As queimaduras são as causas mais comuns de lesões cutâneas. Para dinamizar o processo de cicatrização são utilizados polímeros naturais em substituição aos polímeros sintéticos. A pectina e a galactomanana de jucá (Caesalpinia ferrea) e o alginato reticulado com cálcio são atóxicos e biodegradáveis. E juntamente com os extratos dos frutos do jucá apresentaram propriedades bactericidas e toxicidade baixa, agem ...
This study aimed to establish a nutritional ranking of 30 genotypes of cowpea (Vigna unguiculata L. Walp). The results showed the proximate composition varies among genotypes in protein (20–30%) and dietary fiber contents (20–35%), in protease inhibitors (2–4 UI/mg protein), lectin (40,000–640,000 UH/kg meal) and essential amino acid levels, in vitro protein digestibility (30–40%) and in the apparent concentrat...
Anacardic acid, cardanol and cardol, the main constituents of natural cashew nut shell liquid (CNSL), were obtained by solvent extraction and assayed for antioxidant, larvicidal and antiacetylcholinesterase activity. Their relative percent composition was obtained by HPLC analysis. Antioxidant activity was assessed using the DPPH and ABTS•+ tests, which showed cardanol as the most active, followed by cardol and...
Environmental toxicity, low biodegradability and increased resistance in agricultural pest insects and in insect vectors of diseases to insecticides traditionally used for their control have encouraged the development of chemical alternatives with greater specificity and biodegradability especially from plants. In this way, the present study aimed the purification, characterization and evaluation of activity to...

A modification of the sensitive agar diffusion method was developed for macro-scale determination of alfa-amylase. The proposed modifications lower costs with the utilisation of starch as substrate and agar as supporting medium. Thus, a standard curve was built using alfa-amylase solution from Aspergillus oryzae, with concentrations ranging from 2.4 to 7,500 U.mL–1. Clear radial diffusion zones were measured af...
