The pericarps ofGleditschia triacanthos L. have yielded a new triterpene glycoside — triacanthoside A1 — and it has been shown that it has the structure of echynocystic acid 3-O-[β-D-xylopyranosyl-(1→4)-α-L-arabopyranosyl-(1→3)-β-D-glucopyranoside].
It has been shown that the O-glycosidic moiety of triacanthoside G coincides in structure with triacanthoside A1. The O-acyloside moiety of triacanthoside G contains the trisaccharide D-glucopyranosyl-(1→3)-O-L-arabopyranosyl-(1→4)-O-L-rhamnopyranose.
