BARRETO, Milena B. et al. Volatile and non-volatile chemical constituents of Moringa oleifera Lam., Moringaceae. Rev. bras. farmacogn. [online]. 2009, vol.19, n.4, pp.893-897. ISSN 0102-695X.

Phytochemical analysis of the ethanol extract from leaves of Moringa oleifera Lam., Moringaceae, yield the benzylnitriles: niazirine, niazirinine and 4-hydroxyphenylacetonitrile, while of fruit shells only octacosane was isolated. The essential oils from leaves, flowers and fruits were examined by gas chromatography-mass spectrometry. The major constituents identified were: phytol (21.6%) and thymol (9.6%) in the leaves oil, octadecane (27.4%) and hexadecanoic acid (18.4%) in the flowers oil, docosane (32.7%) and tetracosane (24.0%) in the fruits oil. The structures of all compounds were identified by spectroscopic analyses (NMR, IR and MS). 4-hydroxyphenylacetonitrile is reported for the first time to the Moringa genus and the essential oils of flowers and fruits are reported for the first time to the species M. oleifera.

Keywords : Moringa oleifera; Moringaceae; essential oils; nitriles; niazirine; niazirinine.
