“…The sample squeezed-washed with salt recorded the highest value and this is due to the salt concentration used in the process. The iron content of V. amygdalina obtained in this work is between 6.01 and 21.39mg/100g and compares favorably with those obtained by [13] for V. amygdalina and V. calvonana var bitter as well as those obtained for A. hybridus, L. occidentalis and Lycopersicon esculentum [25]. Iron is an integral constitutuent of haeme, of haemoglobin, myoglogbin and cytochromes [11] it is also important in the transport of oxygen in blood.…”

Abstract:Bitter Leaf is a vegetable that is widely consumed and cherished in South-Eastern Nigeria. Palm oil, Potash, Salt and boiling process was used in the squeeze-washing at 3 pre-processing methods of squeeze-wash and periods of 3 to 8 minutes. The percentage retention and losses of mineral and antinutrient increased simultaneously during squeeze-washing. Copper, magnesium, calcium and antinutrient had retention of 55 to 100% for samples squeezed-washed with palm oil than the other squeeze-washed samples. This could be due to rigidity of the cells which did not allow much nutrient leached into the squeezed leaf/water; whereas, the loss of mineral and antinutrients was practically of the same magnitude (27.3 to 80.5%) in all the samples. Loss of minerals and antinutrients was observed to be influenced directly by the cause-and-effect of disintegration changes which usually leads to softening due to the severity of the squeeze-washing on the bitter leaf instead of cellular composition or level of minerals and antinurients initially present. The results are discussed in relation to traditional commercial practice of bitter leaf processing.

“…The value of calcium content of the bitter leaf sample (13.11+0.99mg/100g) obtained (Table4.3) is similar to the value reported for V. amgydalina by [13]. The value is lower than the values reported for V. amgydalin and M. charantia by [7], though it is higher than the Ca value reported for A. hydrides by [3].…”

The present study was emphasized on low input technology entitled "Evaluation of five botanical powders against maize weevil, Sitophilus zeamais (Motsch.) (Coleoptera: Curculionidae) on maize (Jibat variety) under laboratory condition", thereby decreasing the loss of maize in storage. Leave powder of five botanical used at four doses such as 2, 5, 8 and 11% weight by weight with maize seeds were evaluated in completely randomized design. The data was taken within 24, 48, 72 and 96 h after treatment application. The botanical powder caused medium to maximum mortality of adult S. zeamais, Calpurnia aurea powder caused high adult mortality with mean 36.67 and 63.33% by doses of 2 and 11% (w/w) within 96 h, respectively. Leonotis ocymifolia, 46.67 and 56.67% at rate of 2 and 11% (w/w) caused high mortality next to C. aurea. While Eucalyptus globules 30.00 and 50.00% at rate of 2 and 11% (w/w), Vernonia amygdalina and Justica schimperiana caused low to medium adult mortality when compared with untreated control, but Malathion 5% dust at a rate of 0.1% caused 100% adult mortality within 24 h. Therefore, since these botanicals have no any adverse effects on the seeds and safe to the environment, they are recommended for future usage in storage grains to control of S. zeamais.
