“…However, data in the literature associating larvicidal or insecticidal action with proteolytic activity are scarce. Most of the available data deal with insecticidal plant proteins such as lectins, ribosome-inactivating proteins, enzyme inhibitors, arcelins, chitinases, ureases and modified storage proteins (Carlini & Grossi-de-Sá 2002). On the other hand, Pechan et al (2002) have described a correlation between the impaired growth of caterpillars and a cysteine proteinase present in some Maize (Zea mays L.) lines that are resistant to feeding by a number of lepidopteran species.…”

“…Screening of plant extracts for deleterious effect on insects is one of the approaches in the search of novel biological insecticides [1]. Insecticidal activity of many plants against several insects has been demonstrated [2,3]. Seed as well as foliar extracts of several plants have been reported to have toxic and potent growth reducing activity to insects [4].…”

In the present study, the crude ethanol extracts of Calotropis procera and Annona squamosa leaves have been screened for their larvicidal activities against Musca domestica. The third instar larvae of housefly were treated with the different concentrations of both the extracts by dipping method for 48 h. The LC 50 values of the extracts of C. procera and A. squamosa leaves were found to be 282.5 and 550 mgl -1 , respectively. The phytochemical analysis of these extracts suggested presence of alkaloids as the major component. The larvae were exposed to 5 and 10% concentrations of the LC 50 value of each extract along with their control sets to evaluate their effect on metamorphosis, nucleic acid and protein content in different developmental stages. The leaf extract of C. procera was found to be more active in terms of insecticidal potential. The data indicate that the leaf extracts of these plants may be utilized as the probable candidates for the development of bioinsecticides to control the population of Musca domestica as safer and economic alternatives to the synthetic insecticides.

“…Technically, the protein bands present in the range of 5-25 kDa suggest the presence of inhibitors of serine peptidases type Kunitz, Bowman-Birk and 2S albumin which has been reported in the scientific literature (Carlini & Grossi-de-Sá, 2002;Ruan et al, 2011). The band near the molecular weight of 11 kDas was more abundant in both phases, this being apparently very similar to the protein that shows 40% activity against trypsin, purified from Pequi seed, called 2S albumin (Costa, 2012).…”

Anti-nutritional factors and digestibility of protein in Cayocar brasiliense seeds

et al. 2017

The Brazilian Cerrado presents a wide variety of natural products, including the Pequi (Caryocar brasiliense). The important factor that determines the dietary and nutritional ideality of protein is degestitibility. This work aims to evaluate the protein digestibility of Pequi seeds and the presence of anti-nutritional factors. The protein Pequi almonds were extracted, toasted and untoasted. Evaluation digestibility was structurally characterized by SDS-PAGE 15%, which can be used to analyze simulated gastric fluid (SFG) and digestion in intestinal fluid (SFI) in the presence of pepsin and trypsin/chymotrypsin. The extract from Pequi almonds showed inhibitory activity and was not detected hemagglutination. The intensity of the bands according to 2S albumins, after heat treatment, did not decrease in comparison to the condition native, significantly. In the crisp crude extract, which was incubated under SGF and SIF, the intensity of the corresponding bands at 8 and 3 kDa was resistant to SGF and indigestible after 4 hours under SIF. The characterization of Pequi almonds demonstrated that the product of the crude extract has anti-nutritional factors, which were confirmed by evaluating digestibility.Keywords: Caryocar brasiliense; almonds; in vitro digestibility; 2S albumin; peptidase inhibitor; lectins.Practical Application: The study of anti-nutritional factors identification is very important because of its inactivation on food industry and it can also be used to avoid allergy due to them.
