General Description

8-hydroxy-1,3,5-trimethoxy-9H-xanthen-9-one is a chemical compound with a xanthene structure. It is a derivative of xanthene, which is a fluorescent dye often used in biological and chemical research. This particular compound contains three methoxy (CH3O) groups and a hydroxyl (OH) group, as well as a xanthene core. It has potential applications in the development of fluorescent dyes and organic light-emitting diodes (OLEDs). The compound's unique structure may also make it useful in the study of chemical reactions and the development of new organic compounds.

A XANTHONE GLYCOSIDE FROM SWERTIA SPECIOSA

A new xanthone glycoside, 1-hydroxy-8-glucosyloxy-3,5-dimethoxyxanthone, alongwith 1,8-dihydroxy-3,7-dimethoxyxanthone, 3-methoxy-1,5,8-trihydroxyxanthone and ursolic acid have been isolated and identified from the aerial parts of Swertia speciosa.Key Word Index-Swertia speciosa; Gentianaceae; high altitude plants; 1-hydroxy-8-glucosyloxy-3,5-dimethoxyxanthone; 1,8-dihydroxy-3,7-dimethoxyxanthone; 3-methoxy-1,5,8-trihydroxyxanthone; ursolic acid.

XANTHONE AND FLAVONOL CONSTITUENTS OF SWERTIA HOOKERI

The whole plant of Swertia hookeri, collected at flowering has been shown to contain two tri- and nine tetraoxygenated free, glucosyloxy, and stearyl ester xanthones and one flavonol stearyl ester.Among these, three are previously unreported in nature and one was known previously only as a synthetic compound.The xanthones are based on 1,3,5-, 1,3,5,8- and 1,3,7,8-oxygenated systems with the middle oxygenation pattern predominating.The two ester compounds appeared only at the flowering stage.Plants collected at the pre-flowering stage gave the corresponding free compounds.The biochemical and biological significance of these findings are appraised.Key Word Index - Swertia hookeri; Gentianaceae; 1-O-stearyl-3,5-dimethoxyxanthone; 3-O-stearyl-3',4',5,7-tetra-O-methylquercetin; 1-hydroxy-3,5-dimethoxyxanthone; tetraoxygenated xanthones; 8-O-β-D-glucosyl-1,3-dihydroxy-5-methoxyxanthones; 8-O-β-D-glucosyl-1,5-dihydroxy-3-methoxyxanthone.

A New Xanthone Glycoside from Swertia angustifolia Buch-Ham ex. D. Don

The structure of a new xanthone glycoside isolated from the whole plant of Swertia angustifolia Buch-Ham ex.D.Don has been established as 1,5-dihydroxy-3-methoxyxanthone-8-O-β-D-glucoside (I) on the basis of spectral data (IR, UV, PMR) and chemical studies.
