ABSTRACT
Abstract This paper describes the quantification of catechin in the spray-dried extract of Pimenta pseudocaryophyllus (Gomes) Landrum, Myrtaceae, citral chemotype using a validated HPLC-PDA method. The method employs a RP-18 column with acetonitrile:water-orthophosphoric acid 0.05% (gradient system) and UV detection at 210 nm. The method was demonstrated to be simple, sensitive, specific, linear, precise, accurate and robust. The response was linear over a range of 5-200 µg/ml (r > 0.999). The range of recoveries was 92.27-102.54%. The relative standard deviation values for intra- and inter-day precision studies were 4.30 and 3.78%, respectively. This assay can be readily utilized as quality control method for catechin in the dried extract of P. pseudocaryophyllus.
