HPLC fingerprint and simultaneous quantitative analysis of phyllanthin and hypophyllanthin for identification and authentication of Phyllanthus niruri from related species

Abstract A precise and accurate method for the identification and authentication of Phyllanthus niruri L. from P. debilis Klein ex Willd. and P. urinaria L., Phyllanthaceae, was developed using high-performance liquid chromatography. Chromatographic fingerprint analysis was combined with simultaneous quantification of phyllanthin and hypophyllanthin for the developed method. Phyllanthin and hypophyllanthin were successfully separated and quantified under this proposed method. The highest amount of phyllanthin and hypophyllanthin was found in P. niruri compared to P. debilis and P. urinaria. Fingerprint chromatogram of the three Phyllanthus species showed distinct profiles that these may be used to identify and authenticate each Phyllanthus species, which improved by marker compounds present in each species. The combination of chromatographic fingerprint analysis and discriminant analysis was successfully discriminated all three species, including P. niruri adulterated with P. debilis or P. urinaria. The method can be used for the identification and authentication of P. niruri from related species, such as P. debilis and P. urinaria.

Quantitative determination of phyllanthin in Phyllanthus amarus by high-performance thin layer chromatography

A simple, precise and rapid high-performance thin-layer chromatographic method has been developed for the estimation of phyllanthin and is the important lignans of Phyllanthus amarus. Separation of phyllanthin was carried out on silica gel 60 F254 layers eluted with hexane: ethyl acetate (2:1), and the analytes were visualized through colour development with 10 percent concentrated sulphuric acid in ethanol. Scanning and quantification of spots was performed at 200 nm. The proposed method being precise and sensitive can be used for the detection, monitoring and quantification of phyllanthin from Phyllanthus amarus.

Un método simple, preciso y rápido de cromatografía de capa fina de alto rendimiento ha sido desarrollado para la estimación de phyllantina y los lignanos importante de Phyllanthus amarus. La separación de phyllantina se llevó a cabo en capas de silica gel 60 F254 eluidas con hexano: acetato de etilo (2:1), y los analitos fueron visualizados mediante el desarrollo de color con un 10 por ciento de ácido sulfúrico concentrado en etanol. Los análisis y cuantificación de los puntos se realizó a 200 nm. El método fue validado.
