Triterpenoid glycosides from the fruits of Kochia scoparia

From the fruits of Kochia scoparia (L.) Schrad, five triterpenoid glycosides were isolated for the first time from this plant. They were elucidated as momordin Ic, the 6'-methyl ester of momordin Ic, momordin IIc, 2'-O-beta-D-glucopyranosylmomordin Ic, and 2'-O-beta-D-glucopyranosylmomordin IIc on the basis of spectral and chemical methods. The last two saponins are new natural products.
