Xanthones from the Pericarp of Garcinia mangostana.
Mangosteen (Garcinia mangostana L.) is one of the most popular tropical fruits (called the "Queen of Fruits"), and is a rich source of oxygenated and prenylated xanthone derivatives. In the present work, phytochemical investigation has resulted in one new prenylated xanthone and 13 known xanthones isolated from the pericarp of G. mangostana. Their structures were established by spectroscopic da...
متن کاملAntioxidant xanthones from the pericarp of Garcinia mangostana (Mangosteen).
As part of ongoing research on cancer chemopreventive agents from botanical dietary supplements, Garcinia mangostana L. (commonly known as mangosteen) was selected for detailed study. Repeated chromatography of a CH2Cl2-soluble extract of the pericarp led to the isolation of two new highly oxygenated prenylated xanthones, 8-hydroxycudraxanthone G (1) and mangostingone [7-methoxy-2-(3-methyl-2-b...
متن کاملA new xanthone from the pericarp of Garcinia mangostana.
A new prenylxanthone, garcimangostanol (1), was isolated from the EtOAc-soluble partition of the ethanol extract of the pericarp of Garcinia mangostana L., along with three known compounds, namely 8-deoxygartanin (2), 1-isomangostin (3), and garcinone C (4). The structure of compound 1 was elucidated on the basis of its 1D, 2D NMR and MS data. Compounds 1-4 exhibited either significant o r mode...
متن کاملExtraction of Fucoxanthin from Raw Macroalgae excluding Drying and Cell Wall Disruption by Liquefied Dimethyl Ether
Macroalgae are one of potential sources for carotenoids, such as fucoxanthin, which are consumed by humans and animals. This carotenoid has been applied in both the pharmaceutical and food industries. In this study, extraction of fucoxanthin from wet brown seaweed Undaria pinnatifida (water content was 93.2%) was carried out with a simple method using liquefied dimethyl ether (DME) as an extrac...
متن کاملAssay-guided fractionation study of alpha-amylase inhibitors from Garcinia mangostana pericarp.
Alpha-amylase inhibitor (alpha-AI) activity of Garcinia mangostana, commonly known as mangosteen, pericarp extracts was studied by assay guided fractionations from lipophilic to hydrophilic using combined solvent extraction and Amberlite XAD2 adsorption chromatography. Neither the lipophilic, xanthone containing fraction, nor the highly polar fraction, which has no affinity on Amberlite XAD2, s...
