Abstract EN

The aim of this research is to compare the content of each (Crocus sativus L.) and Crocus aleppicus B.

(a spontaneous species in Syria) of three main chemical compounds (Crocin, Picrocrocin and saffarnal) using UV-Vis spectrophotometry.

In addition to comparing them in terms of the content of Crocin and Saffranal using high-performance liquid chromatography (HPLC) method.

The results showed that C.

sativus L.

outperformed C.

aleppicus B.

when using spectrophotometer, that the absorbance of 1% aqueous solution values for Crocin, Picrocrocin and saffarnal compounds were (199.14, 77.20 and 33.55) respectively in C.

sativus L.

and (96.77, 55.05 and 17.20) in C.

aleppicus B.

While high-performance liquid chromatography technique showed that the concentration of crocin in the stigmas of C.

sativus L.

was (49.38±0.89mg.g-1 ), but, as a sequent of the high concentration of crocin in the C.

sativus samples, we extend the metanolic solutions up to 90 %, which made the Saffrnal's concentration very low and insensitive.

Whereas, the HPLC equipment detection sensitivity has been unable to identify and calculate crocin and saffranal concentrations of C.

aleppicus, but analysis showed high peaks at different times, which indicates that there may be various other chemicals in this wild species may have medical or cosmetic significance.
