窑归多糖(Angelica sinensis polysaccharide,简称ASP)是窑归的有效成分之一,具有增强免疫力,抑制肿瘤等药理作用。采用热水浸提法和微波辅助法提取窑归多糖,结果表明:热水浸提法提取效率高于微波提法。提取窑归根多糖的最佳工艺条件为:温度100℃,pH7.0,料液比1∶40,时间为2.5 h。通过比较窑归根和茎中多糖的含量,得知窑归多糖的主要分布在其根中。

Angelica sinensis polysaccharide (referred to as ASP) is one of the active ingredients of kiln return, with enhanced immunity, inhibition of tumor and other pharmacological effects. The hot water extraction method and microwave-assisted extraction of kiln polysaccharide, the results show that: extraction efficiency of hot water extraction method is higher than microwave extraction. The optimum conditions of extraction of polysaccharides from kiln were as follows: temperature 100 ℃, pH7.0, solid-liquid ratio 1:40 and time 2.5 h. By comparing the contents of polysaccharides in the roots and stems of Kiln, the main distribution of polysaccharides in Kiln was found in the roots.
