Abstract:
Physalis. alkekengi fruit has long been used in traditional Chinese medicine for tumor therapy. In the present study, using plasmids that encode ovalbumin (OVA) gene, we investigate the adjuvant activity of a polysaccharide fraction (PPSB) isolated from P.alkekengi fruit. Formulation by simple procedures of mixing of the OVA-encoding pCI-neo-sOVA plasmid with PPSB not only induced... More
Abstract:
Purpose:Optimize water-alcohol technology for extracting polysaccharide from blood-supplementing angelica sinensis decoction to improve the extraction rate. Method:Draw the standard curve of glucose reference substance and build the regression equation to calculate the polysaccharide content. Investigate the effect of water addition times, extraction duration, extraction times, ethanol concentration for ethanol precipitation and times of ethanol precipitation... More
