Background: Garcinia is a tropical plant that grows in Indonesia. Garcinia has many health benefits for the body. Garcinia contains many phenolic compounds and their derivatives, such as xanthon, flavonoids, benzophenone, lactone, and phenolic acids. Garcinia fruticosa Lauterb. comes from the family Clusiaceae. The results of the phytochemical examination showed that G. fruticosa bark extract contained alkaloids, flavonoids, glycosides, tannins, and saponins. Objective: This study aims to isolate and identify chemical compounds from the ethyl acetate extract of G. fruticosa Lauterb stem bark. Method: G. fruticosa Lauterb bark. dried, milled, and extracted with Step Gradient Polarity/SGP maceration using n-hexane, ethyl acetate, and methanol. Isolation was done by column chromatography and identified by thin layer chromatography and IR spectroscopy, LC-MS/MS, 1H-NMR, 13C-NMR, 2D-NMR (HSQC, HMBC). Results: Compound D7a has a molecular weight 168.0496. The IR spectrum shows the presence of a group {\textendash}OH appears on 3483 cm-1, aromatic presence in 1609 cm-1. The H-NMR spectrum shows the presence of aromatic signals on 6.96 (d, 8 Hz), 6.96 (d, 2 Hz) and 7.70 (dd, 8; 2 Hz). The C-NMR spectrum shows the presence of a carboxylic-COOH group appearing at 166.57 ppm, the presence of 2 x C-OH appearing at 147.18 and 151.18. In the HMBC spectrum, the -OCH3 position is located at C-3 with a correlation between the 3.79 (s) signal and the C signal at the chemical shift 147.18. Conclusions: Structural elucidation shows that compound D7a is a 4-hydroxy-3-methoxy benzoate acid (Vanylic Acid) and isolate I-1 is an impure compound namely β-Sitosterol and Stigmasterol.

Background: AIDS in humans, which is caused by the HIV remains among the leading causes of death worldwide. Objective: The study was undertaken to investigate the HIV-RT inhibitory activity of Phytotesrols extracted from roots of Aerva lanata. Methodology: Sequential maceration method was performed for preparation of extracts using hexane, chloroform, ethyl acetate, acetone and methanol solvents. RetroSys HIV-1 RT (Innovagen, Sweden) kit was used to determine the HIV-RT inhibitory activity of all solvents extracts. Results \& Discussion:\ All extracts showed significant inhibitory activity. Chloroform extracts shows highest inhibition of recombinant HIV-RT (89.0\%) at 2 and mg/ml concentration. Phytosterols isolated from chloroform extracts. These results were remarkable and can be used to develop a new drug for HIV treatment or other infectious diseases caused by the pathogenic micro-organisms, for which plant sterols may play a distinctive role. Conclusion: Further work is in progress to evaluate the advanced spectroscopic studies are required for the structural elucidation, identification and characterization of the active compound from this plant.
