摘要: 利用固相微萃取技术提取唐古拉特白刺和西伯利亚白刺叶的挥发性成分,采用气相色谱-质谱联用结合保留指数法鉴定了其成分。分别从唐古拉特白刺叶和西伯利亚白刺叶中的挥发油中鉴定出40、33个化合物,二者共有成分27个。对比二者的挥发性成分,发现唐古拉特白刺叶烃类化合物(25.54%),远高于西伯利亚白刺叶(12.00%),并且以二十一烷为转折点,在此之前,各烃类化合物的在唐古拉特白刺叶中的含量均高于西伯利亚白刺叶,在此之后,烃类化合物在前者中的含量低于后者;乙酸仅存在于西伯利亚白刺叶中,且含量高达20.00%,二氢猕猴桃内酯为二者叶中的主要赋香成分。

Abstract: The chemical constituents of the volatile oil from the leaves of Nitraria tangutorum and N. sibirica were extracted by solid-phase microextraction technique, and identified by GC-MS combined with Kvotas retention index. Forty and thirty-three compounds were identified from the leaves of N. tangutorum and N. sibirica respectively, and twenty-seven were mutual. The content of hydrocarbons in N. tangutorum (25.54%) was higher than that of N. sibirica (12.00%). As the turning point, the content of hydrocarbons compounds which retention times were earlier than heneicosane in N. tangutorum was higher than that of N. sibirica. And acetic acid (20.00%) was only detected in N. sibirica. The main fragrance components in N. tangutorum and N. sibirica was 5,6,7,7a-tetrahydro-4,4,7a-trimethyl-2(4H)-benzofuranone.

Key words: Nitraria tangutorum; N. sibirica, volatile oil
