Anti-HIV-1 protease activities of crude extracts of some <i>Garcinia</i> species growing in Tanzania
Abstract
Eighteenth ethanol extracts from some Garcinia species in the Guttiferae (Clusiaceae) family collected in Tanzania were investigated for their HIV-1 protease (HIV-1 PR) inhibitory activities using high performance liquid chromatography (HPLC). Among the tested extracts, the fruit hulls of Garcinia
semseii showed the most potent inhibitory activity against HIV-1 PR with an IC50 value of 5.7 ìg/ml followed by the stem bark extracts of Garcinia edulis and Garcinia kingaensis with IC50 values of 9.2 and 15.2 ìg/ml, respectively. Phytochemical screening of extracts indicated mostly the presence of phenolic
and steroidal compounds.
