Triterpenoids from Rubi Fructus (Bogbumja)

Abstract

The dried unnipe fruits of Rubus sp. (Rubi Fructus, Bogabunja) have yielded $\beta$-sitosterol glucoside and four urs 12 en-28-oic acid derivatives, three of which were as their glucosiders. They were identified as 23-hydroxytomentic acid, rosamultin, niga-ichigosides $F_1\;and\;F_2$ on the basis of spectral data.
