**4. Conclusions**

Especially recently, many of the beneficial properties of fenugreek have been experimentally proven and the potential of fenugreek's therapeutic applications has been demonstrated. It has high economic values because of including a lot of bioactive compounds. The important compounds can be listed steroidal sapogenins such as diosgenin, alkaloids as trigonelline, flavonoids, tannins, amino acids, steroidal glycosides, protein and others.

As can be seen from this review, the phenolic acids, dietary fiber, saponins and proteins contained in fenugreek are valuable additives to improve human nutrition. Additionally, in neurological studies conducted with fenugreek, the antidiabetic, antifertility, anticancer, antimicrobial, antiparasitic, lactation stimulating and hypocholesterolemic effects of fenugreek have been proven by many researchers. So, it has been also universally used as a spice in a conventional food or it has been interfered to prepare for some functional foods.

In the future, studies on fenugreek are needed some important applications to increasing the popularity of fenugreek. In this context, researchers should be focused quality criteria as primer or secondary metabolite, different cultural and molecular application, different techniques from sown to harvest times of fenugreek. Further research will be required to determine to know the molecules responsible the antioxidant properties in these extracts. Also, fenugreek germplasm can be collected and subjected to intensive selection via modern breeding programs. In addition to these, by selecting genotypes with superior characteristics, gene transfer can be made by determining suitable genes among these genotypes and new fenugreek genotypes with desired properties can be obtained. In addition, studies on fenugreek leaves are limited and generally focused on fenugreek seeds. In this context, researchers should be focused the quality criteria as primer or secondary metabolite in fenugreek leaves.

This study will help the researchers to obtained optimal fenugreek production, optimum biochemical components and adapt to difference environmental, other and specific farming conditions. In the future, when fenugreek is evaluated with all these aspects, its economic, industrial and medicinal value may increase and add value to the relevant sector.
