中药葛根及其同属植物的资源利用和评价

THE SOURCE UTILIZATION AND EVALUATION OF MEDICAL KUDZU AND KOOTS FROM THE GENUS PLANTS PUERARJA DC,IN CHINA

对我国葛属（ＰｕｅｒａｒｉａＤＣ，）９种和１变种植物进行了调查研究，认为目前国内市售中药葛根的主流品种为野葛Ｐ，ｌｏｂａｔａ（Ｗｉｌｌｄ．）Ｏｈｗｉ和粉葛Ｐ．ｔｈｏｍｓｏｎｉｉ）Ｂｅｎｔｈ．。野葛在我国大部份省区都有分布，资源最为丰富；粉葛在广西载培历史悠久；其他种主要分布在西南地区，并有少数种在当地作中药葛根用。从成分分析结果看，野葛的葛根素（ｐｕｅｒａｒｉｎ）及总黄酮含量显著高于本属其它植物，粉葛次之。除野葛和粉葛外其他种均不宜作葛根药用。峨嵋葛Ｐ．ｏｍｅｉｅｎｓｉｓＷａｎｇｅｔＴａｎｇ是个有争议的种，我们比较了化学成分的含量，其结果与粉葛相近，而与山葛藤有所区别，有待进一步研究。

Accordjng to the investigtion of 9 species and l varity of Pueraria DC,P.lobataand P,thomsonii are regarded as the main commedity in traditional Chinese drug“Kudzu”.P. lobata,which distributed in most provinces in China, has aboundant resources.P. thomsonii has been cultivatedin Guangxi for a long time,other species are mainly distributed in southwestern China and a few ofthem are used as Kudzu in some areas. Based on the resuIt of quantitative determination of effectivecompounds,other Pueraria species can not be used as Kudzu except P.thomsonii and P.thomsonii.As to thepresence of species argument of P.omeiesis,further study is necessary,because its compostionquantity is similar to that of P,thomsonii,but different from that of P,montana。
