Caesalpinia pyramidalis

The third and fourth groups G3 and G4 were drenched with CP extract 2. All the contents of this journal, except where otherwise noted, is licensed under a Creative Commons Attribution License.

The parasitological analysis indicated that the CP extract exhibited anthelmintic activity in naturally infected goats, whose effectiveness was evidenced by the reduction in FEC as compared to the negative control group. The mechanisms whereby the consumption of certain plants and plant extracts can affect parasite cycle both in vitro and in vivo are unknown. Van Leeuwen, and W. In the study of humoral immune response, antibodies of two immunoglobulin classes were investigated: Although controversial, this is consistent with other experimental findings with helminthes, in which no notable alteration in these parameters was found [ 19 ].

The chloroform extract of the trunk wood gave 4,4′-dihydroxy-2′-methoxychalcone, – -syringaresinol, and methyl gallate.

Indexed in Science Citation Index Expanded. However, the analysis of HMBC spectrum data for the linkage between the flavonoid units was conclusive. Moreover, the serum anti- Haemonchus antibody responses presented significant increases in G2 and G3, whereas G4 yielded an average OD of 1. An increase in IgA levels was observed in G3 and G4during the experimental period, suggesting that it was stimulated by the extract administration.

This work aims at evaluating the anthelmintic effect of CP extract in vivo against GIN natural infected goats in order to confirm the benefits. In addition, serum IgA levels had a significant response in the 5. Thus, the linkage at C-6 of the flavone unit was established due to the presence of methine carbon signals at d Agathisflavone and other biflavone derivatives have been tested as topoisomerase inhibitors. IgA levels could reflect the degree of sensitisations of the animal.

Therefore, economic losses caused by GIN are related to decreased production, treatment costs, and even animal death in small ruminant production [ 2 ]. However, gastrointestinal nematodes GINs remain one of the greatest limiting factors to successful and sustainable livestock production worldwide [ 1 ]. On the other hand, the flavanone unit was recognized by its characteristic 13 C signals, which were attributed to a carbonyl group as well as to the C-2 and oxybenzylic carbon of ring C.

The ethanol extract showed anti-Helicobacter pylori activity, with inhibition halos of In treated animals with CP, there was noted a significant reduction of FEC and Blood Sampling Faecal and blood samples were recovered at day 0 and at 30 and 60 days after treatment. Phenolic compounds were also evaluated in vitro for their antimicrobial activity to control pathogenic bacteria [ 41727 ]. The genus Caesalpinia Caesalpinioideae, Fabaceaecomprised of tropical or subtropical trees or shrubs, contains more than species worldwide.

Similarly, the extract does not appear to have influenced the change of weight in animal groups during the experimental period.

Thus, this spectrum showed single hydroxyl bounded group signals at d Therefore, further experiments with infected animals are essential to evaluate the best dose of the extract to be administered and still offer subsidies for the development of new drugs for the treatment of livestock against gastrointestinal nematodes. Compound 4 4,4′-dihydroxy-2′-methoxy-chalcone was identified by NMR analysis. Its control based on the use of commercial anthelmintics is no longer considered sustainable due to an increased prevalence of GIN resistance as well as chemical residue and toxicity problems [ 2 ].

Parasitological and Zootechnical Measures FEC determination was carried out in four regular intervals, initially, two weeks before assay, with the aim at tracing and randomly distributing the animals into four groups at day zero, prior treatment extract and doramectinand then at days 30 and 60 after treatment in all groups. According to Siqueira et al. In conclusion, the results showed that CP provoked a protective response in infected animals treated with them.

The 1 H NMR spectrum of caealpinia also corroborated to propose the biflavonoid structure and the linkage between the flavanone and flavone units. Table of Contents Alerts.

The monitoring was carried out between March and May, coinciding with the end of the dry season and beginning of the rainy period. Under the experimental conditions, the results with C. Basically, the counts remained stable throughout the experiment without any difference for all groups. June 10, Published on the web: The chloroform extract of the leaves of Caesalpinia pyramidalis Caesalpinioidea, Fabaceae yielded the new biflavonoid named caesalflavone, as well as podocarpusflavone A, agathisflavone, apigenin and kaempferol.

In semiarid Brazilian region, haemonchosis causes severe economic losses in livestock pyramifalis e. Introduction Goat herding is an attractive source of income for farmers in northeastern Brazil.

PCV values did no change during experimental period. From the present results and considering the significant reduction in the egg output, this study indicates that IgA may play a role in the parasite control. For leukocyte counts, similar results were observed in caeszlpinia posttreatment groups and also no significant differences were seen in the eosinophil values in blood when compared to the negative and positive control.

Once some plants have been reported to pramidalis anthelmintic properties, attributed to secondary metabolites e. On the other hand, the bonded hydroxyl d NMR data is in agreement with mass spectrum and showed that the acesalpinia is made up of flavanone and flavone units Table 1. The in vivo trials on the anthelmintic activity of CP extract showed significant reduction in the mean faecal egg count throughout experimental period Figure 1 a.
