中文摘要：

目的：比较鄂西地区竹节参野生与栽培品种药材性状、显微特征及总皂苷含量差异。方法：用显微鉴别方法对竹节参野生与栽培品种药材性状、横切面及粉末显微特征进行对比,明确生药学差异;用香草醛-高氯酸法测定总皂苷含量。结果：药材性状方面,野生品较栽培品颜色深,直径小,表面粗糙;显微组织方面,野生品存在色素块,栽培品中未发现,且野生品中单位面积草酸钙簇晶较多,木质部导管直径较大;总皂苷含量方面,栽培品总皂苷含量显著高于野生品。结论：野生品与栽培品竹节参生药学特征及总皂苷含量存在一定差异。

英文摘要：

Objective： To compare the difference of macroscopic and microscopic characteristics and total saponin content between wild and cultivated product of Panax japonicus from the west of Hubei province.Methods： Cleared the difference of wild and cultivated product of Panax japonicus by macroscopic and microscopic characteristics of powder and transversection and determined the content of total sponin by the vanillin-perchloric acid.Results： Compared with cultivated product,in medicinal properties,the wild one was darker,with shorter diameter and rougher surface.In microscopic features,wild product had pigment,while the cultivated one had none;Moreover,the calcium oxalate crystal were more and the xylem bigger in wild product.As for total saponins,cultivated product had more total ginsenosides than the wild one.Conclusion： There are certain differences in macroscopic and microscopic characteristics and total ginsenosides between wild and cultivated product of Panax japonicus.
