A simple reversed phase high performance liquid chromatographic (RP-HPLC) method was established for simultaneous quantification of luteolin and quercitin in the two medicinally important plants, Gmelina arborea Roxb. and Kalanchoe pinnata(Lam.) Pers. Linear response was found in the concentration range of 1.0-500 μg/mL for Gmelina arborea Roxb. and 0.5-500 μg/mL for Kalancho epinnata(Lam.) Pers. respectively. The relative standard deviation for inter-day and intra-day precision was found to be <2%. Precision,specificity and robustness studies were carried out, values less than two (% R.S.D) were observed. Recovery values from 98.53 to 98.93 indicated that the accuracy of the method was good. The proposed developed method was found to be precise, accurate and reproducible and can be used for routine quality control analysis and for the quantitation of quercitin and luteolin in herbal raw materials as well as in their formulations.
