Chemical studies of the ethanol extracts of the seeds of Moringa oleifera Lam. yielded 4-(4'-O-acetyl-α-L-rhamnosyloxy)benzyl isothiocyanate (1), a mixture of 1 and 4-(3'-O-acetyl-α-L-rhamnosyloxy)benzyl isothiocyanate (2) in a 2:1 ratio, 4-(α-L-rhamnosyloxy)benzyl isothiocyanate (3), a mixture of 3 and niazimicin (4) in a 2.5:1 ratio, triolein (5), β-sitosteryl oleate (6), and a mixture of β-sitosterol (7) and stigmasterol (8) in a 4:1 ratio from the immature seeds; 3, 5, 6, a mixture of 7 and 8 in a 3:1 ratio, oleic acid (9), and 1-octadecene (10) from the mature seeds; and 5, a mixture of 7 and 8 in a 4:1 ratio, and 9 from the brown seeds. The major constituents of the immature seeds are the isothiocyanates 1 and 3, while the major constituents of the brown seeds are the lipids 5 and 9. The structures of 1-10 were identified by NMR spectroscopy. © 2016, International Journal of Pharmacognosy and Phytochemical Research. All rights reserved.
