摘要: 建立玛咖酰胺测定方法,测定不同产地玛咖切片中玛咖酰胺含量。采用HPLC法,色谱条件为Sepax Sapphire C18色谱柱(250 mm×4.6 mm,5 μm)流动相:乙腈(A)-0.05%磷酸水溶液(B),梯度洗脱:0~15 min,90%~95%A;15~50 min,95%A。检测波长208 nm,体积流量1.0 mL/min,柱温30 ℃。酰胺1、酰胺2、酰胺3分别在0.88~132 μg/mL、0.85~128 μg/mL、0.96~144 μg/mL线性关系良好。酰胺1、酰胺2平均回收率分别为99.21%(RSD=1.64%)、98.59%(RSD=1.75%)。不同产地玛咖中玛咖酰胺含量差别较大,建立可靠、准确、重复性好的检测方法,有利于评价不同产地玛咖的质量。

Abstract: The objective of this study was to establish a method for analyzing the contents of macamides in Lepidium meyenii by HPLC. The chromatographic conditions were as follows: A Sepax Sapphire C18 (250 mm × 4.6 mm,5 μm) column was used with the mobile phase consisting of acetonitrile (A) and 0.05% phosphoric acid (B),from 90% to 95% (A) in 15 min and maintained at 95% (A) in 15-50 min; detection wavelength was 208 nm; flow rate: 1.0 mL/min; column oven temperature was 30 ℃. The linear ranges of macamide 1,macamide 2 and macamide 3 were 0.88-132 μg/mL,0.85-128 μg/mL and 0.96-144 μg/mL,respectively. The average recoveries of macamide 1 and macamide 2 were 99.21% (RSD=1.64%) and 98.59% (RSD=1.75%),respectively. The results showed that there were great differences in the contents of macamides in L. meyenii from different regions. The developed HPLC method was reliable,accurate and reproducible for the quality evaluation of Maca from different origins.
