Triterpene glycosides of Gypsophila trichotoma III. Structure of trichoside B

Summary The structure of trichoside B — a gypsogenin tetraoside fromGypsophila trichotoma Wend. — has been established. The glycosidic carbohydrate chain is O--D-glucopyranosyl-(1 3)-O--D-glucuronopyranosyl and the acyloside chain is O--D-glucopyranosyl-(1 4)-O--D-galactopyranosyl.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR.

Triterpene glycosides of Gypsophylla trichotoma II. The structure of trichoside A

Summary The structure of trichoside A — a gypsogenin trioside fromGypsophylla trichotoma Wend. — has been established. The O-glycosidic moiety is the O--D-glucopyranosyl-(1 3)-O--D-glucopyranoside grouping and the O-acyl moiety is D-galactose.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR.

Triterpene glycosides ofSapindus mukorossi

Conclusions The structure of two triterpone glycosides fromSapindus mukorossi Gaertn. has been established. It has been shown that sapindoside A is hederagenin 3-O--L-arabinosyl-(2 1)--L-rhamnopyranoside and sapindoside B is the 3-O--L-arabopyranosyl-(2 1)-O--L-rhamnopyranosyl-(3 1)--D-xylopyranoside.
