Sitophilus zeamais is one of the most economically impactful pests, attacking various grains and processed foods. Control this insect has been achieved using synthetic insecticides, exacerbated careless use which led to development resistant populations, toxicity non-target organisms environmental contamination. In study, Piper corcovadensis leaf essential oil (PcLEO) its major compound, 1-butyl-3,4-methylenedioxybenzene (BMDB), were investigated as alternative insecticidal agents against S....
Abstract This is the first report on chemical composition of essential oil flowers white lotus ( Nymphaea , Nymphaeaceae). The relative configuration its main constituent, diterpenoid dolabella‐3,7,18‐triene, was determined to be (1 R ,3 E ,7 ,11 S ,12 ) basis DFT DP4 13 C‐NMR quantitative shift analysis. Both (LC 50 < ppm) and aqueous solution (55% larvae mortality in 50% (v/v) concentration) obtained through hydrodistillation extraction exhibited a satisfactory larvicidal effect against...
The traditional analysis of variance (ANOVA) an experimental design is not efficient for evaluating the effect all constituents simultaneously in gas chromatography mass spectrometer (GC-MS). This work evaluated influence temperature, pressure, extraction time and their interactions to obtain essential oil from Piper corcovadensis using supercritical fluid (SFE). For this purpose, ANOVA - principal component (ANOVA-PCA) was used assess process parameters on each constituent extracted oil....
