| Description |
Picrorhiza kurroa Royle ex Benth., is widely used in the Indian systems of medicine for the treatment of various liver ailments. Since, the role of oxidative stress in the pathogenesis of liver injury has become generally recognized, in present study the free radical scavenging effect of P. kurroa was assessed by on-line HPLC-DPPH and colorimetric DPPH methods. The comparative study on antioxidant activity of P. kurroa extracts by both methods revealed that colorimetric method showed very less free radical scavenging effect while HPLC-DPPH method showed high activity. Further, the kutkoside, an important ingredient of a potent hepatoprotective formulation "kutkin/picroliv" was investigated for its chemical composition by ultra-performance liquid chromatography coupled with diode array detection/electrospray ionization quadrupole time-of-flight mass spectrometry (UPLC-DAD/ESI-QTOF-MS). Kutkoside was considered to be a single compound and reported as picroside-II or kutkoside, however, present investigation illustrated that kutkoside is a mixture of iridoid glycosides namely, picroside 11, picroside IV and 6-ferulloylcatalpol.
