Abstract:
Guangdougen is generally known as Shandougen. It is a traditional
Chinese drug. It can be used as antipyretic, antidote, anodyne or antiinflammation ag-
ent. In recent years, some compounds (alkaloids, flavones and a new glycoside) such
as cytisine, matrine, oxymatrine, pterocarpin and isoprenyl chalcone, have been isola-
ted from roots of Guangdougen for medicinal purposes. They give effects of antiarrhy-
thmia, anticancer or antiulcer.
A recent investigation reveals that the Guangdougen comes from Sophora tonki-
nensis Gagnep. (syn. Sophora subprostrata Chun et T. Chen) and Sophora tonkinensis
Gagnep. var. polyphylla S. Z. Huang et Z. C. Zhou, var. nov.
Gnangdougen is geographically restricted to SE. and NW. Guangxi and SE. Gui-
zhou and Yunnan (103-109°E, 22-26°N). They have an ecological preference for li-
mestone regions, very commonly growing in mountains of 500-800 m alt.
