Khayseneganins A–H, Limonoids from Khaya senegalensis

Journal of Natural Products, 2012
Eight new limonoids, khayseneganins A-H (1-8), and 31 known limonoids were isolated from the leaves and twigs of Khaya senegalensis. The structures of the new compounds were elucidated by 2D-NMR spectroscopy and mass spectrometry, and the absolute configuration of 1 was determined by the CD exciton chirality method.

Anticancer activity of limonoid from Khaya senegalensis

Phytotherapy Research, 2007
AbstractTwo limonoids were isolated from the methanol extract of Khaya senegalensis (Meliaceae), and their structures were identified as 3α,7α‐dideacetylkhivorin (1) and 1‐O‐acetylkhayanolide B (2) on the basis of MS and NMR spectral data. Complete assignments of 1H and 13C chemical shifts for compounds 1 and 2 were achieved by means of 1D and 2D NMR ...
