Abstract

The herb Equisetum arvense is an herbaceous plant, commonly known as horsetail and as a medicinal plant. Its therapeutic resource is diffused intensely in the urban environment as an alternative or complementary form to allopathic medicines, therefore it is an important theme focused on medicine and popular health. In this context, the focus of the present work was to characterize the product of the tea from a manipulation form made by specialized pharmacy (M) and other natural product banking (B). The two horsetails were extracted in aqueous medium since this is the form in which the material is absorbed by the organisms. The M and B lyophilized products were preliminary characterized by infrared spectroscopy (FTIR), visible ultraviolet (Uv-vis), scanning electron microscopy (SEM) and X-ray dispersive energy (EDX). The resulting biomass adsorption (wastes) were applied in the cupric ions adsorption and the maximum adsorption capacity (Nfmax of M and B horsetail were 4.4x10-4 mol g-1 and 2.6x10-4 mol g-1 respectively.

Highlights

The herb Equisetum arvense is an herbaceous plant of Equisetopsida class, Equisetales order, Equisetaceae family and belonging to pteridófitas group, commonly known as horsetail
The focus of the present work was to characterize the product of the tea whose was extracted in aqueous medium (Since this is the form in which the material is absorbed by the organisms) by infrared spectroscopy (FTIR), visible ultraviolet (Uv-vis), scanning electron microscopy (SEM) and X-ray dispersive energy (EDX)
The great absorption capacity of the horsetail root gives it great diversity in the chemical constitution, which can be observed through the EDX

Summary

Introduction

The herb Equisetum arvense is an herbaceous plant of Equisetopsida class, Equisetales order, Equisetaceae family and belonging to pteridófitas group, commonly known as horsetail. It is originated in Europe, which has in its composition: minerals, potassium, magnesium, aluminum, calcium, phosphorus, phosphorus and sodium besides it is known as one of the plants with the highest accumulation of silica (biogenic silica) (Sola-Rabada et al, 2016). The horsetail is a ground plant with the largest amount of silica, which allows it has several applications in medicine area (Des Marais et al, 2003). Researchers believe that the anti-bacterial and antiseptic medicinal properties associated with the plant are due to the high silica content. The way how silica is found in tea can determine its property and use (Holzhuter et al, 2003; Ma et al, 2006)
