From the twigs of Myrica cerifera L. (Myricaceae), a new oleanane triterpenic acid named myrica acid was isolated along with myricalactone and several other known constituents. The structure of the acid was determined as 3β-hydroxy-1-oxoolean-11, 13(18)-dien-28-oic acid on the basis of chemical and spectral evidence.
