摘　　要：为清风藤属药用植物的鉴别提供参考,采用形态学和光学显微方法对黔产4种清风藤属(Sabia)药用植物的外观形态及显微特征进行观察。结果表明:1)外观形态观察,平伐清风藤为直立灌木,四川清风藤、尖叶清风藤和阔叶清风藤为木质藤本植物。2)根茎横切面光学显微观察,四川清风藤的根皮层内有石细胞环带,茎髓部无晶体;平伐清风藤的根韧皮部无石细胞环带,茎髓部有晶体;尖叶清风藤的根韧皮部石细胞连续成环,茎表皮有非腺毛;阔叶清风藤的根韧皮部石细胞断续成环,茎表皮无非腺毛。3)根茎叶粉末光学显微观察,平伐清风藤植物的根、茎、叶中均有棕色块状物质,尖叶清风藤植物的茎中有非腺毛,阔叶清风藤植物的叶中有淀粉,四川清风藤植物的叶中无淀粉。根据清风藤属药用植物的外观形态结合其显微特征可准确鉴定和区分平伐清风藤、四川清风藤、尖叶清风藤和阔叶清风藤4种药材。To provide a reference for the identification of medicinal plants of Sabia,the appearance and microscopic characteristics of four kinds of medicinal plants of the genus in Guizhou were observed by morphological and optical microscopy methods.The result showed that：1）Sabiadielsii is upright shrub, and Sabia schumanniana,Sabia swinhoei,and Sabia yunnanensis are woody vine in appearance.2 ）In microscopic characteristics of root and stem,stone cell band were found in the cortex of root and no crystal in the medulla of stem in S.schumanniana,and crystal was observed in the medulla of stem and no stone cell band in the phloem of root in S.dielsii;The authors also found stone cells band continuously in the phloem of root and non-glandular hair in epidermis of stem in S.swinhoei,and observed stone cells band intermittently in the phloem of root and no non-glandular hair in epidermis of stem in S.yunnanensis.3） There were brown lump material in the root,stem and leaf of S.dielsii,and non-glandular hairs in the stem of S.swinhoei. In the leaf of S. yunnanensis have starch but Sabia schumanniana have not. According to appearance combined with microscopic characteristics, four kinds of herbs including S.dielsii,S.schumanniana,S.swinhoei and S.yunnanensis can be identified accurately.
