High-performance thin layer chromatographic quantification of bioactive psoralen and daidzein in leaves of Ficus carica L

This study was undertaken to quantify psoralen and daidzein by high-performance thin layer chromatography (HPTLC). The methanolic extract of 10 mg mL(-1) concentration solution was prepared for HPTLC quantification of psoralen and daidzein. HPTLC aluminium-backed plates coated with 0.2 mm layers of silica gel 60 F(254) were used as the stationary phase. The working standard solution of psoralen and daidzein was applied along with the test sample solution by means of Camag Linomat IV sample applicator. R (f) values of psoralen and daidzein were found to be 0.60 and 0.88, whilst as their percentage values in methanolic extract were found to be 3.02% and 5.64% (w/w), respectively. A simple quantitative estimation method of psoralen and daidzein by HPTLC is reported that can be used for the quality control of marketed preparations containing Ficus carica. However, further study is warranted to isolate and quantify active constituents present in the leaves of F. carica by sophisticated techniques.
