山指甲与扭肚藤的比较鉴别研究

【目的】从植物的外观性状和显微特征等方面鉴别山指甲(Ligustrum sinense Lour.)和扭肚藤(Jasminum elongatum(Bergium)Wild.)的生药学异同点。【方法】采集2种植物新鲜的茎、叶、花、果为样品,采用体视镜进行外观形态鉴别;采用显微镜对2种植物的茎横切面、叶横切面、叶上下表皮撕片以及粉末进行显微鉴别。【结果】原植物形态鉴别:山指甲圆锥花序,花冠漏斗形;扭肚藤聚伞花序,花冠高脚碟状。显微特征鉴别:山指甲茎髓部较小,而扭肚藤茎髓部较大;山指甲茎粉末中石细胞孔沟或层纹多不明显,导管多为网纹导管,而扭肚藤茎粉末中石细胞孔沟或层纹明显,导管多为螺纹导管。【结论】研究结果可为山指甲和扭肚藤的药材鉴定及其开发利用提供依据。

Identification of Ligustrum sinense Lour. And Jasminum elongatum (Bergium) Wild.

Objective To identify the Ligustrum sinense Lour.and Jasminum elongatum(Bergium) Wild.from the macroscopic appearance and microscopic features.Methods Fresh samples of stems,leaves,flowers and fruits of the two kinds of medicinal plants were harvested.Stereoscopy was used for the observation of macroscopic appearance of Ligustrum sinense Lour.and Jasminum elongatum (Bergium) Wild.,and the microscopy was used for the examination of their microscopic features of stem and leaf cross section,tear film and the powder of leaf upper and lower epidermis.Results Original plant characteristics of the two kinds of species were as follows:Ligustrum sinense Lour.had a racemes and funnel-shaped corolla,while Jasminum elongatum (Bergium)Wild.had a cymes and salverform corolla.Microscopic identification results were as follows:the stem pith of Ligustrum sinense Lour.was smaller,and the stem pith ofJasminum elongatum(Bergium) Wild.was bigger;Ligustrum sinense Lour.stem powder had less pit or texture in the sclereids,and had reticulate vessels,and Jasminum elongatum(Bergium) Wild.stem powder had apparent pit or texture in the sclereids,and had spiral vessels.Conclusion The results will provide a basis for the identification,exploitation and utilization of Ligustrum sinense Lour.and Jasminum elongatum(Bergium) Wild.
