ISOLATION AND CHARACTERISATION OF ALPHA AND BETA AMYRINS FROM PROPOLIS OBTAINED FROM BENUE STATE

Chemical composition of propolis has been reported to be phyto-geographical in nature. The aim this study was isolate and characterize chemical compounds from hexane ethyl acetate extract obtained Gboko. To compounds, subjected column chromatography by gradient elution using two solvent mixtures - hexane: acetate: methanol. structure the isolated compound established 1H-NMR further verification data on comparison with literature reports. α-amyrin, β-amyrin, α-amyrin β-amyrin acetate, known pharmacologically active pentacyclic triterpenoids, were propolis.
