Abstract
New compound 1 (Gautin), a new flavone glycoside with a unique aglycone moiety, with five flavone, acacetin-7-O-β-Drutinoside 2, Tricin 3, Hispidulin 4, 3,5,7,8-tetra hydroxyl-6,3′dimethoxy flavones 5 and Pectolinarigenin 10 and also six terpenoids (25S)-spirostan-5-ene-3β-21-diol-3-O-α-L-rhamnopyranosyl-(1,2)-[α-L-rhamnopyranosyl-(1,4)]-β-D-glucopyranoside 6, Ursolic acid 7, Lantanilic acid 8, Icterogenin 9, Betulonic acid 11 and Betulinic acid 12 have been isolated from the dried leaves of Lantana camara L. The structure of compound 1 (Gautin) assessed by spectroscopial analysis as 5,7-dihydroxy-6,3′,4′trimethoxy isoflavone-5-O-α-L-rhamnopyrano-syl-7-O-β-D-arabinopyranosyl-(1→4)-O-β-D-xylopyranoside. Three flavones 1, 2, 5 and one terpenoid 11 are isolated for the first time from this plant.
