UPLC (Ultra Performance Liquid Chromatography) identification method for poria with hostwood, poria cocos and poria cocos peel medicinal materials and formula granules

The invention discloses a UPLC (Ultra Performance Liquid Chromatography) identification method for poria with hostwood, poria cocos, poria cocos peel medicinal materials and formula granules, which comprises the following steps: determining specified values of relative retention time of the poria with hostwood, poria cocos, poria cocos peel medicinal materials and formula granules through a high performance liquid chromatography; the relative retention time of the corresponding test solution is within +/-10% of the corresponding specified values of the poria with hostwood, the poria cocos, the poria cocos peel medicinal materials and the formula granules. The method can effectively identify poria with hostwood, poria cocos and poria cocos peel medicinal materials and formula granules. 本发明公开了一种茯神、茯苓、茯苓皮药材及配方颗粒UPLC鉴别方法，其通过高效液相色谱法确定茯神、茯苓、茯苓皮药材及配方颗粒的相对保留时间的规定值，相应供试品溶液的相对保留时间分别落在茯神、茯苓、茯苓皮药材及配方颗粒对应规定值的±10％范围之内。本发明能够有效的鉴别茯神、茯苓、茯苓皮药材及配方颗粒。
