【目的】对不同居群大花黄牡丹油脂成分进行评价，揭示该种是否适合作为油用牡丹开发的新材料。【方法】使用气质联用色谱法（GC-MS）对采自西藏林芝和山南地区5个居群的混合种子以及2个居群的单株进行了油脂成分分析。【结果】大花黄牡丹籽油富含不饱和脂肪酸（86．32％），油酸＞α-亚麻酸＞亚油酸；林芝地区4个居群油脂成分接近，各脂肪酸成分显著高于山南居群；居群内单株油脂成分林芝1号居群内部无差异，山南居群内部差异明显。【结论】野生大花黄牡丹油脂成分和组成与其他栽培种油用牡丹差异较大，油酸含量较高，亚麻酸含量较低，更有利于保存，大花黄牡丹可以作为油用牡丹开发的新材料。

[Objective]The aim of the study was to analyze seed oil composition of different popu-lations of Paeonia ludlowii and to assess whether this species is a suitable material for developing oilseed peony or not.[Method]A total of five populations (No.1-5)were collected in Nyingchi Prefecture and Lhoka of Tibet.Oil composition analysis based on GC-MS was performed for seed mixtures of five populations and individual plant of two populations.[Results]P .ludlowii seed oil was rich in unsaturated fatty acids (86.32%)and the order was oleic acid >α-linolenic acid >linloeic acid.Four populations in Nyingchi had a similar oil composition,with fatty acids signifi-cantly being higher than those of population in Lhoka Prefecture.In terms of oil composition of individual plants,No.1 population in Nyingchi had no internal differences whereas the population in Lhoka had obvious internal differences.[Conclusion]There were significant differences in com-position oleic acid content between cultivated oil seed and peony P .ludlowii.The seeds with higher oleic acid content and lower linloeic acid content were favorable for preservation.P .lud-lowii can be used as a suitable material for developing oilseed peony.
