Spectrofluorimetric Estimation of Scopoletin in Evolvulus alsinoides Linn. and Convulvulus pluricaulis Choisy.
A simple sensitive spectrofluorimetric method was developed for the analysis of total coumarins calculated as scopoletin in the plants Evolvulus alsinoides and Convulvulus pluricaulis. The fluorescent nature of scopoletin proved to be of immense value in the development of the spectrofluorimetric method. The excitation and emission wavelengths for scopoletin were 430 nm and 460 nm respectively ...
متن کاملSpectrofluorimetric estimation of puerarin in Pueraria tuberosa.
Pueraria tuberosa (Roxb. ex. Willd.) DC. (Fabaceae) is the important plant used in Indian medicine, commonly known as Vidarikand. The plant is described as rasayana and tonic in Ayurvedic Pharmacopoeia of India (1). It is an extensive perennial climber, growing throughout tropical parts of India, mostly in moist regions, monsoon-forests and coastal tracts (2). The tuber of pueraria is sweet in ...
متن کاملDevelopment of Validated Spectrofluorimetric Method for the Estimation of Fenoverine
For the estimation of fenoverine in pure and pharmaceutical preparation a sensitive spectrofluorimetric method was developed. This wass based on the oxidation of fenoverine with cerric ammonium sulphate to produce cerrous ion, whose fluorescence was observed at 376 nm while excited at 261 nm. The calibration graph was linear over the range of 1-10 μg/ml. This is applied successfully for the ass...
متن کاملIn vitro antioxidant properties of Scopoletin
Scopoletin is a coumarin and a major component of Aegle Marmelos. In the present study, we determined the antioxidant activity of Scopoletin by employing various in vitro antioxidant assay such as 1, 1-diphenyl-2-picrul-hydrazil free radical (DPPH) scavenging, Hydrogen peroxide scavenging, superoxide radical scavenging, Hydroxyl radical scavenging activity and ferrous ion chelating activity by ...
متن کاملDevelopment and Validation of a Spectrofluorimetric Method for the Estimation of Rivastigmine in Formulations
A rapid, sensitive, simple, and cost-effective spectrofluorimetric method was developed for the estimation of rivastigmine in bulk and pharmaceutical formulations. The relative fluorescence intensity of rivastigmine was measured in triple distilled water at an excitation wavelength of 220 nm and an emission wavelength of 289 nm. Linearity range was found to be 100 to 4000 ng/ml. The method was ...
