The escalation of infections caused by M. tuberculosis, particularly those caused by MDR-TB strains is of considerable global concern. Since no new antituberculosis drugs have become available during the last forty years, there is obvious need for new and effective anti-tubercular drugs. There are reports of phytochemical analysis of essential oils, glycolipids, sesquiterpenoids, triterpenoids ...
Kulit buah manggis ( Garcinia mangostana L ) merupakan tanaman yang cukup populer di Indonesia. Ekstrak kulit memiliki kandungan alpha mangostin. Berdasarkan penelitian senyawa tersebut aktivitas sebagai antibakteri Staphylococcus aureus . tingkat kelarutan rendah sehingga efektivitasnya tidak maksimal. Formulasi dalam bentuk SNEDDS diharapkan dapat meningkatkan daya dan bioavailabilitas dari e...
The present study involves the optimization of different solvent extract and Standardization of α-mangostin from fruit hulls of Garcinia mangostana was studied by gradient reverse-phase high-performance liquid chromatographic (HPLC) method for quality control and quantity determination. Chromatographic separation was carried out on Develosil RP C-18 (5 μm, 4.6 x 150mm) at room temperature using...
Calcineurin (CN), a unique protein phosphatase, plays an important role in immune regulation. In this study we used CN as a target enzyme to investigate the immunosuppressive properties of a series of natural compounds from Garcinia mangostana L., and discovered an active compound, isogarcinol. Enzymatic assays showed that isogarcinol inhibited CN in a dose-dependent manner. At concentrations r...
We purified and identified eight xanthones from mangosteen (Garcinia mangostana L.) and investigated whether these compounds inhibited the activities of mammalian DNA polymerases (Pols) and human DNA topoisomerases (Topos). β-Mangostin was the strongest inhibitor of both mammalian Pols and human Topos among the isolated xanthones, with 50% inhibitory concentration (IC50) values of 6.4-39.6 and ...
The present study is an attempt to evaluate the standardization of crude mangosteen and γ – mangostin from Garcinia mangostana on MCF-7 (breast cancer cell line) and Hep2 (laryngeal cancer cell line). The study includes cell doubling time, ED50 analysis (growth inhibition), cell proliferation assay and assessment of cell cytotoxicity by dye exclusion assay. The result of the study showed that t...
The little fire ant, Wasmannia auropunctata (Roger) (Hymenoptera: Formicidae), is an invasive ant that forms supercolonies when it successfully invades new areas. W. auropunctata was first reported in Hawaii in 1999, and it has since invaded a variety of agricultural sites, including nurseries, orchards, and pastures. Amdro (hydramethylnon; in bait stations), Esteem (pyriproxyfen; broadcast bai...
The xanthones α-mangostin and γ-mangostin are the major bioactive compounds in Garcinia mangostana (mangosteen) fruit extracts. Previously, we reported the pharmacokinetic properties of α-mangostin in rats. The purpose of this follow-up study was to compare the pharmacokinetic characteristics of α-mangostin and γ-mangostin in rats if administered as either a pure compound or as a component of a...
Cancer chemoprevention is a promising strategy taken to block, reverse, or retard carcinogenesis. α-Mangostin, a natural xanthone isolated from the pericarps of mangosteen, represents one of the most studied chemopreventive agents. This compound has been reported to interfere with all the major stages of carcinogenesis: initiation, promotion, and progression. A number of mechanisms have been pr...
