Phytochemical constituents identification from bark of garcinia mangostana

Garcinia mangostana is a species from the family Guttiferae (Clusiaceae) which comprises of about 50 genera and nearly 1200 species that can be found mainly in tropics as tropical trees, climbers or herbs. The species have sticky yellow gum resin. Garcinia mangostana can be found planted in tropical countries such as Northern Australia, South America and tropical Africa. However, the main distribution of this species is in South-eastern Asia, specifically, Malaysia, Thailand, Philippines and Indonesia. Due to the chemical constituents within them which are mainly flavonoids, the Garcinia species have a wide variety of biological properties including anti­ inflarnmatory, antifungal, antiviral, antiallergic, anticancer, antioxidant, antimalarial and antituberculosis. A study on the bark of Garcinia rnangostana was done to extract, isolate and identify phytochemical compounds of the species. The bark of Garcinia rnangostana was extracted using methanol. The methodologies include cold extraction, thin layer chromatography (TLC) and spectroscopy. Several compounds were isolated in this research and peaks were obtained from 1HNMR but were insufficient to elucidate the structures of the compounds. Therefore, more research is required to further elucidation of the compounds.
