摘要
目的鉴别酸藤子的生药学特征。方法对药材进行基源鉴别、性状鉴别、显微鉴别、薄层鉴别。结果酸藤子根木栓层内壁增厚,似石细胞样,内皮层细胞较小,内含棕色物,射线中可见类圆形的油细胞;茎、叶横切面均有离生式分泌腔;叶表面可见腺鳞。粉末中可见棕色块、油细胞、晶鞘纤维、草酸钙方晶、腺鳞等。黄酮类化合物的理化鉴别为阳性反应,薄层可检出芦丁斑点。结论所用方法可为酸藤子药材的鉴别和开发利用提供依据。
OBJECTIVE To identify the pharmacognostic character of Embelia laeta.METHODS The identification of origin,morphological identification,microscopic identification and thin layer identification were carried out.RESULTS The wall of the cork layer was thickened as celluliform.Endodermal cells were small and contained brown substances,In the ray of which round oil cells were found in the ray.Secreted cavity was found in the stems and leaves,and glandular scales were visible in the surface of leaves.Brown block,oil cell,crystal-sheath fiber,square crystals of calcium oxalate and glandular scales were observed in the powder.The determinations of flavonoid were positive and the spot of rutin was observed in TLC identification.CONCLUSION The results can be used to identify and exploit Embelia laeta.
