It is also one of the main active ingredients in the Astragalus that is a commonly used traditional herb. CG has obvious effects of anti-oxidation, anti-virus, inhibition of melanin formation, and immunosuppression. With the advancement of modern technology, it has become a pivotal subject that the adjuvant therapy or even substitute for the synthetic drug of monomer of Chinese herb in medical field. In recent years, with the deepening of research on the mechanism of action of CG, which has been found that its pharmacological effects are very extensive, such as the anti-tumor effect and the effect on cerebrovascular diseases of CG. This review summarizes the pharmacological effects and the latest research progress of CG.展开更多
Two new flavonol glycosides (1 and 2) together with two known flavonoides (3 and 4), were isolated from the whole plant of Knoxia corymbosa willd.
