Determination of Phyllanthin and Gallic Acid In Herbal Hepatoprotective Formulation By TLC-Densitometry Analysis
Introduction: Phyllanthus niruri, Andrographis paniculata and Embilica officinalis are most important and high value medicinal plant known for its hepatoprotective activity. Several analytical methods including HPtlc and HPlc are reported for respective phytoconstituents. However, there is no simultaneous estimation of phyllanthin and gallic acid reported. the Objective of present work is to de...
متن کاملStability-indicating Methods for the Determination of Sertaconazole Nitrate by Micelle-enhanced Spectrofluorimetry and Tlc-densitometry
Two sensitive and selective stability-indicating methods were developed for the determination of sertaconazole nitrate (Ser-NO3), in the presence of its acid, alkaline and oxidative degradation products. The first method was based on measuring the fluorescence intensity of the drug at λex/λem = 231 nm/312 nm. The influence of micelle medium on the fluorescence emission was studied. The nonionic...
متن کاملQualitative and quantitative determination of protopine in Fumaria spp. by TLC-densitometry method
Article info: Received: 25 October 2012 Accepted: 21 December 2012 ABSTRACT A rapid and accurate TLC-densitometry method for qualitative and quantitative determination of protopine has been developed. The best separation was achieved using a mobile phase chloroform – ethyl acetate – methanol – ammonium hydroxide (80:80:40:0.05, v/v/v/v). The results obtained by this method (CV% 3.4) corresponde...
متن کاملQuantification of Sunscreen Ethylhexyl Triazone in Topical Skin-Care Products by Normal-Phase TLC/Densitometry
Ethylhexyl triazone (ET) was separated from other sunscreens such as avobenzone, octocrylene, octyl methoxycinnamate, and diethylamino hydroxybenzoyl hexyl benzoate and from parabens by normal-phase HPTLC on silica gel 60 as stationary phase. Two mobile phases were particularly effective: (A) cyclohexane-diethyl ether 1 : 1 (v/v) and (B) cyclohexane-diethyl ether-acetone 15 : 1 : 2 (v/v/v) sinc...
متن کاملAnalysis of Nefopam by TLC-densitometry. A Study of Degradation Mechanism in Solutions Under Stress Conditions.
A new, simple, selective, precise and accurate thin-layer chromatographic method for quantification of nefopam hydrochloride in formulations has been established and validated. TLC F254 silica gel plates in combination with a mixture of chloroform : methanol : glacial acetic acid (9 : 2: 0.1, v/v/v) as mobile phase were used. UV detection was performed densitometrically at a wavelength of 222nm...
