[目的 ]探讨匙羹藤茎与叶鉴别的方法。 [方法 ]采用显微横切面和紫外—可见分光光度法对匙羹藤茎与叶进行鉴别。 [结果 ]其横切面可以作为鉴别特征的较多 ;而紫外—可见光谱的鉴别特点不多、专属性不强。 [结论 ]匙羹藤茎与叶的鉴别可以用横切面显微进行鉴别。
[Objective] To explore the method of distinguishing stems and leaves from the spoon. [Methods] Microscopic cross-section and UV-visible spectrophotometry were used to identify the stems and leaves of Gymnema. [Results] The cross-section can be used as a discriminating feature; UV-visible spectroscopy has few identification features and is not very specific. [Conclusion] The identification of the stem and leaf of Gymnema can be identified by cross-section microscopy.
