Polygonum equisetiforme, Minerals, Phenolics, Antioxidant, LC-ESI/MS


Polygonum equisetiforme is a perennial herbaceous plant thriving in the arid regions of Tunisia and widely used in health care and self-medication. The objective of the current study was to investigate the distribution of minerals, phenolic compounds, and antioxidant potentials in various plant parts including the fruit, stem, leaf, and root. The mineral composition was determined using flame atomic absorption spectrometry. The phenolic content of the samples was investigated using colorimetric assays and identified and quantified using HPLC-ESI/MS. The study found that the different parts of P. equisetiforme contain significant amounts of essential minerals such as sodium, potassium, calcium, magnesium, copper, zinc, and iron. The leaf and root extracts had high amounts of polyphenols, flavonoids, and tannins. Through LC-ESI-MS analysis, eleven flavonoids and eight phenolic acids were characterized. The most abundant compounds were gallic acid, quinic acid, catechin (+), and hyperoside. The findings suggest that different parts of P. equisetiforme are valuable sources of essential minerals and phenolic compounds, which can have potential health benefits.
