Plants in genus Kadsura,belong to the Schisandraceae family including genus Schisandra and genus Kadsura,revealed folk efficacy and medicinal application in the treatment of rheumatoid arthritis and gastroenteric disorders for a long history.Previous study indicated that plants from genus Kadsura mainly contain lignans,triterpenoids and essential oils,and showed the active compounds were lignans and triterpenoids.Among all compounds from Schisandraceae family,the triterpenoids between the genus Schisandra and genus Kadsura had obvious differences.In this paper,we reviewed214triterpenoids and their pharmacological activities reported from genus Kadsura in the past30years(from1987to2017),aiming to provide reference for further study. 展开更多
