Development and Validation of HPTLC Method for Simultaneous Estimation of Resveratrol and Piperine in Its Pharmaceutical Dosage Form

Abstract

Resveratrol is a plant compound that work as antioxidant and it also has anti-aging properties whereas Piperine is a alkaloid and it majorly used in spices.  A HPTLC (High performance thin layer chromatography) study is conducted for estimation of Resveratrol and Piperine. The Mobile phase used was Chloroform: Ethyl Acetate (50:50 v/v). Rf Value of Resveratrol 0.59 and Piperine 0.79 was found. Stationary phase of Silica gel 60 F254 was used. Densitometric analysis was performed at 325 nm. The method was found to be linear. Recovery (ranging from 97% to 102.24 %), limit of detection (40.26 ng/spot, 1.64 ng/spot respectively for resveratrol & piperine), limit of quantification (122.02 ng/spot, 4.98 ng/spot respectively for resveratrol & piperine) and precision (≤ 2.00%) were found to be satisfactory. Validation performed with linearity, accuracy, precision, specificity, robustness, limit of detection and limit of quantification. Every parameter found within the range. The developed method allows to confirm that an accurate and reliable potency measurement of a pharmaceutical preparation can be performed.
