摘要：建立云南栽培玛咖的总生物碱含量的分析方法,分析评价3种色型玛咖的总生物碱含量。分别采用酸性染料比色法和酸碱滴定法对云南栽培的3种色型玛咖的总生物碱含量进行测定。结果表明:酸性染料比色法灵敏度高,相对标准偏差较小,是玛咖总生物碱含量测定的适宜方法;紫色、白色和黄色3种色型玛咖的总生物碱含量分别为4.4078、2.9193、2.2241mg/g,差异达到极显著水平(P<0.01);其中紫色玛咖的总生物碱含量最高,并与相关文献测定的来源于秘鲁的玛咖干粉的总生物碱含量相近。
In this syudy, a determination method was established to analyze the contents of total alkaloids in Maca （Lepidium meyenii） cultivated in Yunnan with 3 kinds of different color. Total alkaloids in 3 color types of Maca were analyzed by acidic dye colorimetry and titration, respectively. Results indicated that acidic dye colorimetry was sensitive with less relative standard deviation （RSD）. This method is more appropriate for the determination of total alkaloids in Maca cultivated in Yunnan; The contents of total alkaloids in purple Maca, white Maca and yellow Maca cultivated in Yunnan were 4.4078, 2.9193 and 2.2241 mg/g, respectively, with a significant difference （P 0.01）. The content of total alkaloids in purple Maca is the highest, which is close to the content of total alkaloids in Maca grown in Peru.
