Definition:An organic heterotetracyclic compound that is 9,9a-dihydro-9,4a-prop[1]enoxanthene-1,4-dione substituted by a hydroxy group at position 7, a methyl group at position 12 and a prenyl group at position 9a. Isolated from the root barks of Ehretia buxifolia, it exhibits antisnake venom activity.
