Plant polyphenolic compounds have long been of interest to researchers due to their antioxidant and possibly anti-cancer effects. In this research, in order to study the phytochemical diversity of 32 wild populations of Salicornia iranica Akhani grown around Lake Urmia, some traits including the content of chlorophyll, carotenoids, total phenol, total flavonoids, and antioxidant capacity were measured in the Department of Horticultural Science, Urmia University in 2016. The results revealed a wide range of phytochemical diversity among populations studied. The highest amount of total chlorophyll (12.05 mg/g fw) was observed in "Karkhaneh Maseh" population, while the lowest value (0.84 mg/g fw) was found in "Ghoshchi I" population. The highest (10.41 mg gallic acid/g fw) and lowest (3.7 mg gallic acid/g fw) amount of total phenol were observed in "Ghoshchi II" and "Karkhaneh Maseh" populations, respectively. Also, "Dashkhaneh" and "Aji Chai river" populations had the highest (2.12 mg quercetin/g fw) and lowest (0.18 mg quercetin/g fw) total flavonoids, respectively. The extract antioxidant capacity of different populations varied in the range of 3.16% ("Aji Chai river" population) to 70.89% ("Myghitalou" population). Cluster analysis divided the populations studied into three groups. The highest genetic distance was found between populations "Aji Chai river" and "Myghitalou". Overall, the findings of this experiment showed that the studied Salicornia iranica populations had a high diversity, especially from the viewpoint of antioxidant capacity, which can be used in the germplasm management and plant breeding of the species.

Plants, used by human, contain different compounds such as polyphenols. The phenols in food diet are important because of antioxidant and probably anticancer activity. In present research, total phenolic contents (using the Folin-Ciocalteu assay) and antioxidant capacity (using the Ferric Reducing Antioxidant Power (FRAP)) of 31 Iranian basil landraces (Ocimum basilicum L.) were measured using spectrophotometery. Linear relationship between total phenolic contents and antioxidant capacity was investigated. The similarity among studied genotypes was calculated by City block similarity coefficient and the classification of genotypes was done by the wards clustering method. Results showed that maximum and minimum total phenolic contents belonged to the landraces of Yazd with 19.84 mg/g fresh weight and Hamedan with 1.07 mg/g fresh weight, respectively. Maximum and minimum antioxidant capacity belonged to Birjand landrace with 3.73 mmol/100g, fresh weight and Shiraz II with 0.45 mmol/100g fresh weight, respectively. Phenotypic correlation between antioxidant capacity and total phenloic content in basil landraces was 0.59. According to cluster analysis, studied landraces were categorized in 3 clusters. Sanandej III and Shiraz II landraces had maximum distance from each other. It also became clear that genetic relationships among the studied populations did not match by their geographical origin. Basil populations displayed a considerable diversity for studied traits that could be useful for germplasm management and utilization into crop improvement.
