The objective of this study was to assess the therapeutic potential of compounds extracted from Cnidoscolus quercifolius Pohl quercifklius preventing disease and its rational use as a herbal therapeutic tool. There was no statistically significant difference between the LME and RBME with the reference drug Eserinewhich represents a new source of bioactive compounds with potential as acetylcholinesterase inhibitor Figure 2.

Currently, this practice constitutes an amount of internalized knowledge shared among multiple users or in quervifolius traditional communities [ 1 ].

Cnidoscolus quercifolius – Useful Tropical Plants

In a study conducted with the oil from the seeds and extract from the leaves of the faveleira, Ribeiro [ 45 ] found reduced mycelial growth and germination of conidia of F.

This study did not detect alkaloids in any of the C. With the aid of a light source, the hatched larvae were attracted to the lightened vessel part and were collected with a Pasteur pipette and then transferred to a beaker with saline water.

Standing out among these auspicious outcomes are the antioxidant effects, the bactericidal and fungicidal potential, and the inhibitory effect against the acetylcholinesterase enzyme in two extracts tested, which showed no significant difference when compared with the reference quercifolous.

The excess of oxidative stress which leads to organic decay is mitigated or even prevented by antioxidants-based therapies.


These bioactive molecules exhibit a variety of biological effects, such as antithrombotic, anti-inflammatory, and anticancer effects, as a result of their antioxidant properties [ 41 ]. Preliminary Phytochemical Analysis The extracts were subjected to phytochemical screening, following the protocols described by Mattos [ 16 ].

It was the start of a series of cultural intermixes that blended the knowledge brought in by the colonizers, the slaves, and the natives. Different dilutions of the extracts 5— It stands out qudrcifolius its extraordinary drought resistance and medicinal properties. One of the first AChE inhibitors used was physostigmine, an alkaloid isolated from a plant of the Leguminosae family, although this alkaloid is no quercigolius used clinically, due to its short half-life.

To determine the biological activities the authors conducted investigation of antioxidant and antimicrobial activities, inhibition capacity of the acetylcholinesterase enzyme, and initial assessment of toxicity of the extracts. Among these is the faveleiraused in northeastern Brazil.

The results demonstrated great potential as an antimicrobial agent, an important antioxidant capacity, and acetylcholinesterase inhibition response with no significant difference compared with the reference drug. Ahmad and Beg [ 44 ] believe that the antimicrobial effect of vegetal extracts is largely due to the presence of flavonoids in their composition, thus corroborating the results found for the C.

Table 2 shows the results of antimicrobial activity of methanolic extracts of C. However, other species of the genus Cnidoscolus showed the presence of alkaloids [ 28 — 30 ]. View at Google Scholar U.

Cnidoscolus quercifolius – Wikiwand

The halos were measured and compared with the halo formed by physostigmine, a standard alkaloid. Moreover, a growing number of people are seeking traditional medicine for their primary health care. Van De Meent, K. This is a different outcome from the findings of this study, for none of the methanolic extracts of the faveleira exhibited growth inhibition of fungi of the same family.

Man has long been using plants to promote health, in the belief that they carry beneficial substances for a healthy existence. Antimicrobial assays against bacterial strains and fungi tested, using commercial drugs Chloramphenicol, Streptomycin, and Thiabendazole as a positive control, showed no growth of microorganisms. Spreading across an area of approximately thousand square km, the caatinga, an exclusively Brazilian biome, is also one of the most endangered areas in the planet.


The semiarid region of the Brazilian Northeast is known for hosting a number of native species that are under systematic exploitation in recent years, without any sustainable management, which ultimately causes the extinction of some species, thus unleashing a rural exodus. Abstract The caatingaan exclusively Brazilian biome, is one of the most endangered vegetation systems in the planet.

The present study, of crude methanolic extracts of Cnidoscolus quercifolius Pohl, has shown promising results in all tests performed. The United States and Germany rank among the biggest cnidoscolsu of natural products from Brazil.

By agar diffusion method, the LME and the RBME showed similar activity by inhibiting the growth of Enterococcus faeciumEnterococcus faecalisStaphylococcus epidermidisand Pseudomonas aeruginosawhile the RME inhibited only the strain of Staphylococcus epidermidis. All the methanolic extracts of the faveleira presented anticholinesterase activity.

Therefore, the root bark extract of Cnidoscolus quercifolius has a possibility of use for anticarcinogenic therapies. Brine shrimp lethality test of the methanolic extracts from C. Chemical tests were performed using specific reagents, observing color changes or formation of precipitate, characteristic for each class of substances.

Advanced Search Users Online: Most studies on the faveleira are targeted at its use in the agricultural and livestock fields, and very few vnidoscolus of the species focus on the area of chemistry of natural products and biological activity.
