Anti-HIV components of TXE and VAD extracts. Jurkat cells were infected with HIV-1 HXB2 and then exposed to 10 μg/ml TXE (A), VAD (B), or each of its partition subfractions from petroleum ether (PE), chloroform (CF), ethyl acetate (EA) and n-butanol (BT) 24 hr post infection. Fresh extracts or subfraction were added every other day. Meanwhile, culture supernatants were collected for the RT activity assay, and aliquots of cells were stained with trypan blue dye and counted for viable cells. DMSO was the solvent of the extracts and subfractions and included as a vehicle control. The RT data from the supernatants collected at day 9 of the peak viral replication were presented. Extracts and their subfractions showed no apparent cytotoxic effects on the cells. The data were mean ± SEM of triplicate experiments.
