女贞果实多糖提取工艺优选和种子油成分分析_林文群（GC） . The Optimum Preparation Procedure for the Extracting Polyhexose Contained in Ligustrum licidum Ait.Fruit and Composition Analysis of Its Seeds Oil

Abstract

The optimum preparation procedure for the content of polyhexose in Ligustrum licidum Ait. fruit and exocarp were studied by L_9 (3~4) orthogonal experimental design. The results showed that the influences on condensation of alcohol, the amount of water-adding, extraction temperature and extraction time on the content of polyhexose-extracting of the whole fruit and its exocarp were indistinctive relatively. The polyhexose-extracting is complete relatively by means of short-time, more times. The main constitutents of fatty oil were oleic acid (44.378%) , linonic acid(41.934%) , palmitic acid (4.525%) , stearic acid (1.843%) and linolenic acid (0.867%) etc. The content of unsatujrated fatty acids reached 87.179%, Its seed oil had higher nutrient value and had potential prospects in exploitation and utilization.
