摘　　要：目的鉴定目前临床上使用的商品贯众的植物来源。方法收集全国各省市的商品贯众,分别对其进行性状鉴定、显微鉴定,根据叶柄基部性状特征以及横切片的维管束形状、数目、排列特征、分泌物的有无等显微特征确定其原植物来源。结果经过对来自18个省市的23份商品贯众样品的性状和显微鉴定,其原植物来源有5种,分别为鳞毛蕨科鳞毛蕨属植物粗茎鳞毛蕨(Dryopteris crassirhizoma)、辽东鳞毛蕨(Dryopteris peninsulae);乌毛蕨科狗脊蕨属植物狗脊蕨(Woodwardia japonica)、单芽狗脊蕨(Woodwardia unigemmata);乌毛蕨科乌毛蕨属植物乌毛蕨(Blechnum orientale)。结论目前我国大部分地区临床使用的贯众并非我国药典所收载的绵马贯众的原植物粗茎鳞毛蕨,而是来自形态类似的不同科属的蕨类植物,急需对各商品贯众进行化学成分、药理活性等方面的深入研究。Objective To identify the plant origin of commercial Rhizonut Dryopteris Crassirhizoma applied in clinic at present. Method The samples of commercial Rhizoma Dryopteris Crassirhizoma were collected nationwide and then the trait identification and microscopic identification were conducted. The plant origin of commercial Rhizoma Dryopteris Crassirhizoma was determined according to the characters of basal potion of the leaf and stalk, as well as the microscopic features of sample transverse section, including the shape, number, distributive feature and secretion of vascular bundle. Result After the trait identification and microscopic identification on 23 samples collected from 18 provinces, cities and autonomous regions of China, there were 5 plant origins of commercial Rhizoma Dryopteris Crassirhizoma determined, i. e. Dryopteris crassirhizoma , D. peninsulae , Woodwardia japonica, W. unigemmata , Blechnum orientale, and all of them were of the Dryopteridaceae family and Dryopteris genera. Conclusion The commercial Rhizoma Dryopteris Crassirhizoma used in clinic at present is not the original plant--Dryopteris crassirhizoma, which was recorded in the National Pharmacopeia of People＇s Republic of China, but pteridophyte from different families and generas being similar to Dryopteris crassirhizoma in morphological characters. The chemical principles and pharmacological activities of these different kinds of commercial Rhizoma Dryopteris Crassirhizoma should be studied further.
