Abstract
Plants are rich sources of phenolic and flavonoid compounds which are important natural antioxidants. Antioxidants today are important in terms of medicine because they reduce oxidative stress in the cells and therefore are useful in the treatment of many cardiovascular diseases and inflammatory diseases. Chenopodium is a herbal medicine (family, Chenopodiacea) that is used for treat of hemorrhoids, sore throats, eye and liver disorders. The objective of this research was to study of phenolicand flavonoid compounds of three organs (leaves, stems and fruit) of 3speciesof Chenopodium (Ch.ficifolium, Ch. sosnovskyi, Ch. novopokrovskyanum) in Sistan region. Phenolic and flavonoid contents were measured by Folin- Ciocalteu and Aluminum Choroids methods, respectively. In addition, the antioxidant activity was studied by DPPH radical-scavenging activity and ferric reducing/antioxidant power (FRAP) methods. Anthocyanin content evaluated by Wager method. Tthe essential oil of was an Ch. Sosnovskyi fruit alyzed by GC / MS. In general, the results showed that phenol and flavonoids had the highest levels in the fruits and leaves of the three species, and the leaves of Ch. Sosnovskyi has a highets level of phenol and flavonoid than the other two species. The highest amount of anthocyanin was observed in leaves Ch. ficifolium. GC / MS analysis showed 56 compounds in leaves of Ch. Sosnovskyi. The highest amount of essentialoil was Tetradecan (10.54%), Hexadecane (8.47), Dodecane (7.74), Octadecane (5.97), 3-Methyl-4- isopropylphenol(4.94) respectively.Also leaves of Ch. Sosnovskyi have the most antioxidant activity. In general, leaves of Ch. Sosnovskyi as rich source of phytochemicals and high antioxidant capacity, suggest for pharmaceutical use.
