Screening and authentication of herbal formulations based on microextraction-assisted voltammetry of microparticles

摘要: A simple solid state electrochemical methodology for screening and authentication of herbal formulations is described. The proposed method based on the recording voltammetric response, in contact with aqueous buffers, microparticulate films antioxidant compounds resulting from micro-extraction dried samples ethanol or acetone. obtained responses led us to differentiate between diverse active components upon application bivariate multivariate chemometric techniques. Resolution preparations containing two more possible when well-separated signals are recorded. In favorable cases, such characteristic signatures can be used relative quantification synthetic adulterants.
