The hexane-extracted oil content of Moringa oleifera seeds ranged from 38.00 to 42.00%. Protein, fiber, and ash contents were found to be 26.50-32.00, 5.80-9.29, and, 5.60-7.50%, respectively. Results of physical and chemical parameters of the extracted oil were as follows: iodine value, 68.00-71.80; refractive index (40 degrees C), 1.4590-1.4625; density (24 degrees C), 0.9036-0.9080 mg/mL; saponification value, 180.60-190.50; unsaponifiable matter, 0.70-1.10%; and color (1 in. cell), 0.95-1.10 R + 20.00-35.30 Y. Tocopherols (alpha, gamma, and delta) in the oil were up to 123.50-161.30, 84.07-104.00, and 41.00-56.00 mg/kg, respectively. The oil was found to contain high levels of oleic acid (up to 78.59%) followed by palmitic, stearic, behenic, and arachidic acid up to levels of 7.00, 7.50, 5.99, and 4.21%, respectively. The induction period (Rancimat, 20 L/h, 120 degrees C) of the crude oil was 9.99 h and reduced to 8.63 h after degumming. Specific extinctions at 232 and 270 nm were 1.70 and 0.31, respectively. Many parameters of M. oleifera oil indigenous to Pakistan were comparable to those of typical Moringa seed oils reported in the literature. The results of the present analytical study were also compared with those of different vegetable oils.
辣木籽的正己烷提取物含油量在38.00%至42.00%之间。蛋白质、纤维和灰分含量分别为26.50 - 32.00%、5.80 - 9.29%和5.60 - 7.50%。提取油的物理和化学参数结果如下：碘值为68.00 - 71.80；折射率（40℃）为1.4590 - 1.4625；密度（24℃）为0.9036 - 0.9080毫克/毫升；皂化值为180.60 - 190.50；不皂化物为0.70 - 1.10%；颜色（1英寸比色槽）为0.95 - 1.10R + 20.00 - 35.30Y。油中的生育酚（α、γ和δ）含量分别高达123.50 - 161.30、84.07 - 104.00和41.00 - 56.00毫克/千克。该油中油酸含量较高（高达78.59%），其次是棕榈酸、硬脂酸、山嵛酸和花生酸，含量分别高达7.00%、7.50%、5.99%和4.21%。原油的诱导期（Rancimat法，20升/小时，120℃）为9.99小时，脱胶后降至8.63小时。在232和270纳米处的比消光值分别为1.70和0.31。巴基斯坦本土辣木油的许多参数与文献中报道的典型辣木籽油参数相当。本分析研究的结果也与不同植物油的结果进行了比较。
