| Abstract: | Ampelopsis powder was extracted from ampelopsis by hot-water extraction method.Flavonoids and polyphenol were also determined.Four primary factors were studied in the experiment.The most suitable conditions for the extractions were as follows: the solid-liquid ratio was 1∶30,extracting temperature was 90 ℃,extracting time was one hour,double extraction.Under such condition,the extraction yield of ampelopsis powder was 40.8%.The concentration of flavonoids and polyphenol in the extract is 13.64% and 9.80%. |
