用索氏提取法获得牡丹籽油,经皂化、甲酯化后用毛细管GC-MS法对其脂肪酸成分进行分析,面积归一化法计算相对含量,同时按国家标准对牡丹籽油的理化指标进行了检测.结果表明,牡丹籽油中共有17种脂肪酸成分,主要为亚麻酸、油酸、亚油酸等,不饱和脂肪酸占83.05%,饱和脂肪酸占14.33%;牡丹籽油的酸值(KOH)为1.784 mg/g,碘值(I)为176.2 g/100 g,皂化值(KOH)为194.4 mg/g,相对密度0.930 7.说明牡丹籽是一种良好的油料资源,适宜开发利用.

The peony seed oil was obtained by Soxhlet extraction.After saponification and esterification of the oil,the fatty acid composition was determined by capillary GC-MS,and the relative contents were determined by peak area normalization.The physicochemical index of peony seed oil was analyzed by state standard method.The results showed that 17 fatty acids were identified,and the major fatty acids were linolenic acid,oleic acid and linoleic acid.The content of unsaturated fatty acids was 83.05%,and that of saturated fatty acids was 14.33%.The physicochemical indexes of peony seed oil were as follows:acid value 1.784 mgKOH/g,iodine value 176.2 gI/100 g,saponification value 194.4 mgKOH/g, relative density 0.930 7.The peony seed was a new oil resource containing rich linolenic acid.
