Abstract：
UNASSIGNED: Launaea cornuta is a vegetable with therapeutic advantage for human diseases.
UNASSIGNED: Evaluate nutritive and non-nutritive components, antioxidant activity, and Fourier transform infrared spectroscopy profile of L. cornuta leaves.
UNASSIGNED: Proximate, nutri, non-nutrient, percentage phenolic, flavonoid, alkaloid, and saponin contents were investigated using standard procedures. Total phenolic and flavonoids of the extracts were determined spectroscopically. Antioxidant activity and functional groups in the extracts were characterised by 2.2- diphenyl-2-picryl-hydrazyl radical and FTIR spectroscopy, respectively.
UNASSIGNED: Carbohydrates were the most abundant (57.61±0.61 %), and crude lipids were the least abundant (4.26±0.20 %) in L. cornuta. Essential amino acids were present in varying concentrations, and histidine was the most abundant (251.20±2.00 mg/100 g dw). Calcium was the most abundant mineral element (820.49±1.05 µg/g dw). High concentrations of phenols (13.07±0.60 %) and low amounts of saponins (2.19±0.10 %) were recorded. Methanolic and aqueous leaf extracts revealed total phenols of 83.10±4.32 and 57.77 ±1.65 mgGAE/g dw, respectively, while total flavonoids were 8.00±0.01 and 7.99±0.03 mgCE/g of dry weight, respectively. Aqueous extract had significant DPPH radical scavenging efficacy (IC50 =72.96± 0.32 µg/ml) compared to 681.57± 2.21 jg/ml for methanol extract.
UNASSIGNED: L. cornuta contain phytochemicals with health benefits for averting oxidative stress related diseases.

摘要：
■Launaeacornuta是一种对人类疾病具有治疗优势的蔬菜。
■评估营养成分和非营养成分，抗氧化活性，和L.cornuta叶的傅里叶变换红外光谱图。
■接近，Nutri,非营养，酚醛百分比，类黄酮，生物碱,使用标准程序研究皂苷含量。通过光谱测定提取物的总酚和类黄酮。提取物中的抗氧化活性和官能团通过2.2-二苯基-2-甲基酰基-肼基自由基和FTIR光谱进行表征，分别。
■碳水化合物含量最高（57.61±0.61％），在玉米乳杆菌中，粗脂含量最低(4.26±0.20%)。必需氨基酸以不同的浓度存在，组氨酸含量最高(251.20±2.00mg/100gdw)。钙是最丰富的矿物元素（820.49±1.05µg/gdw）。记录到高浓度的酚（13.07±0.60％）和少量的皂苷（2.19±0.10％）。甲醇和水性叶提取物显示总酚为83.10±4.32和57.77±1.65mgGAE/gdw，分别,而总黄酮为干重的8.00±0.01和7.99±0.03mgCE/g，分别。水提取物具有显着的DPPH自由基清除功效（IC50=72.96±0.32µg/ml），而甲醇提取物为681.57±2.21jg/ml。
■L.cornuta含有植物化学物质，对避免氧化应激相关疾病具有健康益处。
