DETERMINATION OF SIBUTRAMINE ADULTERATED IN HERBAL SLIMMING PRODUCTS USING TLC DENSITOMETRIC METHOD

A Validated TLC-Densitometric Method for the Determination of Mesterolone in Bulk Material and in Tablets

Mesterolone is a synthetic androgenic steroid indicating a weak anabolic activity. A new, simple in use, and economical TLC-densitometric method in normal phase system (NP-TLC) has been developed and validated for the identification and quantitative determination of mesterolone in bulk drug and in tablet formulation. NP-TLC analysis was performed on aluminium plates precoated with silica gel 60...

Validated TLC-densitometric method for determination of oxyresveratrol contents in ma-haad (Artocarpus lakoocha) heartwood extracts

Atrocapus lakoocha Roxb. or Ma-haad, is a tree in Moraceae family. The main stilbenoid in the heartwood of this plant, oxyresveratrol is an active substance that promotes strong tyrosinase inhibitory and antioxidative effects. In this study, thin layer chromatographic (TLC) – densitometric method was developed and validated to quantitative analyze of oxyresveratrol contents in aqueous and ethan...

A validated stability-indicating TLC-densitometric method for the determination of stanozolol in pharmaceutical formulations

BACKGROUND Stanozolol is a synthetic derivative of dihydrotestosterone (DHT), and one of the frequently detected anabolic steroids in doping analysis. The current work describes the development and validation of the stability-indicating TLC-densitometric method for sensitive and specific estimation of stanozolol even its degradation product being there. Precoated silica gel TLC aluminium plates...

VALIDAtIoN oF tLc – DeNsItoMetRIc MetHoD FoR IDeNtIFIcAtIoN AND DeteRMINAtIoN oF estRADIoL

The aim of current study was the validation of TLC densitometric method for identification and determination of Estradiol hemihydrate in dosage forms. The TLC conditions were: glass plates with Silicagel G60F254; mobile phase: chloroform : water = 90 : 10 v/v. Linearity accordance between the concentration and spot area in range: 5.10-4 g/ml ÷ 5.10-3 g/ml is proved by the regression equation: y...
