CHAVEZ PEREZ, Jorge et al. Determination and Quantification of Plumbagina by HPLC-UV Extracted from Dionaea muscipula E. Cultivated in vitro. Rev. Soc. Quím. Perú [online]. 2017, vol.83, n.4, pp.382-390. ISSN 1810-634X.

Background: Dionaea muscipula called "venus flytrap" is the only species of the genus Dionaea belonging to the group of "carnivorous plants" that besides its ornamental appeal nowadays is studied for the isolation of secondary metabolites, having finding various compounds with direct activity in different diseases. Plumbagin (2-methyl-5-hydroxy-1,4-naphthoquinone), has been reported in different genres such as Plumbago species (Plumbaginaceae), Drosera and Dionaea (Droseraceae) and Diospyros (Ebenaceae) describing activities like antispasmodic, antibacterial, antiparasitic antifungal, anti-rheumatic pain and anti-cancer. The aim of this study is to develop a method by HPLC UV reliable for the determination of plumbagina. The method presented a linearity r2 = 0.997569 for concentrations between 10 and 50 ug / ml, with limits of detection (LOD) and quantitation (LOQ) of 0.09 g / ml and 0.3 ug/ ml respectively. The accuracy of the results was expressed as a% RSD of 1.34 to 5.76 intra diary and inter diary for analysis. The accuracy in maximum recovery of 94.71% plumbagina was obtained. It is concluded that the proposed method is simple, accurate and precise and can be tested for the rapid determination of plumbagina
