Abstract: Solanum anguivi Lam, collectively called Gnagnan in Côte d'Ivoire is an eggplant with nutritional and therapeutic potentialities. The present study was undertaken to analyze the chemical composition of berries at different stages of maturity. Data showed that at the first stage of maturity, green berries are rich in ascorbic acid (34.5 ± 1.7 mg / 100 g DM), phenolic compounds (956.7 ± 71.1 mg / 100 g DM), iron (467.7 ± 1.8 mg / 100 g DM), magnesium (404.6 ± 16.3 mg / 100 g DM) and potassium (2059.7 ± 22.3 mg/100 g DM). However at the last stage of maturity, red berries are rich in proteins, cellulose, total sugars, fat and potassium with values of 22.53 ± 2 g/100 g DM, 19.12 ± 0.4 g/100 g DM, 3.7 ± 0.2 g/100 g DM, 2.7 ± 0.2 g/100 g DM and 2290.8 ± 22.2 mg / 100 g DM respectively. Thin layer chromatography revealed the presence of glucose, ribose, xylose, arabinose and fructose at all maturity stages. Excepted alkaloids and gallic tannins, the phytochemical sorting revealed that Gnagnan contain several pharmacological components. According to the maturity stages, orange and red berries showed a higher content in sterols and polyterpens, flavonoids and saponins. The green berries contain most of polyphenols, catechin tannins and quinons. As to yellow berries, they are rich in polyphenols and catechin tannins. Data of our study may enhance clinical research on the nutritional and pharmacological properties of S. anguivi Lam.

Abstract: The article describes the main principles of stepped diet therapy of acute intestinal infections in children developed on the basis of nutritive support staging, depending on patients’ age, stage and severity of disease. Significance of functional food products for diet therapy tactics in patients with mild and moderately severe forms of infection is demonstrated.

Abstract: Aflatoxins, produced by some aflatoxigenic strains of the Aspergillus species, are known as potent carcinogenic. Aflatoxin biosynthesis involves lipid peroxidation with the presence of fatty acid hydroperoxides promoting aflatoxin production. Methyl jasmonate (MeJA) derives from α-linolenic acid and is a plant growth regulator, produced as a response to stress, such as by environment or pathogen attack. This study reports on the effect of MeJA added on A. parasiticus growth and AFB1 production in caper, an edible plant of Greek origin used as condiment. AFB1 determination in caper was performed by using HPLC-FD. Five different concentrations of MeJA, 10-6 Μ, 10-4 Μ, 10-3Μ, 10-2 Μ, and 10-1 Μ, were added in caper samples and the kinetic of the AFB1 production by A.parasiticus was studied for an incubation period of 15 days. Results revealed that MeJA affects AFB1 production by A. parasiticus in a dose-dependent manner. MeJA at a concentration of 10-6 M stimulated AFB1 production after the 9th day of incubation. MeJA at concentrations of 10-4 M and 10-3M decreased moderately AFB1 output. Finally, MeJA added to the caper samples at a concentration of 10-2 Μ and 10-1 Μ inhibited AFB1 by 97.74% and 98.42% respectively on the 12th day of observation.
