Standardization and Quality Control Analysis of Marichadi tailam: An Ayurvedic Formulation

The Ayurvedic medicines are having great therapeutic application due to their natural holistic way of treatment of the disease. To ensure the effectiveness of the medicine standardization of the drug essential. Ayurvedic tailam is an important group of formulations used for treatment of various types of diseases. The principle of using tailam is better absorption of active ingredients by skin when applied through a lipophilic vehicle like vegetable oils. Marichadi Tailam is a herbal oil used for treatment of skin diseases such as eczema and dermatitis. In the present study, an attempt was made to develop and validate a HPTLC method for quantitative determination piperine in the Marichadi coconut oil and its standardization. The HTPLC separation was performed on precoated silica gel 60 F254 aluminum plate (10 × 10cm, 250μm thickness) using toluene:ethyl acetate:diethyl amine (7:2:1) as a mobile phase. The detection and quantification was performed at 340nm. The formulation contains 2.35% of piperine. Linearity studies indicated piperine in the linear ranges, while recovery studies revealed 99.32% (w/w) of piperine. The developed HPTLC method resolved and quantified piperine effectively, so it could be used as a simple reliable method for QC of polyherbal formulations.
