柿蒂及其未成熟品的鉴别研究

目的 对柿蒂及其未成熟品进行鉴别研究，为柿蒂的鉴别提供实验依据。方法 采用性状、显微鉴别，薄层鉴别及液相色谱法进行含量测定，对二者进行鉴别研究。结果 两者性状区别明显；显微鉴别石细胞存在明显差异；薄层鉴别中以没食子酸为对照品，未成熟柿蒂中没食子酸丰度明显高于柿蒂；未成熟柿蒂中所含没食子酸含量高于柿蒂。结论 性状鉴别、石细胞显微特征以及没食子酸含量可以为两者的鉴别提供参考依据。

Comparative Study on the Calyx Kaki and Its Immature Products

OBJECTIVE To provide experimental basis for the comparative study of Calyx Kaki and its immature products. METHODS The morphological identification, microscopic identification, TLC and HPLC identification were adopted to distinguish these two materials. RESULTS There were obvious differences in morphological identification and microscopic identification of stone cells between the two, TLC identification revealed that the content of Gallic Acid in immature products was higher than that in Calyx Kaki by using Gallic acid as reference. HPLC identification also indicated the same result. CONCLUSION The morphological identification, microscopic characteristics of stone cells, combing with the determination of Gallic Acid can be the feasible methods that used to distinguish two materials.
