超临界二氧化碳萃取沙棘籽油的成分分析

 目的：分析用超临界二氧化碳提取所得沙棘籽油的化学成分。方法：采用气相色谱-质谱-计算机联用（GC-MS-DS)法，直接进样分析沙蛛籽油的游离成分；油中的脂肪酸含量系用水解-甲基化法处理后测定。结果：将沙棘 籽油直接进样，检出不饱和醛（15.23%)、维生素E类（10.46%)、香树脂醇类（2.55%)及甾醇类（27.23%)等。水解 -甲基化测出8种脂肪酸，其中不饱和脂肪酸相对含量高达90%。结论：用SFE法提取沙棘籽油供临床使用，不仅无 溶剂污染，而且产品的化学成分较全面地得以保留。

Chemical analysis of seed oil from Hippophae rhamnoides by carbon dioxide supercritical fluid extraction(SFE)

OBJECTIVE To analyse seed oil from Hippophae rhamnoides by carbon dioxide suppercritical fluid extraction (SFE). METHOD:GC-MS-DS system was used to analyse the seed oil of Hippophae rhamnoides L. extracted by SFE method.RESULTS: The oil is in rich unsaturated aldehyde(15.23%)、Vit E group(10.46%),five-ring triterpenes (amyrins，2.55%) and steroids etc. The unsaturated fat acids content are nearly 90% in its fat acids.CONCLUSIONSeed oil extracted from Hippophae rhamnoides by SFE,has no solvent contamination but total chemical conponents.
