Four New Anthraquinones with Histone Deacetylase Inhibitory Activity from Roots.

Chromatographic separation of the crude extracts from the roots of led to the isolation of four new anthraquinones, ventilanones L-O (-), together with eight known anthraquinones (-). Their structures were elucidated by spectroscopic methods (UV, IR, H NMR, C NMR, and 2D NMR) and mass spectrometry (MS), as well as comparison of their spectroscopic data with those reported in the literature. HDACs inhibitory activity evaluation resulted that compound exhibited moderate antiproliferative activity against HeLa and A549 cell lines but nontoxic to normal cell.

Phytochemicals from twigs of and their antioxidation kinetics of oxymyoglobin.

The phytochemical investigation of crude -hexane and ethyl acetate extracts from twigs of (Kurz) led to the isolation of 14 known compounds. Their structures were elucidated by spectroscopic techniques (IR, H NMR, C NMR, and 2D NMR) as well as mass spectrometry. These structures were characterized as -sitosterol (), lupeol (), vanilic acid (), 5,7-dihydroxychromone (), (+)-mellein (), isoliquiritigenin (), 7-hydroxyemodin (), physion (), aromadendrin (), naringenin (), apigenin (), luteolin (), chrysoeriol () and kaempferol ().
