Offline derivatization LC-MS/MS method for simultaneous estimation of vanillin and vanillic acid in guinea pig plasma.

Aim: Vanillin used as a positive control substrate of aldehyde oxidase activity gets metabolized to vanillic acid. Low MW and low sensitivity in negative ion mode are challenges with these analytes. Our objective was to develop a simple offline derivatization LC-MS/MS method to address these challenges.

Anticlastogenic activity of morin against whole body gamma irradiation in Swiss albino mice.

Anticlastogenic activity of morin was explored against whole body gamma radiation, at a dose rate of 1.66 Gy/min in Swiss albino mice pretreated intraperitoneal or orally. Pretreatment with morin 10, 25, 50, 75, 100, 125, and 150 mg/kg, i.

Antiallergic, antipyretic, hypoglycemic and hepatoprotective effects of aqueous extract of Coronopus didymus Linn.

The aqueous extract of whole plant of Coronopus didymus LINN (CD) [Family: Bracicacea] was screened for antiallergic, antipyretic and hepatoprotective effects in rats and hypoglycemic activity in mice. The extract showed significant antiallergic, antipyretic, hypoglycemic and hepatoprotective activity at 200 and 400 mg/kg doses on oral administration. Mechanistically, CD acts as an antioxidant as evidenced by its ability to scavenge DPPH and superoxide radicals.
