Abstract

The present study shows the results obtained by the disc-diffusion test, where the actions of the aqueous extract of the flower of Taraxacum officinale on the strain Escherichia coli AB1157 was evaluated and compared with the results of the aqueous extract of Schinus terebinthifolius Raddi. It can be observed that the extract of Taraxacum officinale presented greater significance in relation to inhibition of bacterial growth than the extract of Schinus terebinthifolius Raddi, suggesting to the extract of Taraxacum officinale a greater and better clinical relevance.

Highlights

Among the various substances are secondary metabolites, essential oils, tannins, oil-resins, terpenes, flavonoids, saponins, organic acids, and other chemical complexes [25], [26], which are evidenced by their chemical effect, since they can be used for immeasurable related research, since they present diverse properties as anti-inflammatory, antioxidants, anticancer, antimicrobial and several others that contribute to the investigation [9]
Preparation of Aqueous Extract The sample obtained from the flower of Taraxacum officinale was duly sanitized with distilled water, trimmed with scissors to match a size of approximately 1 cm2, weighed in a semi-analytical scale the amount of 500 grams and infused with 1000 mL of distilled water heated to 80 °C in a polyethylene tray for 60 minutes
As we look at the p-value alone, attention is diverted from the size of the effect

Summary

Introduction

Due to the great development of societies, plants have become an important therapeutic medium through man, since they have immeasurable biologically operative substances which allow the synthesis of countless other synthetic substances for the analysis of the diverse diseases that affect humans [21], [8].According to the progress of technology and the recent notions of sustainability that became common practice from the twentieth century, the use of plant herbal forms has increased worldwide, especially in Brazil, due to its gigantic vegetal biodiversity, which stimulates new studies in order to create new drugs that meet the therapeutic needs and are safe for human health, as well as for all biological areas [22], [21].Aiming at this aspect, some plant forms of the genus Taraxacum, popularly known as Dandelion, have long been applied in medicine and known to supplant hepatic disorders, breast cancer and uterus, acting as diuretics, choleretic, antiinflammatory [35], [23].From the Asteraceae family, of which the plant species Taraxacum officinale, popularly known as dandelion, has a global distribution, is better expressed in the temperate and subtropical regions, in approximately 1,100 genera and 19,000 species [24].Among the various substances are secondary metabolites, essential oils, tannins, oil-resins, terpenes, flavonoids, saponins, organic acids, and other chemical complexes [25], [26], which are evidenced by their chemical effect, since they can be used for immeasurable related research, since they present diverse properties as anti-inflammatory, antioxidants, anticancer, antimicrobial and several others that contribute to the investigation [9].Among the substances extracted from Taraxacum officinale are the terpene derivatives taraxerol, taraxasterol and the glycoside taraxacoside [27], in addition to sterols (ßsitosterol, stigmasterol), rubber, resins, indices of essences, fatty bodies, levulose, a galactose polyholoside and arabinose, caffeic acid, ϸ-hydroxyphenyl acetic acid, asparagine, tyrosine [21], choline, levunin and pectin [10], tannins, carotenoids, phytosterol [28], ß-amirin, flavonoids, citric acid, amino acids, saponins and inulin [27]. According to the progress of technology and the recent notions of sustainability that became common practice from the twentieth century, the use of plant herbal forms has increased worldwide, especially in Brazil, due to its gigantic vegetal biodiversity, which stimulates new studies in order to create new drugs that meet the therapeutic needs and are safe for human health, as well as for all biological areas [22], [21] Aiming at this aspect, some plant forms of the genus Taraxacum, popularly known as Dandelion, have long been applied in medicine and known to supplant hepatic disorders, breast cancer and uterus, acting as diuretics, choleretic, antiinflammatory [35], [23].
