The first cyclic phenolic acid glycoside dimer and new alpha-tetralone and triterpenoid glucosides from Gentiana loureirii

Chem Pharm Bull (Tokyo). 2010 Apr;58(4):565-7. doi: 10.1248/cpb.58.565.

Abstract

Further chemical investigation of the whole plants of Gentiana loureirii led to the isolation and characterization of three new compounds, cyclic 4-O-beta-D-glucopyranosylcaffeic acid dimer (1), a new alpha-tetralone, 4-hydroxy-6-methyl-alpha-tetralone 4-O-beta-D-glucopyranoside (2), and 3beta,30-dihydroxy-12-ursen-28-oic acid 28-O-beta-D-glucopyranosyl ester (3), along with five known compounds. To the best of our knowledge, compound 1 is the first cyclic phenolic acid glycoside dimer.
