Summary
Six new diterpene glycosides — doronicosides A, B, C, D, E, and F — have been detected in the roots ofDoronicum macrophyllum Fisch. The qualitative and quantitative composition of the sugar chain of doronicoside D has been established. It has been shown that the negative aglycone of all the doronicosides is 15β-hydroxy-(−)-kaur-16-en-19-oic acid, which, in the process of hydrolysis, is converted into 15-oxo-(−)-kauran-19-oic acid.
