biochemical compositions of mosir tubers (allium stipitatum regel.) under the influence of different geographical conditions of iran

Mosir (allium stipitatum) is an edible and medicinal plant native to iran. it belongs to the amaryllidaceae family and is one of the most important plant sources of sulfur compounds and antioxidants. to investigate the biochemical properties of mosir tubers collected from various western regions of the country. an experiment was designed, and mosir tubers were collected from each ecotype, which consisted of five habitats: asadabad, bahar, tuyserkan, hamedan, and kangavar. the traits of allicin, total polyphenol, protein, and percentage of dry matter were studied. the results of the analysis of variance for each of the studied traits indicated a significant difference among the various mosir collection points in terms of tuber dry matter percentage, protein percentage and total polyphenol percentage. mosir from hamedan exhibited the highest protein content, while tuyserkan had the lowest. the highest percentage of tuber dry matter was found in bahar and the lowest in asadabad. bahar and asadabad mosirs had the highest total polyphenols, while hamedan mosirs had the lowest percentage of total polyphenols. it appears that among the studied areas, bahar city provides more favorable conditions for the growth and accumulation of biochemical compounds in mosir tubers, which are valuable in the pharmaceutical industry.
