Abstract:

To study the volatile components and antibacterial activity of ethyl acetate component of F. hupehensis, the ethyl acetate component of F. hupehensis in Enshi region was selected as the research object. The filter paper method was used to test the antimicrobial activity against 11 clinically resistant bacteria. Microbroth dilution method was used to determine the MIC value of the tested bacteria. The volatile components were identified by GC-MS and the content of peiminine was determined by gas chromatography. The results showed that: the ethyl acetate had medium inhibitory activity against Bacillus thuringiensis, Vibrio alginolyticus XSBZ14, and Acinetobacter baumannii ATCC 19606, and it’s MIC values was 2.37, 5.93 and 11.86 mg·mL-1 respectively; the antibacterial activitys of ethyl acetate fraction of Hubei Fritillaria was significantly different from that of peiminine, which was proved that peiminine was not the main antibacterial agent in the ethyl acetate component of Fritillaria hupehensis. A total of 16 volatile metabolites were identified, including aliphatic hydrocarbons (4.55%), fatty acids (24.07%) and alkaloids (23.02%). The content of peiminine in the ethyl acetate fraction of F. hupehensis was (16.19±0.06) mg·g-1, and the average recovery was 96.58%, the relaitve standard deviation was 3.98%. Excellent and broad spectrum antibacterial activity of ethyl acetate component of F. hupehensis provided an important reference for the development of new natural antibiotics from plant sources.
