| 摘 要： | 目的]本文对芍药种子含油率、脂肪酸成分及含量进行了探讨,为芍药开发成油料植物提供参考。方法]选取芍药36个栽培品种和1个野生居群为样本,采用索氏提取法提取种子油脂并测定含油率,用气相色谱—质谱联用仪(GC-MS)对提取的籽油成分进行分析。结果]表明:芍药36个栽培品种和1个野生居群种子平均含油率为20.20%。芍药籽油主要含有豆蔻酸、棕榈酸、棕榈一烯酸、硬脂酸、油酸、亚油酸、亚麻酸和花生酸8种脂肪酸,其中,亚麻酸含量最高,平均达34.14%,其次为油酸和亚油酸,这3种不饱和脂肪酸的含量占全部脂肪酸的93.37%。芍药籽油脂肪酸含量变化相对稳定,各脂肪酸成分的变异系数从大到小依次为亚油酸(13.90%)油酸(13.51%)亚麻酸(10.71%)棕榈酸(0.18%)硬脂酸(0.09%)花生酸(0.002%)、棕榈一烯酸(0.002%)豆蔻酸(0.00%)。结论]芍药种子含油率高,富含亚麻酸、亚油酸和油酸,且含量相对稳定,变异很小,具有开发为高含量亚麻酸食用油潜力。

| Abstract: | Objective] To studying the seed oil content, fatty acid composition and content of Chinese herbaceous peony(Paeonia lactiflora), aiming at providing a theoretical basis for oil plant development. Method] 36 cultivars and 1 wild population of P. lactiflora were selected as samples, the seed oil were extracted and the oil content was determined by Soxhlet Extraction Technology, and the components of the seed oil was analyzed with Gas Chromatography-Mass Spectrometry(GC-MS). Result] The average oil content of peony seeds was 20.20%. The seed oil mainly contained eight fatty acids, viz. myristic, palmitic, palmitoleic, stearic, oleic, linoleic, linolenic and arachidic, among which the main fatty acids were linolenic acid (up to 34.14%), followed by oleic acid, linoleic acid and palmitic acid. These three kinds of unsaturated fatty acids account for 93.39% of total fatty acids. The variation of fatty acid content was relatively stable, and the variation coefficients were 13.90%(linoleic acid), 13.51%(oleic acid), 10.71%(linolenic acid), 0.18%(palmitic acid), 0.09(stearic acid), 0.002%(arachidic acid), 0.002%(palmitoleic acid) and 0.00%(myristic acid).Conclusion] Chinese herbaceous peony seeds not only have high oil content, but is also rich in linolenic, linoleic and oleic acids. The content of these fatty acids is relatively stable with only small variations. The research provides evidence for the development of Chinese herbaceous peony as oil plant with high linolenic acid content. |
