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.
