| 摘 要： | 运用正交实验L9（3^4)对女贞全果及外果皮的多糖提取工艺进行优选。结果表明所选4个因素（乙醇体积分数、加水量、加热温度和提取时间）对全果和外果皮多糖提取的影响相对不显著，采用短时多次提取，多糖提取比较完全。种子油脂肪酸的主要成分为：油酸（44．378％）、亚油酸（41．934％）、棕榈酸（4．525％）、硬脂酸（1．843％）和亚麻酸（0．867％）等，种子油不饱和脂肪酸的含量达87．179％，具有较高营养价值和开发利用前景。 |

| Abstract: | The optimum preparation procedure for the content of polyhe xo se in Ligustrum licidum Ait. fruit and exocarp were studied by L 9(34) o rthogonal expe rimen tal design. The results showed that the influences on condensation of alcohol, t he amount of water-adding,extraction temperature and extraction time on the co n tent of polyhexose-extracting of the whole fruit and its exocarp were indistinc t ive relatively. The polyhexose-extracting is complete relatively by means of s ho rt-time,more times. The main constitutents of fatty oil were oleic acid(44.37 8%) , linonic acid(41.934%), palmitic acid(4.525%), stearic acid(1.843%) and li nolen ic acid(0.867%) etc. The content of unsaturated fatty acids reached 87.179% , Its seed oil had higher nutrient value and had potential prospects in exploitation and utilization. |
| Keywords: | Ligustrum licidum Ait fruit polyhexose extraction condition seed oil composition of fatty acids |
