Abstract

The study was conducted to test the antifungal efficacy of J. curcas leaf extracts against Phaeoisariopsis personata (causal pathogen for groundnut late leaf spot disease) under in vivo conditions, and to identify important phytochemical constituents exhibiting antifungal properties. The results showed that the greatest reduction of late leaf spot disease incidence was achieved by all the Jatropha curcas leaf extracts at the highest concentration (0.5 mg mL-1) as 36.89, 36.59 and 24.67% for chloroform, ethyl acetate and methanolic extracts, respectively. Subsequently, J. curcas leaf extracts treatments enhanced the growth and yield of groundnut compared with the control (untreated). The antifungal effects of J. curcas were supported by the presence of phytochemical constituents identified by GC-MS. Hexadecane; n-hexadecanoic acid; phenol, 2, 4 bis (-dimethylethyl); phytol and hexadecanoic methyl ester were detected as major phytocompounds in J. curcas leaf extracts that were possibly responsible for the antifungal activity. © 2021 Friends Science Publishers

温室条件下对风油草的抗菌作用及麻疯树叶提取物的植物化学分析

在体内条件下，研究了麻瓜叶提取物对花生晚叶斑病病原菌Phaeoisariopsis personata的抗真菌作用，并鉴定了具有抗真菌作用的重要植物化学成分。结果表明，所有麻疯树叶提取物在最高浓度(0.5 mg mL-1)下，氯仿、乙酸乙酯和甲醇提取物分别降低了36.89%、36.59%和24.67%的晚叶斑病发病率。结果表明，与对照(未处理)相比，麻瓜叶提取物处理促进了花生的生长和产量。气相色谱-质谱法鉴定了麻瓜的植物化学成分，证实了麻瓜的抗真菌作用。十六烷;棕榈酸;苯酚，2,4双(-二甲基乙基);结果表明，蓖麻叶提取物中主要含有叶绿醇和十六烷甲酯，可能与抗真菌活性有关。©2021朋友科学出版社
