Organochlorine pesticide residues in dried cocoa beans obtained from cocoa stores at Ondo and Ile-Ife, Southwestern Nigeria
Levels of organochlorine pesticides (OCPs) were determined in dried cocoa beans obtained from cocoa produce stores at Ondo and Ile-Ife, Southwestern Nigeria. Cocoa beans samples were sun dried to a constant weight, pulverized and soxhlet extracted with dichloromethane to obtain the OCPs. Qualitative identification and quantitative evaluation of the extracted OCPs after clean-up on silica gel we...

متن کاملIsolation of dimeric, trimeric, tetrameric and pentameric procyanidins from unroasted cocoa beans (Theobroma cacao L.) using countercurrent chromatography.
The main procyanidins, including dimeric B2 and B5, trimeric C1, tetrameric and pentameric procyanidins, were isolated from unroasted cocoa beans (Theobroma cacao L.) using various techniques of countercurrent chromatography, such as high-speed countercurrent chromatography (HSCCC), low-speed rotary countercurrent chromatography (LSRCCC) and spiral-coil LSRCCC. Furthermore, dimeric procyanidins...
متن کاملAssessment of Heavy Metals Mobility in Selected Contaminated Cocoa Soils in Ondo State, Nigeria
Phytophtora pod rot is currently the most important limiting factor in the Nigeria cocoa Industry with a total losses of 30-90% crop loss. To overcome this problem, Nigerian cocoa farmers solely use copper-based fungicides to control the disease. Copper being a metal is not biodegradable. Hence, it accumulates in the soil as a result of continual use. Heavy metals are potentially toxic to soil ...
