摘要: 为探究湖北贝母(Fritillaria hupehensis Hsiao et k.c.Hsia)石油醚段的抗菌活性和化学成分,将湖北贝母经60%乙醇溶液超声提取获得总浸膏,再采用石油醚萃取获得石油醚段浸膏,利用滤纸片法、稀释倒平板法、超微量紫外分光光度计以及电导仪对湖北贝母石油醚段的抗菌活性和机制进行了探索;同时,利用GC-MS、1D和2D NMR等对湖北贝母石油醚段的成分进行了探索。结果表明,湖北贝母石油醚段溶液对于苏云金芽孢杆菌、绿脓杆菌有中度敏感抑制活性,对肺炎克雷伯杆菌ATCC13883、金黄色葡萄球菌ATCC29213、枯草芽孢杆菌有轻度敏感抑制活性。其中,只有苏云金芽孢杆菌、枯草芽孢杆菌、绿脓杆菌的MIC/MBC小于4.0 mg/mL。湖北贝母石油醚段很可能通过破坏细胞膜从而减缓了苏云金芽孢杆菌、枯草芽孢杆菌、绿脓杆菌生长,从而达到抗菌的效果,并获得了对应总离子流中的27种化合物。

Abstract: Study on compositions and antibacterial activities of petroleum ether extracts from Fritillaria hupehensis Hsiao et k.c.Hsia,Fritillaria hupehensis Hsiao et k.c.Hsia were collected from Enshi area,Hubei province,China,whoes total extract was obtained by ultrasonic extraction with ethanol solution (60%).And the total extract to obtain petroleum ether segment were extracted.The antibacterial activity and mechanism of petroleum ether segment of Fritillaria hupehensis were studied by means of filter paper method,dilution pour plate method,ultra micro ultraviolet spectrophotometer and conductivity meter.The composition of petroleum ether segment from Fritillaria hupehensis was studied by means of GC-MS,1D and2D NMR.Results showed that Hubei Fritillaria petroleum ether solution was moderately inhibitory sensitive on Bacillus thuringiensis and Pseudomonas aeruginosa,and mildly inhibitory sensitive on Klebsiella pneumonia ATCC13883,Staphylococcus aureus ATCC29213,and Bacillus subtilis.Among them,the MIC/MBC of Bacillus thuringiensis,Bacillus subtilis,and Pseudomonas aeruginosa were less than4.0 mg/mL.Through the exploration of antibacterial mechanism,the petroleum ether section of Fritillaria fragrans Hubei probably slowed the growth of Bacillus thuringiensis,Bacillus subtilis,Pseudomonas aeruginosa by destroying the cell membrane,and finally achieved antibacterial effect.This study also explored the composition of the petroleum ether Extracts from Fritillaria hupehensis Hsiao et k.c.Hsia.Total ion chromatograms of the petroleum ether Extracts from Fritillaria hupehensis Hsiao et k.c.Hsia were obtained and compared with the NIST08.LIB standard library based on retention time and mass spectrometry data.Finally27 compounds of the total ion chromatogram were obtained.

Key words: Fritillaria hupehensis Hsiao et k.c.Hsia, antimicrobial activity, petroleum ether extract, compound
