【摘要】 以云南省4个县7个群体野生硬核(Scleropyrum wallichianum)99株树的种子为材料测定脂肪酸成分及含量,并进行变异分析。GC/MS检测结果表明,所有样品中都含有12类脂肪酸,其中十八碳炔酸(包括8-十八碳炔酸、9-十八碳炔酸)的相对含量最高,变幅为23.47%~72.60%,平均值为41.40%;十八碳烯酸[油酸,18∶1(9)]含量变幅为11.18%~24.12%,平均值为17.24%;十八碳酸总含量为40.82%~89.76%,平均值为62.08%。脂肪酸相对含量在群体内部变异大,而在群体间的变异小。更多还原

【Abstract】 In order to explore the population variation pattern of fatty acids fromScleropyrum wallichianum seeds,the sample seeds of 99 wild individuals from 7populations in 4counties of Yunnan were collected.The components and the percentage of fatty acids of all sample seeds were analyzed.Twelve kinds of fatty acids were detected from all 99 sample seeds simultaneously.The total percentages of 8-octadecynoic acid and 9-octadecynoic acid ranged from 23.47%to 72.60%,with an average of 41.40%,and oleic acid percentage ranged 11.18% to 24.12%,average 17.24%,and 18 Cfatty acids percentage ranged from40.82% to 89.76%,average 62.08%.The variation of individuals in population was much larger than that of among populations.更多还原
