摘要: 利用三种不同溶剂(正己烷、乙醚、氯仿)经索氏提取法提取阿纳其根中的油脂成分,经甲酯化后,用气相色谱质谱法(GC-MS)对脂肪酸组成进行了分析和鉴定。试验结果显示,正己烷提取油脂中共鉴定出了8种脂肪酸,其中亚油酸为36.341%、棕榈酸为34.268%、油酸为19.656%;乙醚提取油脂中共鉴定出了12种脂肪酸。其中亚油酸为34.102%、棕榈酸为32.916%、油酸为20.000%、亚麻酸为5.329%;氯仿提取油脂中共鉴定出了5种脂肪酸。其中亚油酸为42.427%、棕榈酸为40.952%、油酸为11.250%。对阿纳其根脂肪酸进行蛋白酪氨酸磷酸酯酶1B(PTP1B)的抑制作用研究,结果表明脂肪酸对PTP1B有较强的抑制作用,其IC50分别为5.27±0.40、4.71±0.08、7.01±1.98 μg/mL。该研究为深入研究阿纳其根的药理作用提供了科学依据。

Abstract: Fats and oil components were extracted by Soxhlet extraction from Anacyclus pyrethrum (L) DC using three different organic solvent (n-hexane,diethyl ether,chloroform).The chemical constituents of fatty acids in different extracts were identified and semi-quantified by gas chromatography-mass spectrometry (GC-MS).The results indicated that 8 components,mainly including linoleic acid (36.341%),hexadecanoic acid (34.268%) and oleic acid (19.656%),were detected in the n-hexane extract;12 components,mainly including linoleic acid (34.102%),hexadecanoic acid (32.916%),oleic acid (20.000%) and α-linolenic acid (5.329%),were detected in the diethyl ether extract;5 components,mainly including linoleic acid (42.427%),hexadecanoic acid (40.952%) and oleic acid (11.250%),were detected in chloroform extract.In addition,the fatty acid extracts showed strong inhibiting effect on PTP1B,and their IC50 values were 5.27±0.40,4.71±0.08,7.01±1.98 μg/mL respectively.The results provided the basis for further study of Anacyclus pyrethrum (L) DC.
