Antioxidant and cytotoxicity activities of δ-tocotrienol from the seeds of .

Chemical investigation of P. Beauv fruits led to the isolation of a new -tocotrienol, 3-hydroxy-δ-tocotrienol () together with eight known compounds (-). Compound ( was allylated () and prenylated ( and ) to give three new semi-synthesized derivatives which were fully characterized as: 6--allyl-3-hydroxy-δ-tocotrienol (), 6--prenyl-3-hydroxy-δ-tocotrienol () and 6-,5-C-diprenyl-3-hydroxy-δ-tocotrienol ().

Phytochemical, antibacterial, antioxidant and cytoxicity investigation of .

The phytochemical investigation of led to the isolation of 18 known compounds of which were four flavones, three anthraquinones, one phenyl propanoic derivative, five triterpenoids, four steroids and a mixture of glucose. Luteolin () and soranjidiol () were allylated and/or prenylated to give four new semisynthesized derivatives which were fully characterized as 7,3',4'--triallylluteolin (), luteolin-7,3',4'--triprenyls (), luteolin-5,7,3',4'--tetraprenyls () and 6--allylsoranjidiol (). Their structures were established using spectroscopic analysis including 1D, 2D NMR and MS data.
