Objective: This research was conducted to screen inhibition of HIV-1 reverse transcriptase activity of selected Indonesia medicinal plants and to isolate HIV-1 reverse transcriptase inhibitor from Erythrina variegata leaves. Method: Screening inhibition of HIV-1 RT activity of selected Indonesia medicinal plants and isolated compounds were performed using HIV-1 RT colorimetric assay. The isolation of HIV-1 reverse transcriptase inhibitor was conducted using chromatography technique. The isolated compound was determined based on the data of UV, IR spectrophotometry, MS, 1D and 2D NMR spectroscopy. Results: Beside that, in vitro study of the leaves methanolic extract exhibited inhibition against HIV-1 RT activity with percent inhibition of 97.64% at concentration of 5 mg/mL. Ethyl acetate fraction from the extract showed the strongest HIV-1 RT inbitory activity with IC50 of 429.28 µg/mL. Isolation the HIV-1 RT inhibitor from the fraction give compound 1. Conclusion: Erythrina variegata leave extract exhibited potent inhibition on HIV-1 RT activity. The isolated compound from the leaves was determined as apigenin-7-O-β-D-glucopyranoside and demonstrated HIV-1 RT inhibitory activity with the IC50 value of 100.59 µg/mL.
