“…These results are similar to the work of Gueye, et al [9] in the Kédougou region of eastern Senegal, which showed the repellent effect of the dried leaves of Hyptis spicigera and Hyptis suaveolens against the insect pests of cereals Tribolium castaneum and Sitophilus zeamais in traditional granaries for a period 7 months. These results are also consistent with the work of Ukeh, et al [22] conducted in Obudu, South-East Nigeria, which showed that 10% (w / w) powders and Aframomum melegueta and Zingiber officinale (Zingiberaceae) essential oils significantly reduce the progeny of Coleoptera Sitophilus zeamais type in traditional African granaries over a period of about 3 months. In addition, the work of Konan, et al [18] showed the beneficial effect of L. multiflora leaves on the merchantability of stored cowpea grains in triple bagging systems.…”

“…In addition, more than 300 million people in sub-Saharan Africa rely on maize as a source of food and subsistence [1], [2]. Of the twenty-two (22) countries in the world where maize is the highest percentage of caloric intake in the diet of populations, sixteen (16) are in Africa including Côte d'Ivoire [3]. In this country, maize (Zea mays L.) is distinguished by its very large extension of its cultivation area due to its great adaptability [4].…”

The aim of study was to evaluate merchantability quality of stored maize in triple bagging with biopesticides. Maize grains were collected in March 2016 in the north of Côte d’Ivoire. The fresh leaves of Lippia multiflora and Hyptis suaveolens were collected and dried in sunlight for 7 days in the center of Cote d'Ivoire. Triple bags were bought in Abidjan market. All this material was sent to the Laboratory of Biochemistry and Food Sciences, Félix Houphouët-Boigny University, Côte d’Ivoire, to perform the experiment. Ten treatments were obtained for the experimentation. The first treatment was conservation of 50 kg of maize grain in a polypropylene bag. The second treatment was conservation of 50 kg of maize grain in a PICS bag. The other eight treatments were carried out with PICS bags each containing 50 kg of maize grain and different proportions of chopped leaves Lippia multiflora and Hyptis suaveolens. A central composite design was used for sample constitution. Thus, a control group with polypropylene bags (TPPB0), a control group in PICS bags without biopesticides (TPB0) and 8 experimental lots of triple bags noted TB1 containing 0.625 kg L. multiflora and 0.625 kg H. suaveolens, TB2 with 0.40 kg of L. multiflora and 1.60 kg of H. suaveolens, TB3 with 1.60 kg of L. multiflora and 0.40 kg of H. suaveolens, TB4 with 0.10 kg of L. multiflora and 0.40 kg of H. suaveolens, TB5 with 0.40 kg of L. multiflora and 0.10 kg of H. suaveolens, TB6 with 2.5 kg of L. multiflora and 2.5 kg of H. suaveolens, TB7 with 1.25 kg of L. multiflora and TB8 with 1.25 kg of H. suaveolens have been used. Changes in moisture, damages and weight losses were studied. The results show moisture levels (from 09.02±0.11% to 12.07± 0.06%), weight loss (from 0.49±0.02% to 2.54±0.07%) and damage (from 0.99±0.02% to 3.96± 0.01%), corn stored in triple bagged bags with different proportions of biopesticide were significantly lower than those recorded in the Polypropylene woven sample bag (TPPB0) and in the triple bagged control bag during the storage period. The results obtained indicate stability in the quality of maize stored for 18 months in triple bagged bags containing different proportions of leaves of L. multiflora and H. suaveolens. A proportion of 5% of the mixture of leaves of L. multiflora and H. suaveolens (2.5 kg of L. multiflora and 2.5 kg of H. suaveolens) in triple bagged bags is recommended for a better preservation of the merchantability of the stored maize grains kernels. Storage of maize grains in PICS bags with the leaves of L. multiflora and H. suaveolens appears as a method of effective and inexpensive conservation to ensure the merchantability quality of maize.

“…[17,18] There are also numerous reports on insecticidal activity of the essential oils and other products from Zingiber species. [19][20][21][22] Amomum villosum Lour. belongs to the Zingiberaceae family and is widely distributed in the south of China.…”

The Amomum villosum essential oil was obtained from hydrodistillation and was investigated by GC-MS. The main constituents were bornyl acetate (51.6%), camphor (19.8%), camphene (8.9%) and limonene (6.2%). Insecticidal toxicity of the essential oil was evaluated in this study. It showed that the essential oil possessed contact toxicity against Tribolium castaneum and Lasioderma serricorne (LD 50 = 32.4 and 20.4 μg/adult). Three monoterpenoids camphor, camphene and limonene showed strong fumigant toxicity against T. castaneum (LC 50 ＜ 2.3, LC 50 ＝ 6.2 and 6.2 mg/L air). In addition, repellency of the essential oil was also evaluated. Data showed that the essential oil and all four compounds had repellent activity against T. castaneum and L. serricorne at high concentration (78.63 nL/cm 2). But with the decrease of concentration, they showed a different degree of attractant properties.

“…The aqueous seed extract exhibited anti-inflammatory and peripheral analgesic activities (Umukoro and Ashorobi, 2001). It was used for medicinal purposes due to its antiinflammatory and antimicrobial activities, to relieve dental pains, asthma and body weakness, enhance body activities and preservation of grains (Ukeh et al, 2011). The sharp and peppery taste of the seeds is reportedly caused by the presence of aromatic ketones: 6-paradol, 6-gingerol and 6-shogaol as part of its content (Sugita et al, 2013).…”

The hepatotoxic effects of the seeds of Aframomum melegueta (Grains of paradise), a spice were studied in Sprague-Dawley rats. Individual rat groups received sub-chronic exposure of the methanol seed extract at 300 mg/kg for 7, 14 and 21 days respectively. Liver toxicity was evaluated with assay of circulating serum aspartate aminotransferase (AST), alanine aminotransaminase (ALT), alkaline phosphatase (ALP), albumin, total bilirubin concentrations and histopathology of the liver of treated experimental rats. Serum levels of AST significantly (p<0.05) increased progressively in extract-treated rats compared to the control from day 7 till the termination of the study (day 21). However, serum ALT, ALP and total bilirubin levels of test rats were only significantly (p<0.05) elevated relative to the normal on days 14 and 21 of the investigation. The dose (300 mg/kg) of extract produced AST value of 55.8±3 µL -1 while the control was 32.2±1.9 µL . The serum albumin levels of extract-treated rats were however, comparable with that of the normal rats throughout the study period. Histopathology of the rat livers revealed mild focal necrosis of hepatocytes at day 7, moderate multifocal areas of hepatic necrosis at day 14 and severe, diffused necrosis of hepatocytes at day 21 of treatment with the extract. The results demonstrated that the methanol seed extract of A. melegueta was potent in inducing liver toxicity at the tested dose (300 mg/kg). Maximal caution should therefore be imbibed in prolonged excessive use of the plant seeds as spice in delicacies.
