An investigation of the composition of an ethereal extract of the fruit stones ofAnisophyllea laurina

It has been shown by the methods of IR and1H and13C NMR spectroscopy and also by spectrometry that ether extracts a fat from the kernels of the fruit stones ofAnisophyllea laurina (familyRhizophoraceae, Guinea). The amount of fat is about 16% of the weight of the kernels. The acid composition of the fat has been studied by gas chromatography and mass spectrometry. It contains the following acids (%): myristic (traces), palmitoleic (26.1), palmitic (54.4), linoleic (5.5), oleic (10.1), vaccenic (3.1), and stearic (0.8).
