Evaluation of phytochemical constituents and antioxidant properties of <em>Trianthema portulacastrum</em> Linn

Abstract

Trianthema portulacastrum Linn. (Biskhapra) is an annual herb belongs to the family Aizoacae, which is used to treat for many oxidative stresses related diseases. The current study was done to characterize the organoleptic and proximate characteristics and to estimate the phytochemical components and to investigate antioxidant activity of aqueous extracts of leaves of the plant. The results showed that total phenolic, flavonoids and tannin content are 112.96±0.93 mg Gallic Acid Equivalent/g Dry Weight, 164.84±0.91 mg Quercetin Equivalent/g Dry Weight and 11.79±0.37 mg Tannic Acid Equivalent/g Dry Weight, respectively. Total protein and amino acids contents are 193.56±2.68 mg BSA Equivalent/g Dry Weight and 128.79±3.19 mg Tyrosine Equivalent/g Dry Weight, respectively. Total polysaccharide, lipid and ascorbic acid content are 117.85±6.20 mg Dextrose Equivalent/g Dry Weight, 9.10% and 21.13 mg Ascorbic Acid Equivalent/g Fresh Weight, respectively. Inhibition percentage of antioxidants assays such as DPPH, ABTS and H2O2 are 80.68±0.83%, 77.27±0.93% and 72.83±0.86%, respectively. From the results may be concluded that the leaves of the plant possess biologically active secondary metabolites that can be highly applicable for the healing purposes of oxidative stress related diseases.
