摘要
采用气相色谱-质谱联用法(GC-MS),分析了4种不同成熟期的花椒籽油中的脂肪酸成分.结果表明:不同成熟期花椒籽油中共有17种化合物得到鉴定,主要为反式-油酸(43.07%~47.94%)、亚油酸(15.52%~32.75%)、正十六烷酸(15.30%~22.96%).聚类分析结果表明,4种不同成熟期的花椒可聚为2组,成熟期较晚的2种花椒‘八月椒,和‘二红袍’为一组,而成熟期较早的2种花椒‘大红袍’和‘梅花椒’聚为另一组.对4种花椒籽油的品质评价结果表明,相对于成熟期较早的‘大红袍’和‘梅花椒’,成熟期较晚的‘八月椒’和‘二红袍’评价较优.
The fatty acids in four prickly ash seed oil were analyzed by GC-MS. 17 fatty acids were iden tiffed,and main compositions were trans-oleic acid (43.07%-47.94%), linoleic acid (15.52%-32. 75%) and n-hexadecane acid (15. 30%-22. 96%). Cluster analysis of the percentage composition of 17 compounds showed differences in chemical composition which were related to the maturity. The quality evaluation of four prickly ash seed oil showed ‘Bayuejiao' and ‘Erhongpao' had better than ‘Dahongpao' and ‘ Meihuajiao'.
