Definition:An extended flavonoid that is flavonol with additional hydroxy groups at position 5 and 3', a 2,2-dimethyldihydropyrano ring fused to ring A across positions 7 and 8, a prenyl group at position 6 and a (2S)-2-hydroxy-3-methylbut-3-en-1-yl group at position 4'. Isolated from the roots of Dorstenia psilurus, it exhibits alpha-glucosidase inhibitory activity.
