| 中文摘要: |
| 分析11省（市）18个产地不同种源预知子籽的油脂含量，通过气相色谱-质谱联用仪分析其油脂脂肪酸组成，并采用欧氏距离、ward法进行聚类分析，为更好地筛选和培育优良油用预知子提供实验数据。结果表明：不同种源预知子籽的油脂含量在36.84%~48.68%之间；预知子籽油中脂肪酸均以不饱和脂肪酸为主，各脂肪酸的相对含量差异较大，其中油酸和亚油酸含量变化范围分别为21.09%~44.21%和18.43%~37.07%，除湖北襄阳预知子籽（三叶木通种子）油未检出亚麻酸外，其他地区亚麻酸含量变化范围为2.55%~24.63%；聚类分析将预知子分为4类。表明不同种源预知子营养价值存在差异。 |
| 英文摘要: |
| The oil content of Akebiae Fructus seed of different provenances from 18 producing areas in 11 provinces or cities was analyzed and the oil fatty acid composition was analyzed by gas chromatography-mass spectrometry, and the Euclidean distance and ward method were used for cluster analysis in order to provide scientific basis for selecting and breeding oil Akebiae Fructus. The results showed that the oil content of Akebiae Fructus seed from different provenances was 36.84%-48.68%. All Akebiae Fructus seed oil was rich in unsaturated fatty acids but the contents of different fatty acids had great differences. The contents of oleic acid and linoleic acid were 21.09%-44.21% and 18.43%-37.07%, respectively, and the content of linolenic acid was 2.55%-24.63% except the Akebia trifoliate seed oil in Hubei Xiangyang. Cluster analysis divided the Akebiae Fructus into four categories. The nutritional value of Akebiae Fructus from different provenances was different. |
