New Acyclic Triterpenoid Glycoside Constituent from the Fruits of Lycium Chinense

One new acyclic triterpenoid constituent as 14,18,22-trimethyr 3 alpha,5 alpha,17 alpha,19 alpha,22 alpha-pentahydroxytetracosan-25,26,27-trioic acid-3 alpha-O-alpha-L-glucofuranosyl-(6a -> 1'a)-O-alpha-L-glucopyranosyl-(6'a-1"a)-O-alpha-L-glucopyranosyl-5 alpha-O-alpha-L-glucofuranosyl-(6b -> 1"b)O-alpha-L-glueopyrunosyl-(6'b -> 1"b)-17 alpha-O-L-glucopyranosyl-(6d-1'c)-O-L-glucopyranosyl-(6'c -> 1"c)-glucopyranosyl-19 alpha-O-Lglycopyranosyl-(6d-1'd)-O-alpha-L-glucopyranosyl-O-alpha-L-glucopyranoside-(1) was isolated and identified froth the fruits of Lychun thinense. The chemical structure of the new compound was elucidated by 1D and 2D NMR spectroscopic techniques (COSY, PIMBC and HSOC)-aided by FAR mass and IN spectra.
