采用GC-MS和微波消解ICP-MS技术分别对野生和种植翅果油树果仁中脂肪酸及叶子、果皮、果壳和果仁中硒、镍、砷、铬、锡、铅、镉、汞8种微量元素进行了分析研究。结果表明,野生和种植翅果油所含脂肪酸均为8种,其中不饱和脂肪酸均为5种,油酸和亚油酸含量最高,分别占不饱和脂肪酸总量的93.30%和91.67%;油酸的含量是种植略大于野生,而亚油酸和亚麻酸的含量是野生略大于种植。2种翅果油树果仁、叶子、果皮及果壳中均含硒、镍、砷、锡、铅、镉和汞,但果仁和果壳中不含铬;硒主要分布在果仁、叶子和果皮中,而镍、砷、铬、铅、镉和汞主要分布在叶子和果皮中,其中镍和铅的含量较高;除果壳外,其他部位各元素的含量均是野生大于种植。
The content of selenium, nickel, arsenic, chromium, tin, lead, cadmium and mercury in the fatty acids, foliage, pericarp, shell and nuts of wild and planted Oleanolicornis were determined by GC-MS and microwave digestion ICP- Eight kinds of trace elements were analyzed. The results showed that there were 8 kinds of fatty acids in wild and sage oil, including 5 kinds of unsaturated fatty acids, the highest content of oleic acid and linoleic acid, accounting for 93.30% and 91.67% of the total amount of unsaturated fatty acids respectively. The acid content is slightly greater than that of the wild, while the content of linoleic and linolenic acid is slightly greater than that of the wild. The contents of selenium, nickel, arsenic, tin, lead, cadmium and mercury in nuts, leaves, peels and nutshells of two species of samara, but not in nuts and husks. Selenium mainly distributed in nuts and leaves And peel, while nickel, arsenic, chromium, lead, cadmium and mercury were mainly distributed in the leaves and peels, with a higher content of nickel and lead. The content of other elements except the shell was wild than that of the plant.
