Abstract

The purpose of this study was to validate the TLC-densitometry method for the determination of colchicine in the preparation of dried herbs Gloriosa superba L. include selectivity, linearity, limit of detection, limit of quantitation, accuracy and precision. In addition, make the determination of levels of colchicine in Gloriosa superba dried herbal preparations L. Selectivity trials using a mobile phase of chloroform: diethylamine (9:1) and the wavelength selected for analysis was 356 nm colchicine. Linearity test result in the regression equation y = 24308 x + 795.9 with a correlation coefficient (r) = 0.9989 and VXO = 3.999%. Test the limits of detection and quantitation limits produce regression equation y = 42722.4912x + 47.1530 with a correlation coefficient (r) = 0.9988. Obtained from the calculation of the price of 2.7 ng detection limit and quantitation limit of 8.9 ng. Accuracy test is done using standard addition, yield 88.37% recovery% - 119.3%, with an average of 100.8%. Precision test methods of generating price correlation coefficient (KV) of 10.22%. Determination of colchicine in 2,5032 g of dried herbal preparations Gloriosa superba L. obtained an average grade of 27,07 μg colchicine, to meet the therapeutic dose of 0.5 mg colchicine needed 46,1845 g of dried herbal preparations Gloriosa superba L.
