The antioxidant capacity, total phenolic content and phenolic compounds of Plantago coronopus L. subsp. coronopus in naturally distributed in Akdoğmuş-Siirt

Abstract

Name probably for Plantago coronopus L.; in reference to the shape of basal leaves [1]. Plantago coronopus, commonly known as buckshorn banana (“diabelha” in Portugal), is a medical halophyte belonging to the Plantago L., the largest of the Plantaginaceae family [2]. Plantago will be those the vast majority paramount variety of the Plantaginaceae crew, What's more, will be utilized within customary prescription around the reality for separate purposes. Plantago coronopus L., Plantago major L., Plantago media L. also Plantago lanceolata L. would a large portion regularly utilized species of Plantago for a customary solution to turkey [3]. There would 28 taxa of the class Plantago did turkey and two of them are endemic [4]. In this study, extracts of Plantago coronopus L. subsp. the coronopus taxon was prepared with methanol (%80) solvent. Total phenolic contents were assessed by Folin Ciocalteau's method and were found as 32.66 mg gallic acid /mL extract. The antioxidant activity was determined by using DPPH methods as 87.26%. And also, the chemical composition of the phenolic compounds was determined with LC-MS/MS instrument. As a result, 12 phenolic compounds were quantitatively detect, among the 27 phenolic compounds analyzed. These; Quinic acid (618±29.66 mg g -1 ), Malic acid (809.88±42.92 mgg -1 ), tr-Aconitic acid (4.49±0.22 mgg -1 ), Gallic acid (2.73±0.14 mgg -1 ), Protocatechuic acid (24.11±1.73 mgg -1 ), Tannic acid (33.01±1.68 mg g -l ), tr-Coffeic acid (11.06±0.58 mg g -l ), Vanilin (9.18±0.45 mgg -1 ), p-Coumaric acid (61.16±3.12 mgg -1 ), Kaempferol (43.64±2.27 mgg -1 ), Luteolin (5.35±0.37 mgg -1 ) and Apigenin (8.27±0.44 mgg -1 ).
