采用气相色谱法对产自伊朗两个不同地区的25种石榴籽油的脂肪酸组成进行了定性和定量分析。籽油含量约为66.3 ~ 193 g kg(-1)，显著高于西方石榴品种。除了医疗用途和特殊消费外，脂质含量水平可能被认为不足以进行经济工业开发。前优势脂肪酸为亚麻酸（C18:3），含量为31.8 ~ 86.6%，其次为亚油酸（0.7 ~ 24.4%）、油酸（0.4 ~ 17.4%）、硬脂酸（2.8 ~ 16.7%）和棕榈酸（0.3 ~ 9.9%）。在部分品种中还发现了饱和肉豆蔻酸（0.1 ~ 4.7%）和脱酚酸（0.0 ~ 3.9%）。我们尚未证实在食用和非食用石榴品种中存在月桂酸、花生酸和木素酸。脂肪酸组成的品种间差异显示，它们可能有助于建立化学分类学差异。(c) 2004 Elsevier Inc.版权所有。
The fatty acids composition of the seed oils of 25 pomegranates varieties obtained from two different regions of Iran (Punica granatum L.) was qualitatively and quantitatively determined by gas chromatography. The seeds contained oil in the range of about 66.3-193 g kg(-1) dry matter, a notably higher content than western pomegranate cultivars. Levels of lipid content probably could be considered insufficient for economic industrial exploitation except for medical usages and specific consumption. The pre-dominant fatty acid was linolenic acid (C18:3) and its content was about 31.8-86.6%, followed by linoleic acid (0.7-24.4%), oleic acid (0.4-17.4%), stearic acid (2.8-16.7%), and palmitic acid (0.3-9.9%). To a lesser extent, the saturated myristic acid (0.1-4.7%) and behenic acid (0.0-3.9%) were also found in some cultivars. We have not confirmed the presence of lauric, arachidic and lignoceric acids previously reported in edible and non-edible pomegranate cultivars. Intervarietal differences in fatty acid compositions were shown and they could be useful to establish chemotaxonomic differences. (c) 2004 Elsevier Inc. All rights reserved.
