- Phytochemical investigation of the roots of Leea thorelii led to the isolation of nine compounds. Their structures were determined from spectroscopic data as bergenin (1), 11- O -acetyl bergenin (2), 11- O -(4′- O -methylgalloyl) bergenin (3), 3,5-dihydroxy-4-methoxybenzoic acid (4), (−)-epicatechin (5), 4″- O -methyl-(−)-epicatechin gallate (6), (−)-epicatechin gallate (7), microminutinin (8) and stigmasterol. Compounds 1 – 8 are reported for the first time from this plant, and this is also the first report of the presence of 1 , 3 , 4 , 6 and 8 in the Vitaceae family.
