Abstract

Decalepis arayalpathra popularly used as an effective remedy for peptic ulcer, gastric antisecretory and cancer-like afflictions with an immunomodulatory property. This study was conducted to unravel the chemical composition of the tuberous root and bioactivities of the compounds in the fractions of antioxidant activity by using large-scale multi-targeted approach, which is still unexplored. Methanolic extract (EM) and its sequential fraction (EC: chloroform extract, EEA: ethyl acetate extract, EB: butanol extract, EA: aqueous extract) were used for qualitative and quantitative evaluation of phytocompounds present in the tuberous root of the plant. The characterization of 2H4MB and chlorogenic acid by using high-performance liquid chromatography (HPLC) was also performed with the help of standard compound. The results revealed the extract to be rich in phenolics, tannins, flavonoids, carbohydrate, saponin and alkaloids. EM proved to be a compatible solvent for the extraction and corresponds to maximum numbers of phytocompounds followed by its fraction (EB, EA, EEA and EC). EM, EB and EEA were further subjected for gas chromatography–mass spectrometry (GC–MS) analysis, which revealed the presence of more than 20 different bioactive compounds. The methanolic extract and its successive fractions were also screened for the antioxidant activity using different prototype. 2H4MB and chlorogenic acid quantified by HPLC in methanol extract was 11.22 and 9.67 μg/ml respectively. The reported compound might be responsible for the potent antioxidant property of the plant. To our knowledge, this is the first report on the analysis of the chemical composition and the bioactive potential of the compounds obtained by extract of D. arayalpathra.
