远志与卵叶远志的鉴别研究

目的：对不同时期采集的远志与卵叶远志及远志炮制品、伪品进行对比鉴别研究,为临床合理用药提供依据。方法：应用性状鉴别、薄层色谱法和紫外光谱法进行鉴别实验。结果：远志与卵叶远志基源、性状相同与远志炮制品薄层色谱主斑点一致,紫外光谱吸收图谱一致,远志及卵叶远志地上部分与地下部分,薄层色谱主斑点一致,其他斑点差异较大,紫外图谱也有明显差别;伪品远志薄层色谱图及紫外光图谱与正品明显不一致。结论：该方法可用于远志不同品种、不同采集期、不同制品及其伪品的定性鉴别,可将卵叶远志作为远志的开发品种之一。

Study on the Identification of Polygala Tenuifolia Willd and Polyagla Sibirica L

Objective： To study on the identification of polygala tenuifolia willd,polyagla sibirica L,processed products and fake products collected in different periods and to provide the basis for clinical rational drug use. Methods： The experiment was carried out using the differential character identification,TLC and UV spectroscopy. Results： The same source and characters of polygala tenuifolia willd and polyagla sibirica L,polygala raw and processed products have the same thin layer chromatography main spots and ultraviolet spectral absorption spectrum. TLC spots of underground part and upper part of polygala tenuifolia willd. and polyagla sibirica L are consistent,other spots differences. UV spectrum also has the obvious difference; Thin layer chromatography and ultraviolet spectrum of fake products and genuine polygala are obviously inconsistent. Conclusion： The method can be used for the qualitative identification for polygala tenuifolia willd in different period,different varieties,different products and its adulterants,so polyagla sibirica L. can be used for one of the development species of polygala tenuifolia willd.
