“…Little is known about the properties of this plant in reducing plant-parasitic nematodes. In one of the few studies, Schwengber et al (2017) reported the effect of the essential oil of this plant against Pratylenchus zeae in the greenhouse. Borges et al (2018) also related to the suppression of root-knot nematode by S. terebinthifolius essential oil.…”

Nematicidal substances have been identified from plants and are potentially useful for the management of plant-parasitic nematodes. Cabralea canjerana, (Meliaceae) and Schinus terebinthifolius (Anacardiaceae) produce bioactive compounds during their secondary metabolism and little is known about the effect of such substances on plant-parasitic nematodes. In the present study, we assessed the effect of aqueous and ethanolic extracts of C. canjerana and S. terebinthifolius at 1% (m:v) and purified substances from C. canjerana (gedunin, ocotillone, cabraleadiol, a mixture of ocotillone + cabraleadiol and a mixture of shoreic acid + eichlerianic acid) on hatching and mortality of Meloidogyne incognita juveniles. Aqueous extracts of C. canjerana fruits and seeds reduced hatching by 70.3 to 95.7%. Aqueous extracts of S. terebinthifolius fruits killed 42.8 to 77.1% of juveniles. The purified substances of C. canjerana inhibited the hatching of M. incognita from 57 to 90% and did not increase the mortality of juveniles. Therefore, C. canjerana extracts and its purified substances reduce M. incognita hatching and aqueous extracts of S. terebinthifolius kill J2 of this nematode.

“…For plants, essential oil and oleoresin present an important defense mechanism, as they contain capsaicin, with antifungal, bactericidal, antiviral, insecticidal, larvicidal and molluscicidal action (Pereira et al, 2016;Tomazoni et al, 2017;Schwengber et al, 2017).…”

Capsaicinoids are natural compounds characteristic of peppers that condition their spicy flavor. The fruits are widely used in the food, pharmaceutical and cosmetics industries as they have anticancer, antioxidant and antibacterial properties. Extracts are normally obtained using organic solvents as they are efficient in transporting bioactives such as capsaicin. Therefore, the present work aimed to extract and quantify the capsaicinoids found in fruits and seeds of pepper accessions of the genus Capsicum from the active germplasm bank of the Instituto Federal do Espírito Santo. The extraction process was carried out using 99.8% P.A. ethanol as solvent using Soxhlet equipment, and for quantification of capsaicin a UV-Vis spectrophotometer was used at 280 nm. The oleoresin yield was 33% in relation to the dry pepper mass. To determine the amount of capsaicin in the sample, a calibration curve was constructed with the standard ~95%. The concentrations of capsaicins in the extracts were found in the ranges of 97.81 and 419.79 mg. g-1. The analysis of variance presented a coefficient of variance of 0.3%, which means that no difference occurred at 5% significance using the Tukey test. The samples of the Ifes 100 and Ifes 71 accessions, of the species Capsicum baccatum var. pendulum and Capsicum frutescens, respectively, with the highest amounts of capsaicins per mass of extract and the accessions Ifes 56 and Ifes 62 presented the lowest amounts of capsaicin, both corresponding to the species Capsicum chinense. The Soxhlet extraction method, with organic solvent ethanol, was efficient in transporting capsaicinoid compounds, presenting a yield of around 33% in the formation of oleoresin. The process of quantifying capsaicinoid compounds proved to be efficient, identifying the presence of the active capsaicin in the accesses analyzed, identifying genotypes of interest to be explored in crop improvement.
