Phyllanthus species are extensively used in traditional medicines for the treatment of hepatic diseases due to their bioactive hypophyllanthin and phyllanthin. This work describes the development and validation of an ultra high performance liquid chromatography with tandem mass spectrometry method in polarity switching multiple reaction monitoring mode for the simultaneous detection and quantitation of 23 compounds using ultra-performance liquid chromatography coupled with electrosprayhybrid triple quadrupole-linear ion trap mass spectrometer. The validated parameters showed good linearity (R-2 >= 0.996), limit of detection (0.05-1.62 ng/mL), limit of quantitation (0.15-4.95 ng/mL), precisions (intra-day: RSD <= 2.11%), (interday: RSD <= 2.91%), stability (RSD <= 2.56%) and overall recovery (98.22-104.48%; RSD <= 2.93%). The validated method was successfully applied in ethanolic extracts of P. amarus, P. niruri, P. emblica, P. fraternus, fractions of P. amarus and their herbal formulations for quantitation. The maximum content of hypophyllanthin (29.40 mg/g) and phyllanthin (56.60 mg/g) was detected in ethyl acetate fraction of P. amarus. The total content of 23 compounds was abundant in the ethanolic extract of P. emblica fruit. Principal component analysis was used to differentiate the selected Phyllanthus species and their herbal formulations. The results indicated that the present method could be used for quality control of Phyllanthus species and its herbal formulations.
