dc.description.abstract Several naturally occurring ursane or oleane-skeleton pentacyclic triterpenoids occur in a free form as aglycones or in combined forms in medicinal plants. Purification of ethylacetate soluble extract of Eucalyptus grandis leaves through combination of chromatographic techniques led to isolation of two pure compounds. The two isolates were characterized using UV, IR,1H, 13C, DEPT spectroscopic experiments, and in comparison with literature identified as 3β-hydroxyl-urs-12-en-3-ol (α-Amyrin) and as 3β, 28-dihydroxyl-12-ursen (Uvaol) respectively. Triterpenes have been reported in Eucalyptus species, but this is the first report on isolation and characterization of Amyrin and Uvaol in Eucalyptus grandis. en_US
