- Abstract
Abstract: Traditional Chinese herbal medicine has long enjoyed the reputation of the world's most advanced system of natural medicine. <italic>Pinellia ternata</italic> is one of the most commonly used herbs in the traditional Chinese medical science. In this study, five representative ingredients of <italic>Pinellia ternata</italic> guanosine, methionine, glycine, 3,4‐dihydroxybenzaldehyde, and homogentisic acid, were assayed using simple derivatization procedures. Under optimized experimental condition, five analytes in <italic>Pinellia ternata</italic> were rapidly separated and detected using microchip electrophoresis, affording the benefits of speed, minimal sample requirements, and sensitive on‐the‐chip electrochemical detection, in 5 min with linearity over a concentration of 20–500 μM (<italic>R</italic>2 = 0.994) with nearly complete recovery (95.6–98.5%).
