Chemical constituents of Garcinia mangostana pulp and seeds
Chemical investigation of the dichloromethane extracts of the freeze-dried Garcinia mangostana Linn. led to the isolation of δ-tocotrienol (1), α-mangostin (2), 3-isomangostin (3), stigmasterol (4), triacylglycerols (5), a mixture of β-sitosteryl-3β-glucopyranoside-6′-O-fatty acid esters (6a) and st...

| Summary: | Chemical investigation of the dichloromethane extracts of the freeze-dried Garcinia mangostana Linn. led to the isolation of δ-tocotrienol (1), α-mangostin (2), 3-isomangostin (3), stigmasterol (4), triacylglycerols (5), a mixture of β-sitosteryl-3β-glucopyranoside-6′-O-fatty acid esters (6a) and stigmasteryl-3β-glucopyranoside-6′O-fatty acid esters (6b) in about 3:2 ratio, from the pulp; and 4, 5, and linoleic acid (7) from the seeds. The structure of 1 was elucidated by extensive 1D and 2D NMR spectroscopy. The structures of 2-7 were identified by comparison of their NMR data with literature data. © 2016, International Journal of Pharmaceutical and Clinical Research. All rights reserved. |
