Role of virgin coconut oil (VCO) as co-extractant for obtaining xanthones from mangosteen (Garcinia mangostana) pericarp with supercritical carbon dioxide extraction

Antioxidant 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...

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...

Xanthones from the heartwood of Garcinia mangostana.

Twelve xanthones were isolated from the hexane extract of the heartwood of Garcinia mangostana from Myanmar. Their structures were determined using 1D and 2D NMR techniques

Vetiver Oil Extraction Optimization Using Supercritical Carbon Dioxide Fluid

Coupling Microwave-Assisted Drying and Supercritical Carbon Dioxide Extraction for Coconut Oil Processing

Supercritical carbon dioxide extraction was applied to the processing of virgin coconut oil (VCNO), which has been known to possess several functions such as antimicrobial properties as proven by many medical doctors and clinical researchers. Prior to extraction, the sample was dried using microwave-assisted low-temperature air drying method. Using these techniques, an oil recovery of 95% was o...
