چکیده :

Saffron, with the scientific name Crocus sativus L, is a monocotyledonous and perennial plant, herb without aerial stem and corms, belonging to the Iridaceae family. which has always been interesting for its medicinal and medicinal properties. Dry stigma (saffron) is usually used as food coloring, flavoring and medicine. The qualitative value of saffron is due to the presence of the main secondary metabolites and their derivatives, which include several beta-carotenes, including the yellow compounds crocin (crocin) responsible for the color of saffron, bitter substances picrocrocin (picrocrocin) responsible for the bitter taste of saffron and saffranal (saffranal) responsible for the aroma. And its smell is not only effective in reducing blood sugar, but also has anti-inflammatory and antioxidant properties. Considering that the medicinal properties of plants are created by their secondary metabolites, and the importance of the production of plant secondary metabolites, the present study, with the aim of investigating the secondary metabolites of saffron and the effect of plant age on the amount of production of these metabolites in completely organic conditions and The same was done in the medicinal plant nursery of Zanjan University, in order to determine the best biological age for the production of secondary metabolites for the saffron plant. In this research, techniques and methods such as spectrophotometry and chromatography, such as gas chromatography coupled to mass spectrometry (GC MS), were used to measure the amount of secondary metabolites and determine their structure.. Examining the results of the analysis of three compounds, crocin, picrocrocin, and safranal in three fields with different ages of one year, two years, and five years shows that the lowest amount of crocin is for the first year and the highest is for the fifth year, the lowest amount of picrocrocin is for the year The fifth and the highest is related to the first year, in the case of safranal, the amount of safranal increases with age, that is, the lowest amount for the first year and the highest amount of safranal is related to the fifth year. The results of this research show that we can use the different biological growth ages of this plant to obtain each of these main metabolites. These results are reported for the first time in saffron
