The stress contributes to the pathogenesis of inflammatory diseases. Synthetic antioxidants like butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT) and ascorbic acid, are used in curtailing the menace of the stress. Their potential depends on the type of phytochemicals in the oil. It is on this basis this study aimed at isolating, characterizing and investigating antioxidant potential of rind essential oil of C. reticulata. To achieve this aim, 500g of fresh rinds of C. reticulata were pulverized and hydro-distilled for three hours. GC and GC-MS analysis of the oil revealed the abundance of hydrocarbon monoterpenoids (96%). The most abundant compounds in the oil were D-limonene (82.4%), γ-Terpinene (9.4%) and β-Myrcene (2.2%). The oil exhibited antioxidant activity, with IC50value (10.73μl/ml), which was lower to the acti...

This generation of waste is of public health concern especially when the waste materials are deposited on dumpsites. This study assessed the helminths and heavy metal content of Awotan dumpsite in Ibadan city. Surface soils (0-15cm depth) of the dumpsite were randomly sampled at different dumpsite areas with the aid of a quadrat. Helminth content was determined using the zinc floatation method and the heavy metal concentrations of the soil were determined using Atomic Absorption Spectrophotometry (AAS). Some physicochemical properties of the soil were also determined. Results showed that the dumpsite soil was slightly alkaline with an average pH of 8.1 ± 0.2 while the overall mean electrical conductivity, temperature, moisture content and height above sea level were 545.9 ± 235.3μS/cm, 32.6 ± 2.2oC, 17.2 ± 4.8 % and 236±4.6 m res...
