Chemical Characterization of Prickly Pear Seed Oil,Opuntia ficus‐indica

摘要

ABSTRACTOil extracted fromOpuntia ficus‐indicaseeds constituted 13.6 of the whole seed. Results of the physical and chemical analyses of the oil for refractive index, iodine number, saponification number, Reichert‐Meissl number, Hehner value, acid value and unsaponifiable matter compared well with the characteristics of other commonly consumed vegetable oils. Thin‐layer chromatography in conjunction with gas‐liquid chromatography‐mass spectrometry revealed a relatively high degree of unsaturation, 82, with a linoleic acid content of 73.4 followed by palmitic, 12, oleic 8.8 and stearic acid, 5.8. Based on these results,Opuntia ficus‐indicaseed oil appears to be a good potential source of edible oil for human and/or animal
