The aim of the study was Identification and quantification of phenolic
compounds, total flavonoides content and antioxidant potential of flower
buds, foliages, bark and root of a perennial herb, Calligonum polygonoides
(Phog) of Thar Desert.
Methodology: The methanolic extracts of different plant parts of C.
polygonoides were subjected to LC-MS/MS (Waters Acquity UPLC-PDA, TQD)
analysis for phenolic identification and spectrophotometric assay of total
phenolic and flavonoids content and total antioxidant activity was estimated.
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.
Interpretation: The identified phenolic compounds possess
high antioxidant potential. These results provide scientific evidence for use
of C. polygonoides as safe natural antioxidant compounds in
nutraceutical and pharmaceutical industry.
