Ohwi or P. thomsonii Benth. It shows significant pharmacological activities in the treatment ofcardiovascular diseases, hypertension, and diabetes. This review summarizes progress in the chemistry study of Puerariaspecies, mainly covering the classes of flavonoids, puerosides, coumarins, triterpenoids, and triterpene saponins. Qualitative andquantitative chemical analyses are also covered.展开更多
