Abstract:

Objective: To determinate the content of total alkaloids in Maca from different origins with acid dye colorimetry for evaluating
thequality. Methods: Takingtheoxymatrineasreferencesubstance,UV-visiblespectrophotometrywasusedtodeterminatethecontentof
total alkaloid Maca, and extraction method, the amount of coloring agent, pH value, determine wavelength were observed as well. Results:
Ultrasonic extraction was used to extract for three times with 40 minutes each time and the amount of reagent was 6 mL, pH was 7.2, and
measurement wavelengthλ was 415 nm. Maca produced in Peru, Lijiang and Diqing enjoy higher content of total alkaloids. Conclusion:
Thismethodissimple,sensitive,andreproducible,whichcanbethemethodofdeterminingthecontentoftotalalkaloidsinMaca.

Key words: Maca, total alkaloids, UV - visible spectrophotometry, determination
