Phenolic compositions, total phenolic, flavonoids and antioxidant capacity of an unexploited herb, Calligonum polygonoides L. from Thar desert

 A total of 15 phenolic compounds were  identified  and  quantified,  among which  gallic  acid  content  was  abundant, followed by catechin. Besides these, the other major phenolic compounds detected in  different  plant  parts  were  vanillic, chlorogenic  acid,  epicatechin,  coumeric acid,  catechol,  vanillic  acid,  epicatechin and syringic acid. Extremely higher values were  recorded  for  total  phenolics, flavonoids  and  antioxidant  capacity.  The values  for  phenol,  flavonoids  and  total antioxidant activity in bark extracts were higher than that of clove extract.
