In this study, the antifungal, antioxidant, enzyme inhibitory (α-amylase), phytochemical and cytotoxicity profile of Jatropha curcas seed oil and de-oiled seed cake extracts was determined. The antifungal activities were investigated against different phytopathogenic fungi including Colletotrichum coccodes, Pythium ultimum, Phytophthora capsici, Rhizoctonia solani, Bipolaris oryzae and Fusarium fujikuroi. Methanolic extract was found to be highly fungicidal as compared to aqueous extract, n-hexane extract and seed oil, against P. capsici and F. fujikuroi. Methanolic extract was also found to possess significantly higher antioxidant potential (p < 0.05) than the other extracts. Conversely, seed oil was found to be rich in cytotoxic phytochemicals and exhibited significantly higher (p < 0.05) α-amylase inhibitory activity while remained more cytotoxic against brine shrimps than n-hexane, methanolic and aqueous extracts. Methanolic extract was found to possess significantly higher content of total phenolics and flavonoids (p < 0.05) than the seed oil and other extracts. These results suggested that J. curcas seed oil and extracts can be further investigated for antimicrobial potential and as competent bio-pesticides.

在这项研究中，确定了麻疯树籽油和脱油籽饼提取物的抗真菌、抗氧化、酶抑制（α-淀粉酶）、植物化学和细胞毒性特征。研究了针对不同植物病原真菌的抗真菌活性，包括炭疽病菌、终极腐霉、辣椒疫霉、立枯丝核菌、米双极和藤黑镰刀菌。甲醇提取物被发现是高度杀真菌相比，水提取物，Ñ -己烷提取物和种子油，抗辣椒疫霉和F.苗病菌。还发现甲醇提取物具有显着更高的抗氧化潜力（p < 0.05) 比其他提取物。相反，种子油被认为是丰富的细胞毒性的植物化学物质和表现出较高的显著（p  <0.05）α淀粉酶的抑制活性，同时保持抵抗盐水虾超过细胞毒性Ñ己烷，甲醇和水提取物。发现甲醇提取物 比种子油和其他提取物具有显着更高的总酚类和类黄酮含量 ( p < 0.05)。这些结果表明可以进一步研究麻疯树种子油和提取物的抗菌潜力和作为有效的生物农药。
