A stability-indicating high-performance thin-layer chromatographic (HPTLC) method for determination of tenofovir disoproxil fumarate in bulk drug and in tablet has been developed and validated. The mobile phase selected was chloroform:methanol (9.0:1.0, v/v) with ultraviolet (UV) detection at 260 nm. The retention factor was found to be 0.49 ± 0.03 with correlation coefficients of 0.9994 in the...

Stevioside, a major sweet component of leaves of Stevia rebaudiana (Bertoni), is about 300 times sweeter than sucrose. Highly refined stevia leaf extracts and stevioside are officially used as low calorie sweeteners in many countries. The present study describes a method for rapid identification and estimation of stevioside in commercial samples using HPTLC and HPLC. Identification of steviosid...

Nowadays, plants have been considered as powerful agents for treatment of disorders regarding to their traditional use. In Iranian Traditional Medicine (ITM), plants have a special role in the treatment of various diseases. Burns with their devastating outcomes have been discussed in ITM as well. In the present study, a polyherbal ointment (PHO), retrieved from ITM, was formulated for burn heal...

A simple, accurate and rapid high performance thin layer chromatography (HPTLC)-densitometric method was developed for separation and determination of cetirizine (CET) as a long acting antihistamine and montelukast (MON) as an antileukotriene in pharmaceutical dosage forms. The compounds were separated on silica gel 60 F254 HPTLC plates using a mixture of ethyl acetate : methanol : ammonia solu...
