Twenty-four phenolic compounds including daidzein, epicatechin and artepillin C were identified in Passiflora leschenaultii DC. fruit by UHPLC-QqQ-MS/MS analysis. The aroma profile has been studied using the HS–SPME/GC–MS which revealed 67 volatile compounds including 13 terpenes, 18 alcoholics, 15 esters, ketones and phenolic acids. Further, the proximate composition, anti-radical and anti-diabetic activities of fruit pulp were also determined. The fresh fruit pulp of P. leschenaultii registered higher total phenolic (691.90 mg GAE/g extract) and tannin (313.81 mg GAE/g extract) contents and it also exhibited very high DPPH^• (IC₅₀ of 6.69 µg/ml) and ABTS^+• (9760.44 µM trolox equivalent/g extract) scavenging activities. The fresh fruit pulp showed a strong inhibition towards the α-Amylase and α-Glucosidase (IC₅₀ of 32.20 and 19.81 µg/mL, respectively) enzymes. Thus, the work stipulates that phenolic compounds rich P. leschenaultii fruit can serve as a potential nutraceutical, antioxidative and anti-diabetic agent in food and pharmaceutical formulations.

二十四酚类化合物包括黄豆苷原，表儿茶素和artepillin C下在鉴定西番莲leschenaultii DC。水果通过UHPLC-QqQ-MS / MS分析。使用HS-SPME / GC-MS对香气特征进行了研究，结果发现67种挥发性化合物，包括13种萜烯，18种酒类，15种酯，酮和酚酸。此外，还确定了果肉的近成分，抗自由基和抗糖尿病活性。P. leschenaultii的新鲜果肉中总酚含量（691.90 mg GAE / g提取物）和单宁（313.81 mg GAE / g提取物）含量较高，并且还显示出很高的DPPH ^•（IC ₅₀为6.69 µg / ml）和ABTS ^+•（9760.44 µM trolox当量/克提取物）清除活性。新鲜的果肉显示朝向强烈抑制α淀粉酶和α葡萄糖苷酶（IC ₅₀ 32.20 19.81和微克/毫升，分别地）的酶。因此，这项工作规定，富含酚类化合物的P. leschenaultii水果可以在食品和药物制剂中用作潜在的营养保健品，抗氧化剂和抗糖尿病药。
