This study was embarked upon to evaluate the efficacy of aqueous extracts of Senna tora leaf against Perenospora parasitica, causing downy mildew on cabbage. Phytochemical analysis of the leaf extracts revealed the presence of some secondary metabolites (Tannins, Saponins, Flavonoid, Glycosides, Alkaloids, Phenolic compounds and Carbohydrates) which have been reported to have antimicrobial effects. Assays were performed using extract concentrations of 1000, 500, 250, 125 mg/ml by agar well diffusion technique. Results obtained, revealed a significant difference in diameter of mycelial zone of inhibition between the concentrations. Highest zone of inhibition was recorded at 1000 and 500 mg/ml (20 and 15 mm) respectively. Minimum Inhibitory Concentration (MIC) and Minimum Fungicidal Concentration (MFC) were determined and recorded at 250 mg/ml. The antifungal screening revealed that the extract exhibited inhibitory activities at varying concentrations against the downy mildew pathogen. These activities observed could be attributed to the presence of active metabolites contained in the extract.Keywords: Aqueous leaf extract, Downy mildew, Perenospora parasitica and Senna tora

Edible Roots

Background: Daucuscarota sativus L. (Apiaceae) commonly known as ‘carrot’ is a multipurpose herb cultivated in different parts of the world for its edible roots, juice, oils and leaves. Carrot root as well as its leaves has been credited with many medicinal properties, including cleansing of the intestine and maintenance of acid-alkaline balance in the body. Carrot leaves also known as carrot tops or carrot greens have been used locally as a decoction for healing mouth sores, and in some cases, mixed with honey to clean festering wounds. The present study was therefore designed to evaluate the possible gastro-duodenal protective property of Daucuscarota sativus (DCS) aqueous leaf extract on laboratory-induced ulcers. Aqueous leaf extract prepared by maceration was orally administered one hour before ulcerogens in doses of 50, 100 and 200 mg/kg to groups of randomized adult rats of both sexes. Gastric ulcers were induced using pyloric ligation, methyleneblue, and acetic acid, while cysteamine, and indomethacin-histamine were separately employed for induction of duodenal ulcers in the animals. Positive controls were given standard drugs appropriate for each experimental model. Phytochemical screening of the freshly prepared extract was also carried out, as well as evaluating its antioxidant activity. In each of the models, the aqueous leaf extract of DCS showed a significant (p<0.05-0.001) dose-independent protection against peptic ulcer. The effects produced by the aqueous leaf extract of DCS were comparable to those of the standard drugs (omeprazole; 200 µg/kg, ranitidine; 50 mg/kg, and cimetidine; 50 mg/kg). Phytochemical analysis of the aqueous leaf extract of Daucuscarota sativus revealed the presence of flavonoids, tannins, alkaloids, and saponins, some of which have been reported to elicit cytoprotective effect. Antioxidant analysis showed significant scavenging effect of free radical using nitric oxide, lipid peroxidation and DPPH assay. The findings in this study suggest that the aqueous leaf extract of DCS possesses cytoprotective effect and also reduces secretion of secretagogues, thereby protecting against gastric and duodenal ulcers.

Proximate and phytochemical analyses of the root extracts of Justicia carnea and Justicia  secunda in the Acanthaceae family were investigated using standard procedures and compared. The result of the proximate analysis indicated that the roots of both species contain nutrients in varying levels. Protein (11.38±0.01), lipid (4.81±0.01) and moisture content (17.01±0.01) were higher in the roots of J. carnea than in J. secunda (8.32±0.01, 2.01±0.01, 11.22±0.02) respectively, while Carbohydrate (6.62±0.00), Ash (16.75±0.05) and Fibre (55.18±0.01) were higher in J. secunda than in J. carnea  (4.73±0.02, 9.81±0.01, and 52.29±0.00) respectively. Qualitative phytochemical analysis showed the presence of tannin, flavonoid, alkaloids, saponin, phytate and cyanogenic glycosides whereas the result for the quantitative analysis showed that the quantity of phytochemicals in Justicia carnea and Justicia secunda were: tannin (46.75±0.00 and 41.01±0.01), flavonoid (2.72±0.01 and 3.21±0.00), alkaloid (10.16±0.00 and 11.21±0.01), saponin (3.31±0.01 and 2.7±0.00), phytate (30.54±0.01 and 33.86±0.00) and cyanogenic glycoside (100.01±0.00 and 500±0.00) respectively. Justicia carnea contained higher quantity of tannin and saponin while Justicia secunda contained higher amount of flavonoid, alkanoid, phytate and cyanogenic glycoside. These results conceivably indicated that the two species are good sources of essential nutrients which could be used in diets to supplement the daily nutrient needs in humans and animals, and phyto-nutrients which possess strong pharmacological activities, providing scientific credence for its therapeutic usage in folklore medicine.
