Abstract: Eight compounds have been isolated from the aerial part of Ervatamia dwaracata (L.) Burk. Their chemical structures have been identified as cycloart - 23 - ene - 3β, 25 - diol (1), 3β - hydroxycy-cloart-25-ene-24-one (2) and cycloeucalenol (3), β - sitosterol, 3β - amyrin acetate, daucos-terol, ervatamine (4), tabemeamontanine (5) on the basis of spectral evidence. Three cycloartanes, cy-cloart - 23 - ene - 3, 25-diol (1), 3-hydroxycycloart-25-ene-24-one (2) and cycloeucalenol (3), are reported for the first time from the genus Ervatamia.

Key words: Ervatamia divaracata
