Objective: To study the chemical constituents of Gentiana striata.
Methods: The constituents were isolated from the whole herb of Gentiana striata by recrystalization, silica gel column chromatography, polyamide column chromatography and Sephadex LH-20,etc. Their structures were elucidated through MS, 1H-NMR, 13C-NMR.
Results: -8 compounds were isolated and identified as: Desoxyloganin (1), Gmephiloside (2), 5,7,4'-trihydroxy-3'-methoxyflavone (3), (+)-8-hydroxypinoresinol (4) 3S,5R, 6R, 9S-tetra-hydroxymegastigmane (5), Quercetin-3-O-beta-D-glucoside (6), Ferulic acid (7) and Ursolic acid (8).
Conclusion: All the compounds are isolated for the first time from Gentiana striata.
