| Abstract: | Nine known xanthones were isolated from the ethyl acetate part of 95% ethanol extracted from the whole herb of Swertia cincta. Their structures were established on the basis of spectroscopic analysis and compared with the data reported in the relevant literature,and characterized to be( 1) 2,8-dihydroxy-1,6-dimethoxy-xanthen-9-one,( 2) 1-hydroxy-3,7,8-trimethoxy-xanthen-9-one,( 3) 1,5-dihydroxy-3,8-dimeth-xanthen-9-one,( 4) 1-hrdroxy-3,5,8-trimethoxy-xanthen-9-one,( 5) 1,3,5,8-tetrahydroxy-xanthen-9-one,( 6) 1,3,6,8-tetrahydroxy-xanthen-9-one,( 7) 1,3,6,7-tetrahydroxy-xanthen-9-one,( 8) 1,3,7-trihydroxy-xanthen-9-one,( 9) 1,4,6,8-tetrahydroxy-1,2,3,4-tetrahydro-xanthenes-9-one. |
