belongs to the family Apiaceae and the order Apiales, which is a widely grown spice and medicinal plant in Xinjiang province, China. In the current study, whole genome sequencing of C. cyminum was performed using the Illumina HiSeq 4000 platform, and the complete mitogenome sequence was assembled and annotated. We found that the single circular mitogenome of C. cyminum was 246,721 bp in length, and has about 45.5% GC content. It comprised 73 genes in the coding region (35 protein-coding genes, 18 tRNA genes, 3 rRNA genes, and 15 open-reading frames) and a non-coding region. Phylogenetic analysis indicated that C. cyminum is closely related to Daucus carota and the subtribes Daucinae. The mitogenome of C. cyminum revealed its phylogenetic relationships with other species in the Apiaceae family, which would further help in understanding its evolution.

Fasciola hepatica, the liver trematode, infects ruminants and causes economic loss. Because parasites are developing resistance to commercial drugs, the negative effects of parasitism are increasing. In this study, we aimed to evaluate the efficacy of cumin (Cuminum cyminum) essential oil against F. hepatica eggs and adults. The eggs were incubated with eight concentrations of the essential oil (0.031125-4.15 mg/mL), and viable eggs were counted after 14 days and classified as embryonated or non-embryonated. Adult flukes were incubated in Roswell Park Memorial Institute medium to ensure their viability and then incubated in essential oil. They were observed for 24 h after treatment. The adults were assessed with the two lowest effective oil concentrations used in the ovicidal test. Three controls were used for both tests: nitroxynil, a negative control, and Tween®80. After incubation in oil, the adult specimens were processed for histological analysis and stained with hematoxylin-eosin. In addition, the oil was tested for cytotoxicity using Madin-Darby bovine kidney cells to assess any possible effect on them. The oil was effective in ovicidal and adulticidal inhibition of the trematode, with statistically significant results. All concentrations assessed in the ovicidal test were 100% effective. The adult test was effective within 15 h and inactivated all the specimens at the highest concentration evaluated (0.06225 mg/mL). Histological analysis showed that cumin essential oil resulted in marked areas of vacuolization. The spines showed no structural changes but were surrounded by microvesicles. These findings indicated that cumin oil could be a potential compound in the control of fasciolosis.

The pharmacological properties of plants lie in the content of secondary metabolites that are classified into different categories based on their biosynthesis, structures, and functions. MicroRNAs (miRNAs) are small non-coding RNA molecules that play crucial post-transcriptional regulatory roles in plants, including development and stress-response signaling; however, information about their involvement in secondary metabolism is still limited. Cumin is one of the most popular seeds from the plant Cuminum cyminum, with extensive applications in herbal medicine and cooking; nevertheless, no previous studies focus on the miRNA profile of cumin. In this study, the miRNA profile of C. cyminum and its association with the biosynthesis of secondary metabolites were determined using NGS technology. The sequencing data yielded 10,956,054 distinct reads with lengths ranging from 16 to 40 nt, of which 349 miRNAs were found to be conserved and 39 to be novel miRNAs. Moreover, this work identified 1959 potential target genes for C. cyminum miRNAs. It is interesting to note that several conserved and novel miRNAs have been found to specifically target important terpenoid backbone, flavonoid biosynthesis, and lipid/fatty acid pathways enzymes. We believe this investigation will aid in elucidating the implications of miRNAs in plant secondary metabolism.

The occurrence of pharmaceutical pollutants in aqueous media has increased where significant research is being conducted to eliminate these toxic compounds. In the present study, Tetradecyltrimethylammonium bromide (TTAB) modified Cuminum cyminum agri-waste (CCW) was prepared to investigate the removal of diclofenac sodium (DCF) from aqueous solution in the batch process for the first time. Physical and chemical characterizations of as-prepared adsorbent were conducted using field emission scanning electron microscopy, Fourier-transform infrared spectroscopy, N2 adsorption-desorption, and point of zero charge analysis. Besides, the effect of the main parameters that affect the adsorption process, i.e., adsorbent dosage (0.25-6 g/L), contact time (0-300 min), initial DCF concentration (10-500 mg/L), and pH of the solution, were investigated. Furthermore, the resulted data were analyzed using various kinetic and isotherm models. The Pseudo-second-order model with R2 = 0.9981 showed the highest agreement with kinetic behavior. Also, the maximum adsorption capacity of DCF is 93.65 mg/g, according to the Langmuir isotherm. In acidic media, the adsorption capacity reached the highest value (44.69 mg/g). As a result, this study revealed that the agri-waste material could be modified and, as a low-cost adsorbent, have promising adsorption potential to remove pharmaceutical contaminants from the aqueous solution.
In this study, an innovative agricultural waste, Cuminum cyminum, has been used as low-cost material and modified with Tetradecyltrimethylammonium bromide cationic surfactant to remove diclofenac sodium (DCF) from aqueous solution in the batch process for the first time. TTAB-modified CCW exhibited an excellent adsorption capacity of 93.65 mg/g. Kinetic and equilibrium investigations were conducted with various models in detail.

BACKGROUND: Numerous herbs are reported to have anti-hyperglycemic activity and are frequently used in combination with prescription drugs to lower the blood glucose levels in diabetic patients, without proper knowledge about the possibility of herb-drug interaction.
OBJECTIVE: To investigate the effect of cumin and garden cress on pharmacokinetics (PK) and pharmacodynamics (PD) of gliclazide (GLZ) in nicotinamide-streptozotocin diabetic model.
METHODS: Diabetic animals of groups II-IV were treated with GLZ, cumin, \'cumin + GLZ\', garden cress and \'garden cress + GLZ\'. Herb\'s treatments were given for two weeks, and GLZ was administered in a single dose. Blood glucose levels (BGLs) were measured at pre-determined time points. Plasma samples of pharmacokinetic study were analyzed using UPLC-MS/MS. GLZ fragment at m/z 324.1>127 was monitored.
RESULTS: Cumin and garden cress have shown 15.3% and 15.9% reduction in mean BGL (1-24h) (p-value < 0.001), respectively. GLZ reduced mean BGL by 30.0%, which was significantly better than cumin and garden cress (pvalue <0.05). Concurrently administered \"garden cress + GLZ\" demonstrated the highest reduction in mean BGL (by 40.46%) and showed a prolonged effect. There was no significant advantage of simultaneously administered \'cumin + GLZ\'. Cumin did not affect PK of GLZ. Garden cress has significantly enhanced AUC0-t (by 69.8%, pvalue 0.0013), but other PK parameters Cmax, Tmax, and Kel were close to the control group.
CONCLUSIONS: PK/PD-based herb-drug interaction was observed. Concurrently administered garden cress + GLZ showed improved antidiabetic effect and has enhanced GLZ bioavailability.
