葛藤乃豆科植物野葛(Pueraria eobata (Wilid)Ohwi)(其根系中医常用药物之一葛根)的藤茎。我们已从葛藤中提取分离,鉴定出3种异黄酮类化合物——大豆甙元(Daidzein)、大豆甙(Daidzin)和葛根素(Puerarin),而这3种成分恰恰是葛根中重要的活性物质,因此测定此3种异黄酮类化合物的含量是评价葛藤内在质量的重要指标,也是葛藤代替葛根入药的科学依据。
Getang is the cane of the leguminous plant Pueraria eobata (Wilid) Ohwi (which is one of the root medicines commonly used in traditional Chinese medicine, Pueraria lobata). We have extracted and separated from GeTengzhong and identified three isoflavone compounds, Daidzein, Daidzin, and Puerarin. These three components are just important active substances in Pueraria lobata. Therefore, the determination of the content of these three kinds of isoflavone compounds is an important indicator for evaluating the intrinsic quality of Pueraria lobata, and it is also the scientific basis for the use of Pueraria lobata instead of Pueraria.
