22 个芍药品种种籽功能性成分分析.

22 peony cultivars were used as test material to investigate their traits such as kernel yield, seed oil yield, as well as the functional components in seed oil, seed cake and seed coat. The result showed the peony seed oil was extracted by supercritical fluid extraction instrument. Oil yield of the tested cultivars was 26. 62%-15. 96%, the average was 22. 12%. The analysis by gas chromatography-mass spectrometry (GC-MS) showed that fatty acids in peony seed oil were mainly oleic acid, linolenic acid, linoleic acid, stearic acid and palmitic acid. The total unsaturated fatty acids in the seed oil were more than 85%, with high nutritional value and health functions, which had the potential for exploitation. The content of total flavonoids, paeoniflorin and crude protein in the by-products of peony seed oil extraction were 7. 78 mg / g, 24. 85 mg / g and 16. 92%, respectively. The content of total flavonoids and resveratrol in the seed coat was 107. 30 and 3. 11 mg / g, respectively. In summary, seed cake and seed coat could be developed and utilized both as raw materials for functional nutritional health products, as well as used as new high nutrient feed, indicating that peony had high comprehensive utilization potential and could provide important reference for the development of related industries.
