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.
