| Abstract: | The comprehensive extraction technology of flavonoids and polysaccharide from Stigma maydis is introduced,and its extraction rate was regarded as the assessment index.The reflux and ultrasonic method was used to extract more polysaccharide and flavones for three times.Extraction time is 1h、1h、0.5h respectively.The results indicate that the extraction rate of polysaccharide from 100g stigma maydis was 4.44% by the reflux method and 4.47% by ultrasonic method;the extraction rate of flavones was 0.93% by reflux method and 0.84% by the ultrasonic method. |
