Method development and validation for simultaneous estimation of methotrexate and curcumin in Bulk Drug by using RP-HPLC

Abstract

Curcumin is the natural herb that shows effect in the treatment of cancer and rheumatoid arthritis and methotrexate is well known anticancer and anti-rheumatoid drug. Literature survey reveals that there was no method available for the selected drug combination. So, here an attempt has been made to develop simple, rapid and economic method for simultaneous estimation of methotrexate and curcumin in bulk drug by using RP-HPLC method. The percentage assay from optimized method was found to be 99.68% and 99.76% for methotrexate and curcumin respectively. The proposed method was validated for linearity, accuracy, precision and robustness according to ICH guidelines and were found to be within the standard range.
