摘要: 利用索氏提取法提取罗勒籽油,向罗勒籽油加入氢氧化钾甲醇溶液后并用水浴加热,加入正己烷和蒸馏水萃取,上清液即为罗勒籽油中脂肪酸,用气相色谱质谱法(GC/MS)对脂肪酸进行鉴定。共鉴定出了4种脂肪酸,其中α-亚麻酸为62.88%、亚油酸为20.66%、棕榈酸为10.67%、硬脂酸为5.79%。对罗勒籽脂肪酸进行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为11.12 μg/mL。该研究为深入研究罗勒籽的药理作用提供了科学依据。

Abstract: Fats and oil were extracted by Soxhlet extraction from the seeds of Ocimum basilicum L.. And then fats and oil were dissolved in KOH of methonal with water-bath. Lastly, the fatty acids were extracted with n-hexane. The chemical constituents of the fatty acids were identified and quantified by means of capillary gas chromatography combined gas Chromatography-mass spectrometry. The results indicated that the fatty acids included four kinds of fatty acids: α-linolenic acid (62.88%), linoleic acid (20.66%), hexadecanoic acid (10.67%) and octadecanoic acid (5.79%). The fatty acids had strong inhibiting effect on PTP1B with IC50 value of 11.12 μg/mL. The results provided the basis for further study of the seeds of O. basilicum.

Key words: Ocimum basilicum L. seeds, fatty acid, gas chromatography-mass spectrometry, PTP1B
