■PhylanodifloraL.是一种多年生草本植物,属于马鞭草科。它被广泛用作治疗许多疾病的草药饮料。它有抗氧化剂,抗真菌和抗炎特性。在传统医学中,用于治疗皮肤感染。然而,关于有机植物提取物的化学成分的信息很少。因此,这项研究的目的是确定植物有机提取物的化学成分。
■在这项研究中,使用连续索氏提取器和四种不同的溶剂制备有机提取物,这些溶剂的极性从非极性溶剂增加到极性溶剂(石油醚,氯仿,乙酸乙酯,和异丙醇),以确保提取各种化合物的可能性。进行GC-MS分析以确定有机提取物的化学成分。
■在石油醚(Et)提取物中鉴定出19种化合物,14在氯仿(Ch)提取物中,18在乙酸乙酯(Ea)提取物中,15在异丙醇(Is)提取物中。Et提取物中最重要的化合物是1,1-二乙氧基乙烷(33.9%)和十九烷(19.9%)。Ch提取物中最重要的化合物是八烷(37.4%)。Ea提取物中最重要的化合物是3-羟基十二烷酸(17.7%)和异戊酸香叶酯(15.5%)。Is提取物中最重要的化合物是二十二烷酸醇(18.6%)。主要化合物的化学结构通过研究其碎裂机理并将所得片段的分子量与每个质谱中存在的峰的分子量进行比较而通过质谱确认。
■这项研究的结果表明,非极性提取物(石油醚和氯仿)中的主要化合物是碳氢化合物,醚,环氧化物,和硅化合物,虽然中等极性提取物(乙酸乙酯和异丙醇)中的主要化合物是醇,羰基化合物,和含氧萜烯。
UNASSIGNED: Phyla nodiflora L. is a perennial herbaceous plant belonging to the Verbenaceae family. It is widely used as an herbal drink to treat many diseases. It has antioxidant, antifungal and anti-inflammatory properties. In traditional medicine, it is used to treat skin infections. However, there is little information on the chemical composition of organic plant extracts. Therefore, the aim of this study was to determine the chemical composition of organic extracts of P. nodiflora L.
UNASSIGNED: In this study, organic extracts were prepared using a continuous Soxhlet extractor and four different solvents with increasing polarity from nonpolar to polar solvents (petroleum ether, chloroform, ethyl acetate, and isopropanol) to ensure the possibility of extracting a wide range of compounds. GC‒MS analysis was performed to determine the chemical constituents of the organic extracts.
UNASSIGNED: Nineteen compounds were identified in the petroleum ether (Et) extract, 14 in the chloroform (Ch) extract, 18 in the ethyl acetate (Ea) extract and 15 in the isopropanol (Is) extract. The most important compounds in the Et extract were 1,1-diethoxyethane (33.9 %) and nonadecane (19.9 %). The most important compound in the Ch extract was octacosane (37.4 %). The most important compounds in the Ea extract were 3-hydroxy-dodecanoic acid (17.7 %) and geranyl isovalerate (15.5 %). The most important compound in the Is extract was behenic acid alcohol (18.6 %). The chemical structures of the major compounds were confirmed by mass spectrometry by studying their fragmentation mechanism and comparing the molecular weights of the resulting fragments with the molecular weights of the peaks present in each mass spectrum.
UNASSIGNED: The results of this study show that the dominant compounds in nonpolar extracts (petroleum ether and chloroform) are hydrocarbons, ethers, epoxides, and silicon compounds, while the dominant compounds in moderately polar extracts (ethyl acetate and isopropanol) are alcohols, carbonyl compounds, and oxygenated terpenes.
