刺芹总黄酮的微波辅助提取及抑菌性研究
Study on Microwave -assist Extraction and Anti -microbial Activities of Total Flavones from the Eryngium foetidum
摘要
Abstract
Microwave -assist technology was used to extract total flavonoids from Eryngium foeti-dum.The influence on this assay strategy was carefully optimized by single factor test and orthogonal design test of L9 (34 ).Meanwhile,the bacteriostatic test of resulting extract was further emulated to escherichia co-li,bacillus and saphyloccocus aureus.The results indicated that when solid -1iquid ratio was 1:25g/mL, the ethanol was 70% (wt %),microwave power was 350W,and extracting time was 60s,the optimal a-mount of total flavonoids was 5.07%.In addition,the extract has obvious antibacterial effect on saphylocco-cus aureus and bacillus ,but has no obvious effect on .escherichia coli.关键词
