摘要
为寻求新的食用油资源,发展了一种快速可靠的气相色谱-质谱联用方法,用于植物籽油中脂肪酸成分的定性鉴定和含量测定。所建立的方法成功用于葡萄籽、南瓜籽和猕猴桃籽等七种植物籽油中的棕榈酸、十八烷酸、油酸、亚油酸和α-亚麻酸的定性定量分析。结果表明,刺葡萄籽油、普通葡萄籽油、国外葡萄籽油、南瓜籽油、枸杞籽油和西番莲籽油均具有相似的脂肪酸谱,尽管其中它们所含上述五种脂肪酸含量不同,由于均存在人体所必需的饱和与不饱和脂肪酸,故可以用作替代食用油。猕猴桃籽油因为其存在高含量的α-亚麻酸成分,可能是更好的食用油和营养油资源。本文首次对枸杞籽油、西番莲籽油和猕猴桃籽油脂肪酸成分进行绝对含量分析,为新的食用油资源的开发提供了重要的依据。
To find new edible oil sources,a rapid and reliable gas chromatography mass spectrometry method for fatty acid identification and quantitation was developed.The proposed method was then used to quantitation of palmitic acid,stearic acid,oleic acid,linoleic acid and α-linolenic acid in seven different plant seend oils.The fatty acid profiles of spine grape seed,grape seed,foreign grape seed,pumpkin seed,barbary wolfberry fruit seed and passion flower seed oils are similar with different contents of the five fatty acids,indicating they can be alternative sources of edible oil due to the presence of all saturated and unsaturated fatty acids required for human health.Yangtao kiwifruit seed oil may be much better alternative source of edible and nutritional oil because of a high content of α-linolenic acid.This is the first research on the absolute content analysis of fatty acid composition of barbary wolfberry fruit seed oil,passion flower seed oil and yangtao kiwifruit seed oil which provides an important and scientific basis for new edible oil resource exploitation.
