Item type:Publicación, Identification and quantification of components in extracts of Uncaria tomentosa by HPLC-ES/MS.(2004); ;Carbone, V ;Quiroz, J de Dioz Zuniga ;De Simone, FPizza, CThe two main classes of secondary metabolites, alkaloids and quinovic acid glycosides, of Uncaria tomentosa (Willd.) DC. (Rubiaceae), a Peruvian plant commonly known as 'uña de gato', have been analysed. Separation of the alkaloidal fraction was achieved using a solid phase extraction method based on cationic exchange, and an analytical method employing HPLC-ES/MS has been developed. Quantitative data for commercial wild bark, cultivated bark and leaves are reported. The analysis of quinovic acid glycosides was performed directly on the crude extract using both a fast analytical method based on flow injection ES/MS, and a more complete analytical technique using HPLC-MS. - Some of the metrics are blocked by yourconsent settings
