從絞股藍(lán)中聯(lián)合提取皂苷、黃酮和多糖工藝研究

內(nèi)容摘要：研究了從絞股藍(lán)中按皂苷、黃酮、多糖先后次序聯(lián)合提取皂苷、黃酮和多糖工藝，與單獨(dú)提取工藝進(jìn)行對(duì)比。結(jié)果表明聯(lián)合提取工藝中提取率：皂苷3.98%、黃酮1.36%、多糖1.40%。單獨(dú)提取工藝中提取率：黃酮1.75%、多糖1.96%。5g原料的聯(lián)合提取工藝與15g原料的單獨(dú)提取工藝相比，原料的利用率得到較大的提高。

Technology research of  saponins, flavonoids and polysaccharides joint extraction from gynostemma pentaphyllum
Abstract: According to the order of saponins, flavones, polysaccharides, A joint extraction of saponins,flavones, polysaccharides from gynostemma pentaphyllum had been proceeded, which was compared with single extraction. The results of the study showed that comprehensive extraction yield was saponins 3.98%, flavones 1.36%, polysaccharides 1.40%.Single extraction yield was flavones 1.75% ,polysaccharides 1.96%. Compared joint extraction of 5g raw material with Single extraction of 15g raw materials, the utilization rate of raw materials had been increased.
Key words：Gynostemma pentaphyllum; saponins; flavones; polysaccharides
