Tetrasaccharide multi-esters and xanthone glycosides from the roots of Polygala wattersii
Ten new tetrasaccharide multi-esters, watteroses A-J (1-10), and two new xanthone glycosides, wattersiixanthones A (11) and B (12), were isolated from the roots of Polygala wattersii, together with 11 known compounds (10 oligosaccharide multi-esters and ...

Xanthone glycosides from Swertia franchetiana
A new xanthone glycoside ( 1) has been isolated from Swertia franchetiana together with five known xanthone glycosides. Their structures were elucidated as 7-O-[beta-D-xylopyranosyl-(1 --> 2)-beta-D-xylopyranosyl]-1,7,8-trihydroxy-3-methoxyxanthone (1 ...

A pair of novel cytotoxic polyprenylated xanthone epimers from gamboges
Two new polyprenylated xanthone epimers were isolated from gamboges of Garcillia hanburyi, and identified by detailed spectroscopic analysis as 30-hydroxygambogic acid (2a) and its (2S)-epimer 30-hydroxyepigambogic acid (2b).

Xanthone production in calli and suspended cells of Hypericum perforatum
7 pages, 4 figures, 1 table.Calli and suspended cells of Hypericum perforatum accumulated xanthones with the 1,3,6,7 and 1,3,5,6-oxygenation pattern. Xanthone accumulation was highly influenced by hormone supplementation.

Xanthones are a class of heterocyclic natural products that have been widely studied for their pharmacological potential. In fact, they have been serving as scaffolds for the design of derivatives focusing on drug development. One of the main study targets of xanthones is their anticancer activity. Several compounds belonging to this class have already
