Schinortriterpenoids from Tujia ethnomedicine Xuetong—The stems of Kadsura heteroclita

In the present work, we take advantage of the characteristic NMR signal (δC-10 = 96.0–99.9) for guiding the isolation of schinortriterpenoids (SNTs) from n-butanol fraction of stems of Kadsura heteroclita which is a Tujia ethnomedicine with trivial name “Xuetong”. This effort resulted in the identification of three unreported 3,4:9,10-disecocycloartane triterpenoids xuetongdilactones A-C and three undescribed SNTs xuetongdilactones D-F, along...
