Total phenol, flavonoid contents and antioxidant activity of Gundelia tournefortii L. in different phenological stage and habitats of North East of khozestan province

Gundelia tournefortii L. is an endemic valuable forag - medicinal plants, belongs to Asteraceae family. This study was evaluated to total phenol, flavonoide content and antioxidant activity of Gundelia tournefortii L. in different stages of growth from four habitats in north east of Khozestan province (900 m). The aerial parts of plant were collected from 4 natural habitats (Dare-Khorson, Shahzade Ahmad1, Shahzade Ahmad2 and Dehdez) in three stages: vegetative, flowering and seed dispersal. Total phenol (TP) and total flavonoids (TF) of methanol extracts were measured by spectrophotometry and antioxidant activity by scavenging free radicals of DPPH and then were analyzed based on multivariate variance (MANOVA). Results were showed that in all habitats, plant parts and phenological stages of plant had significant effect on antioxidant activity, total phenol and flavonoid contents of plant in 99 percent (P
