Abstract:

The chemical constituents of Swertia punicea Hemsl. were isolated by various column chromatographic methods. Fifteen compounds were obtained and identified as oleanolic acid (1), swerchirin (2), sweriaperenine (3), bellidifolin(4), gentiacaulein (5), isobellidifolin (6), 8-[(β-D-glucopyranosyl)oxy]-1,5-dihydroxy-3-methoxyxanthone (7), 5-[(β-D-glucopyranosyl)oxy]-1,8-dihydroxy-3-methoxyxanthone (8), 7-[(β-D-xylopyranosyl)oxy]-1,8-dihydroxy-3-methoxyxanthone (9), 8-[(β-D-glucopyranosyl)oxy]-1,3,5- trimethoxyxanthone (10), swertiamarin (11), tetrahydrosertianolin (12), 8-hydroxy-10-hydrosweroside (13), campestroside (14), and uridine (15). Compounds 14 and 15 were isolated from this genus and 9101213 were obtained from this plant for the first time.

Key words: Swertia punicea Hemsl., petroleum ether fraction, n-butanol fraction, xanthonoids, iridoid glycosides
