| Authors: | Kurt Hostettmann Iwao Miura |
| Abstract: | A new xanthone diglucoside (1) has been isolated from the aerial parts of Swertia perennis L. (Gentianaceae) by means of column chromatography on polyamide, followed by preparative TLC. on silica gel. From UV. and NMR. data, its structure has been established as 1,3-di-β-D -glucopyranosyl-7,8-dihydroxyxanthone or norswertianine-1,3-diglucoside. |
