摘要:

以省沽油野生和栽培种子为材料,采用常规分析方法和GC-MS联用仪,对其种子出仁率、出油率、种子油脂肪酸组成与含量、油脂理化特性进行系统研究。结果表明:省沽油种子出仁率为49.78%~51.90%,种子出油率为27.82%~32.72%,属于高含油量种子;种子油不饱和脂肪酸总量为70.2%~80.3%,其中多不饱和脂肪酸(PUFA)占59.4%~67.7%,n6 PUFA/n3 PUFA为5.2~6.2,SFA∶MFA∶PUFA为1∶ (0.4~0.9)∶(0.8~6.6);种子油脂具有酸值和过氧化值较低的特点,属于亚麻酸类油脂。省沽油是一种很好的木本油料树种,可用来开发功能性植物油脂。

Abstract:

The composition and content of fatty acids, yield and physicochemical properties of wild and cultivation seeds of Staphylea bumalda seed oil were systematically measured with the routine analysis methods and GC MS in order to understand the characteristics and nutritional value of the oil. The results indicated that the kernel yield and oil yield of seeds were 49.78%~51.90% and 27.82%~32.72%, respectively, which belonged to high oil content. The total content of unsaturated fatty acids (UFA) and polyunsaturated fatty acids (PUFA) were 70.2%~80.3% and 59.4%~67.7% in fatty acids, respectively. The ratios of n6 PUFA/n3 PUFA and SFA∶MFA∶PUFA were 5.2~6.2 and 1∶ (0.4~0.9)∶ (0.8~6.6), respectively. The seed oil, belonged to linolenic acid type, had characteristics of low acid value (AV) and low peroxide value (POV). S.bumalda, a good kind of woody oil plant, can be used to exploit functional plant lipid.
