摘要:
为了建立同时测定玛咖中亚麻酰胺、亚油酰胺、十六烷酰胺、甲氧亚麻酰胺、甲氧亚油酰胺、甲氧十六烷酰胺、油酰胺和十八烷酰胺含量的HPLC-PAD方法,样品用正己烷超声波辅助提取,采用Waters Symmetry Shield色谱柱(C18, 5 μm, 4.6 mm×250.0 mm),以乙腈-水溶液为流动相进行梯度洗脱,检测波长为200 nm,外标法定量。结果显示,8种酰胺类化合物在 0.05~10.00 mg/L具有良好的线性,相关系数≥0999,检出限为 0.08~022 mg/kg,定量限为 0.26~0.76 mg/kg。20 mg/kg、50 mg/kg和100 mg/kg添加水平的加标样回收率为 77.0%~117.0%,相对标准偏差为 1.58%~5.12%。表明该方法操作简单,重复性和稳定性好,适合玛咖中8种酰胺类化合物同时检测和定量分析。
Abstract:
To establish a HPLC-PAD method to determine eight macamide components, N-benzyl-(9Z, 12Z, 15Z)-octadecadienamide, N -benzyl-(9Z, 12Z, 15Z)-octadecatrienamide, N-benzyl-(9Z, 12Z)-octadecadienamide, N-benzyl-(9Z, 12Z)-octadecadienamide,N-(3-methoxybenzyl)-hexadecanamide,N-(3-methoxybenzyl)-benzyloctadecanamide, N-benzyl-(9Z)-octadecenamide, and N-benzyloctadecanamide in Lepidium meyenii Walp.〖KG-*3〗, the sample was extracted by hexane with ultrasound assistance. The chromatographic separation was performed on Waters Symmetry Shield column(C18, 5 μm, 4.6 mm×250.0 mm) by using water solution-acetonitrile as the mobile phase. The photodiode array detector (PAD) wavelength was set at 200 nm. The calibration curve was liner in the range of 0.05-10.0 mg/L with the correlation coefficients more than 0.999. The limit of detection was from 0.08 to 0.22 mg/kg and the limit of quantification was from 0.26 to 0.76 mg/kg for eight macamide components. The spiked recoveries of 20 mg/kg, 50 mg/kg and 100 mg/kg ranged from 77.0% to 117.0%, with the relative standard deviations (RSDs) being 1.58%-5.12%. The method showed good repeatability, accuracy and stability, and could be applied in the accurate quantification of eight macamide components in Lepidium meyenii Walp.
