A highly sensitive method for detection and quantification of swertiamarin, mangiferin and amarogentin in Swertiachirata
(Gentianaceae).The leaves, roots, stem, flowers and tissue cultured plants were extracted with 80% methanol in a bath
sonication for rapid extraction of metabolites. The desired separation and baseline was obtained in a gradient method where
mobile phase A was composed of 0.1% TFA in water and mobile phase B was a mixture of acetonitrile: water in the ratio of 70:30.
The linear gradient at a flow rate of 1.0ml/min was start with 15% B; 20% B in next 5 min, 70% B in next 25 min, hold for 5 min;
15%B in next 5 and equilibrated for 5 min at 240 nm UV wavelength. The separation was obtained on Waters Spherisorb 5μm
ODS2 (250 mm x 4.6 mm). The LOD of swertiamarin, mangiferin and amarogentin were found to be 0.4μg/ml, 0.2μg/ml and
0.3μg/ml respectively. The LOQ of swertiamarin, mangiferin and amarogentinwere found to be 1.0μg/ml, 0.4μg/ml and 0.9μg/
ml respectively. The method can be used as quality control of plant material and also identification of
due to the presence of marker compound amarogentin.
