金樱子籽油的提取及其脂肪酸成分分析_李加友 . Extraction of Rosa Laevigata and Analysis of Its Fatty Acid Components

Abstract

The extraction and refinement of rosa laevigata's seed oil investigates the physicochemical properties of seed oil.The ingredients and contents of fatty acids in the seed oil are determined with GC-MS.The result shows that the oil yield of rosa laevigata's seed oil is 5.24%;the acid value is 0.36 mgKOH / g;the peroxide value is 46.10 mmol / kg;the iodine value is 160.90 gI2/100 g;and the saponification value is 193.76 mgKOH / g.Five fatty acids are identified in the rasa laevigata's seed oil.The content of unsaturated fatty acid is 86.10% which includes 43.99% linoleic acid and 42.11% α-linolenic acid.But the saturated fatty acid is 13.90% which is composed of palmitic acid,stearic acid and arachidic acid.The seed oil has plentiful unsaturated fatty acids and it is a potential source for nutritional and healthy functions.
