developed for the estimation of phyllanthin (1) and hypophyllanthin (2), the important lignans
of Phyllanthus species, especially Phyllanthus amarus. Separation of 1 and 2 was carried

the analytes were visualised through colour development with vanillin in concentrated
sulphuric acid and ethanol. Scanning and quantification of spots was performed at 580 nm …
