FINGER PRINTING ANALYSIS OF THE PHENOLS FROM HOLOPTELEA INTEGRIFOLIA (ROXB.) PLANT LEAVES USING HPTLC

摘要

The present study was conducted to identify the phenols from methanol extracts (MHI) of medicinally and economically useful leaves of Holoptelea integrifolia (Roxb.) plant using High Performance Thin Layer Chromatography (HPLC) technique. Preliminary phytochemical screening was done and HPTLC studies were carried out on CAMAG HPTLC system equipped with Linomat V applicator (Switzerland). Densitometric scanning was performed with Camag TLC scanner IV in the reflectance absorbance mode at 540 nm and operated by Win CATS software (1.4.6 Camag) with the help of tungsten lamp. Preliminary phytochemical screening of methanolic extract of Holoptelea integrifolia showed the presence of steroids, alkaloids, flavonoids, proteins, phenols and carbohydrates. HPTLC finger printing of phenols of methanolic extract of leaf revealed seven polyvalent phytoconstituents (7 peaks) and corresponding ascending order of R_f values in the range of 0.15 to 0.75. From the results of preliminary phytochemical analysis and above R_f values, we have concluded the presence of phenols in methanol extracts.
