| 中文摘要: |
| 以我国北部、中部、南部的脱皮、未脱皮（包括由康莱特公司提供的未脱皮薏苡仁）8种薏苡仁为原料，对其油脂中甘油酯、脂肪酸、甘油三酯、生育酚、角鲨烯和甾醇组成进行了分析比较。结果表明：首次在薏苡仁油中发现了25-羟基-24-甲基胆固醇、（3α)-豆甾-7,24(28)-二烯-3-醇和（3α，5α）-豆甾-3-醇；康莱特公司提供的未脱皮薏苡仁中活性物质PLO与OLO的总含量最高；薏苡仁油中含有丰富的不饱和脂肪酸，其UFA与SFA的比值（5.06～6.62）接近于橄榄油（4.57～5.83）；薏苡仁油中角鲨烯和甾醇含量（5.13～8.30 mg/g）和生育酚含量（0.64～1.57 mg/g）也比橄榄油（0.96～1.79 mg/g、0.26～1.0 mg/g）的高；表明薏苡仁油是具备较大开发潜力的健康油脂。 |
| 英文摘要: |
| Eight kinds of coix seeds with or without peel(including coix seeds without peel from Kanglaite corporation) were collected from northern, central and southern China, and the possible bioactive chemical compositions including sterols, tocopherols, squalene, triglyceride, fatty acid and glyceride in the coix seed oils（CSOs） were determined. The results showed that 25-hydroxy-24-methylcholesterol,(3α)-stigmasta-7,24(28)-dien-3-yl and(3α,5α)-stigmastan-3-yl were first found in CSOs. The active substance total content of PLO and OLO in coix seed from Kanglaite corporation was the highest. CSOs were rich in unsaturated fatty acids and the ratio of UFA to SFA was between 5.06 and 662, close to that of olive oil(4.57-5.83). Also, CSOs contained abundant bioactive substances such as sterols and squalene(5.13-8.30 mg/g) and tocopherols(0.64-1.57 mg/g),higher than those in olive oil(0.96-1.79 mg/g, 0.26-1.0 mg/g), thus CSO could be considered as a potential source of oil with health-enhancing value. |
