font size="1" face="GulliverRM"> The quantitative determination of boldine alkaloid in boldo leaf extracts by employing cyclic voltammetry,at a liquid/liquid interface as well as the validation of this methodology against the referencemethod, high performance liquid chromatography (HPLC), are reported in the present paper. The voltammetric analysis was performed successfully and economically using two kinds of liquid/liquid interfaces: water/1,2-dicholoroethane and water/PVC (polyvinyl chloride)–gelled 1,2-dichloroethane. Linear calibration curves in the concentration range of 1.04×10−5
