摘要: 为探讨贵州省不同地区牡丹子油品质的差异性,选取具有代表性的10个地区,采用压榨法提取牡丹子油。对牡丹子含油率、理化指标、多酚、微量元素及脂肪酸进行分析。结果表明,产地对牡丹子油的理化指标(相对密度、酸价、皂化值等)影响较小,对含油率、Fe、Cu、Zn、Ca元素及脂肪酸含量影响较大,其中,样品MDY4含油率最高,为33.75%,Fe、Cu、Zn 3种元素含量分别为9.42、4.29、55.04 mg/kg,油酸和α-亚麻酸含量分别为116.25和150.39 mg/g,在所有样品中含量最高。样品MDY1仅次于MDY4,因此,毕节市赫章县、铜仁市思南县可以作为油用牡丹(Paeonia suffruticosa Andr.)的推广种植及品种的选育产地。

Abstract: In order to explore the differences in the quality of peony seed oil in different regions of Guizhou Province, 10 representative regions were selected and peony seed oil was extracted by pressing method. The oil content, physicochemical indicators, polyphenols, trace elements, and fatty acids of peony seeds were analyzed. The results showed that the origin had little effect on the physicochemical indicators (relative density, acid value, saponification value, etc.) of peony seed oil, but had a significant impact on the oil content, Fe, Cu, Zn, Ca elements, and fatty acid content. Among them, sample MDY4 had the highest oil content at 33.75%, with Fe, Cu, and Zn elements at 9.42, 4.29, and 55.04 mg/kg, respectively. The content of oleic acid and α-linolenic acid was 116.25 and 150.39 mg/g, respectively, which was the highest among all samples. Sample MDY1 was second only to MDY4. Therefore, Hezhang County in Bijie City and Sinan County in Tongren City could be used as promotion planting areas and breeding areas for oil peonies.
