近年来,我区发现个别药材经营部门及个体药贩大量收购酷似药材防己的植物根,以防己为名大量销往外省区药材经营部门。笔者因此深入产地采集其植物标本及对口药材进行鉴定,发现其来源为茶茱萸科植物小果微花藤Iodes vitiginea(Hance.)Hemsley与瘤枝微花藤I.sequinii(Hevl.)Rehder。两者在产地和我区均无药用习惯。本文对小果微花藤根和瘤枝微花藤根作了性状、显微及薄层层析鉴定,并与防己Stephania tetrandra进行比较鉴别。
In recent years, our district has discovered that a large number of individual drug dealers and individual drug dealers have acquired a large number of plant roots that resemble medicinal herbs. In order to prevent their own name from being sold to a large number of drug companies in other provinces and regions. Therefore, the authors collected the plant specimens from their production areas and identified their counterparts. They found that the source was the Iodes vitiginea (Hance.) Hemsley and the I. sequinii (Hevl.) Rehder. Both have no medicinal habits in the area of production and in our district. In this paper, the traits, microscopic and thin-layer chromatographic characterization of the roots of the micro-flowering vines and the micro-flowering vines were performed and compared with Stephania tetrandra.
