Extraction and Antibacterial Effect of Flavonoids from Water Chestnut Peel
摘要
Abstract
The effect of extraction solvent,acetic acid concentration,extraction temperature, time and solid-liquid ratio(g/mL)on the extraction rate of flavonoids from the water chestnut peel was studied. The optimized parameters was obstained with the single factor and orthogonal design. The results showed that 75% acetic acid concentration,70℃,solid-liquid ratio 1∶14 and 6 h,the extraction rate of flavonoids reached 1. 56%. The antibacterial effect of flavonoids in the water chest-nut peel to Escherichia coli,Bacillus subtilis,Staphyloccocus aureus and Pseudomonas aeruginosa were measured. The results showed that extracts of the water chestnut peel had the antibacterial ef-fect to the 4 species germs,but the amount of flavonoids content has no obvious correlation with the antibacterial effect,It can be inferred that the antibacterial substance in extractive is not only flavo-noids. The extracting flavonoids and antibacterial effect to 4 species germs had no linear relationship when the flavonoids extracted on different temperature ranged from 50℃to 80℃.关键词
