Abstract

Schisandrae chinensis fructus (Wuweizi) contains many triacylglycerols (TAGs). Therefore, it is inevitable that these TAGs will be part of Chinese medical preparations of Schisandrae chinensis fructus. It is important to identify TAGs in Schisandrae chinensis fructus. Fatty acids in Schisandrae chinensis fructus oil were identified by gas chromatography−mass spectrometry (GC−MS) after transesterification. TAGs were determined by liquid chromatography−mass spectrometry (LC−MS) and confirmed by high-resolution Fourier transform-ion cyclotron resonance-mass spectrometry (FT−ICR−MS). Seven kinds of fatty acids were detected in Schisandrae chinensis fructus oil of which linoleic acid (L) and oleic acid (O) accounted for 93%. Also, 7 TAGs were recognized in the oil. LLL, OLL, OOL and PLL were the main components (P corresponds to palmitic acid). The LLL composed approximately half of the oil of Schisandrae chinensis fructus by mass. The composition of fatty acids and TAGs in Schisandrae chinensis fructus was determined by GC−MS, LC−MS and FT−ICR−MS.

五味子五味子油中脂肪酸和三酰基甘油的鉴定

摘要

五味子五味子（Schisandrae chinensis fructus）含有许多三酰基甘油（TAGs）。因此，这些标记不可避免地将成为五味子的中药制剂的一部分。鉴别五味子的TAGs具有重要意义。酯交换反应后，通过气相色谱-质谱法（GC-MS）鉴定了五味子五味子油中的脂肪酸。通过液相色谱-质谱法（LC-MS）确定TAG，并通过高分辨率傅立叶变换离子回旋加速器共振质谱（FT-ICR-MS）进行确认。检出7种脂肪酸。五味子五味子油中亚油酸（L）和油酸（O）占93％。此外，在油中还发现了7种TAG。LLL，OLL，OOL和PLL是主要成分（P对应于棕榈酸）。按质量计算，LLL约占北五味子油的一半。用GC-MS，LC-MS和FT-ICR-MS测定五味子中脂肪酸和TAG的组成。
