Characterization of oils and chemical analyses of the seeds of wild plants

Plant Foods Hum Nutr. 1994 Dec;46(4):361-5. doi: 10.1007/BF01088437.

Abstract

The Chemical compositions of the seeds of some wild plants have been investigated. The seeds of Hematostaphis berteri, Balanites aegytiaca and Ximenia americana contain high levels of oils with values in the range, 38.2-54.5% (w/w). The iodine values of the oils were determined and, for Ximenia americana, the value was high, i.e., 149.8 mg/100 g. The storage properties of the oil of Hematostaphis berteri were examined over a period of fifty six days by exposure to light at ambient temperature. The peroxide value of the oil over the period increased by 12-fold of its initial value of 27.5 mEq/kg, suggesting light susceptibility to photo-oxidative degradation. The proximate protein contents were low but the concentrations of mineral elements in the seeds examined were generally high, exceeding the values for the corresponding mesocarps by several orders of magnitude.
