| مستخلص: | Paeonia ludlowii(PL) and oil-producing peony (OP) are unique peony species in China. Due to the high content of unsaturated fatty acids in PL seeds, it can be used as a new resource for OP. In this study, 137 compounds were identified in PL seeds in qualitative analysis by UPLC-Q-TOF–MS/MS, including flavonoids, terpenoids, fatty acid esters, phenolic acids, etc. Except for 5 fatty acids, the other components were first reported in the literature of PL. There were 26 components exist only in seed kernel, 21 components exist only in seed coat, and 90 components exist both in seed kernel and coat. 35 of 61 differential components were first reported in the peony literature, and these components were identified in the chemical difference analysis between seed kernel and coat of PL, seed kernel of PL and OP, and seed coat of PL and OP. Quantitative analysis manifested that the weight of palmitic acid, oleic acid and linoleic acid accounted for 60.7% in the seed kernel of PL, while the average content in that of OP was 46.7%. Among them, the content of linolenic acid was about 3 times higher. This study further clarified the material basis of PL seeds, and also analyzed the chemical differences between the seeds of PL and OP. It was confirmed from the chemical level that the seed oil in PL was better than that in OP. The results of this study laid a solid foundation for the subsequent development of new products of PL. |
