Abstract
A simple, accurate and precise HPTLC method has been developed for the estimation of rutin from the aerial parts of Alhagi pseudalhagi (M. Bieb) Desv. The method employed silica gel 60 F254 precoated plates as stationary phase and a mixture of ethyl acetate: acetic acid: formic acid: water (10:1:1:1 v/v/v/v) as mobile phase. Densitometric scanning was performed at 366 nm after derivatizing the resolved peaks with anisaldehyde-sulphuric acid reagent. Beer’s law was obeyed in the concentration range of 400-1200ng/spot with regression equation for standard rutin as Y= 7.658x - 53.86 and r2=0.9885. The Retention factor for rutin is 0.39 ± 0.008. The % RSD (n=9) for interday, intraday precision and the recovery values were found to be 1.31% and 1.46% and 99.55-101.12%, respectively. The method was validated as per ICH Guidelines, proving its utility in estimation of rutin from the aerial parts of Alhagi pseudalhagi (M. Bieb) Desv.
