比较小半夏加茯苓汤单煎与合煎之间的差异。采用水提醇沉法提取多糖,以葡萄糖标准品进行对照测定多糖含量,紫外检测波长为198nm。通过峰位和吸光度值比较单煎液与合煎液的紫外扫描差异。小半夏加茯苓汤合煎液提取的多糖量较单煎液多,单煎液与合煎液紫外扫描基本一致,合煎液吸光度值较高。小半夏加茯苓汤合煎较单煎为优,尚不能完全说明是否能用免煎颗粒调冲的小半夏加茯苓来替代传统汤剂。
Smaller Xia Xiajia Fuling soup single fried and co-fried the difference between. Polysaccharides were extracted by water extraction and alcohol precipitation method, and the content of polysaccharides was determined by glucose standard. The UV detection wavelength was 198nm. The differences of UV scanning between single decoction and co-decoction were compared by peak position and absorbance. Small Pinellia plus Poria Decoction decoction extraction of polysaccharides more than a single decoction, single Decoction and decoction UV scanning is basically the same, the decoction of the higher absorbance value. Small Pinellia plus Poria Decoction combined decoction than single decoction is excellent, still can not fully explain whether the use of decocted particles to tune the small Pinellia Poria to replace the traditional decoction.
