Abstract

Stigmas of Crocus sativus L. (Iridaceae), also known as saffron, is a very famous spice in the world and has many biological effects. Crocin I, picrocrocin and safranal are the main compounds that determine the quality and value of saffron. The aim of the research developed the method to determine the amount of crocin I, picrocrocin, and safranal in saffron using high performance liquid chromatography (HPLC) with PDA detector. The results showed extraction conditions, also HPLC coditions to quantify three markers. The method was validated about the specificity, prescision, accuracy, linear range of picrocrocin, crocin I, safranal respectively was 125 - 350 µg/ml; 250 - 600 µg/ml; 0,5 - 2,0 µg/ml.
