长裙竹荪子实体乙醚和乙酸乙酯提取物的化学组成分析及抑菌活性研究

Chemical composition and antimicrobial activity of the extracts with ethylether and ethyl acetate from Dictyophora indusiata

摘要: 依次用乙醚和乙酸乙酯为溶剂,对正己烷提取后的长竹荪子实体粉末进行索氏提取。乙醚和乙酸乙酯的提取率分别为1.57%和1.85%,然后采用GC-MS对乙醚和乙酸乙酯提取物的化学成分进行分析,图谱解析结果显示乙醚提取物中含有43种成分,占总含量的99.98%;乙酸乙酯提取物中含有73种成分,占总含量的99.56%。两种提取物对金黄色葡萄球菌、变形杆菌、枯草芽孢杆菌、伤寒杆菌等均有明显的抑制作用,而乙酸乙酯提取物的抑菌效果优于乙醚。

Abstract: The dry fruiting body power of Dictyophora indusiata was extracted by ethylether and ethyl acetate after n-hexane extraction. The ethylether and ethyl acetate extraction rate was 1.57% and 1.85%, respectively.The chemical composition of the extracts had been identified by GC-MS. The analysis results showed that forty-three components had been identified from ethylether extracts and their content was of 99.98%. Seventythree components had been identified from ethyl acetate extracts and their content was of 99.56%. Two kinds of extraction showed a significant antimicrobial activity to Staphylococcus aureus, Bacterium vulgare, Bacillus subtilis and Salmonella typhosa. The inhibitory effect of ethyl acetate extracts were better than that of ethylether extracts.
