摘　　要：为有效利用和深度开发猪苓,从不同方面比较论证微粉提取优势,采用微粉碎技术对猪苓药材进行粉碎,制备过300目筛微粉,并对微粉及普通粉(过80目筛)进行TLC、干浸膏得率及总糖含量对比。结果表明:猪苓微粉粒径均匀,菌丝团块少;通过TLC图谱可知提取物所含功能成分有所增加;猪苓微粉干浸膏得率为32.50%,为普通粉的2.32倍,为药材饮片的11.08倍;总糖得率为4.74%,为普通粉的13.37倍,为药材饮片的81.29倍。TLC,dry extract yield and total sugar content of micropowder（pass 300 mesh）of P.umbellatus smashed by the micropowder technique and common powder（pass 80mesh）of P.umbellatus smashed by the traditional technique were compared to effectively utilize and develop P.umbellatus resources and demonstrate the advantage of micropowder technique from different respects.Results：micropowder has even particle size and few hyphal coils.The functional components in micropowder are higher than common powder by TLC chromatogram.The dry extract yield of micropowder is 32.50%,2.32 times and 11.08 times as many as common powder and decoction pieces respectively.Total sugar content of micropowder is 4.74%,13.37 times and 81.29 times as many as common powder and decoction pieces separately.
