Oral hygiene is important to the generality of the human healthcare system. For this, the antifungal activities of the aqueous and ethanol extracts of four medicinal plants of Jatropha curcas (stem), Eucaluptus golbulus (leaves), Vernonia amygdalina (stem) and Zanthoxylum zanthoxyloides (root) were carried out in vitro against three species of Candida associated with oral thrush namely C. albicans, C. glabrata, C. tropicalis using the disc diffusion agar assay. The zones of inhibition varied with the test organisms as well as the extracts. The ethanolic extract of Jatropha curcas showed the highest zone of inhibition of 10.88 ± 0.22 mm against C. albicans while the least zone of inhibition (6.13 ± 0.13 mm) was exhibited by the ethanol extract of Z. zanthoxyloides on C. glabrata. The preliminary phytochemical screening showed the presence of tannin, saponin, alkaloids, flavonoids and reducing sugar in all plant samples. This study can be further used as a foundation for the screening of phytochemical constituents by pharmaceuticals for the control and eradication of oral thrush.

The determination of the antibacterial activity (zone of inhibition) and minimum inhibitory concentration of medicinal plants a crucial step in drug development. In this study, the antibacterial activity and minimum inhibitory concentration of the ethanol extract of Myrsine africana were determined for Escherichia coli, Bacillus cereus, Staphylococcus epidermidis and Streptococcus pneumoniae. The zones of inhibition (mm±S.E) of 500mg/ml of M. africana ethanol extract were 22.00± 0.00 for E. coli,20.33 ±0.33 for B. cereus,25.00± 0.00 for S. epidermidis and 18. 17±0.17 for S. pneumoniae. The minimum inhibitory concentration(MIC) is the minimum dose required to inhibit growth a microorganism. Upon further double dilution of the 500mg/ml of M. africana extract, MIC was obtained for each organism. The MIC for E. coli, B. cereus, S. epidermidis and S. pneumoniae were 7.81mg/ml, 7.81mg/ml, 15.63mg/ml and 15.63mg/ml respectively. Crude extracts are considered active when they inhibit microorganisms with zones of inhibition of 8mm and above. Therefore, this study has shown that the ethanol extract of M. africana can control the growth of the four organisms tested.

The present work aimed to determine the phytochemical components and evaluate the in vitro anti-inflammatory and anti-mycobacterial effects of hydroethanolic extracts of Allium sativum L bulbs, Drypetes gossweileri S. MOORE stem-barks and Pentadiplandra brazzeana Baill roots against several resistant strains of Mycobacterium tuberculosis. The phytochemical screenings of extracts were carried out according the colorimetric and precipitation tests to reveal the presence of phytochemical compounds. The anti-inflammatory effects of extracts were evaluated using in vitro Bovine Serum Albumin denaturation and proteinase inhibitory action assays. The inhibitory parameters of hydro-ethanol extracts were evaluated by the microdilution method agaisnt Mycobacterium tuberculosis. The phytochemical screening of hydro-ethanol extracts revealed the presence of phenols, polyphenols, flavonoids, alkaloids, cathechic tannins, triterpens, steroids, anthocyanins and leucoanthocyanins. The anti-inflammatory activity of hydro-ethanol extracts of D. gossweileri, P. brazzeana and A. sativum have shown the inhibitory concentrations 50 (IC50) values ranging from 356.70, 183.30 and 226.30 mg/mL for BSA denaturation and 31.92, 33.62 and 56.93 mg/mL for proteinase inhibitory action respectively. The hydroethanolic extracts of D. gossweileri, P. brazzeana and A. sativum exhibited moderate and weak anti-mycobacterial activities with the minimum inhibitory concentrations (MICs) ranging from 312.5 to 2500 μg/mL. A. sativum hydro-ethanol extract has shown the highest anti-mycobacterial activity with MIC of 312.5 μg/mL against isoniazid resistant of M. tuberculosis and extremely resistant drug strain of M. tuberculosis. These results suggest that hydro-ethanol extracts of A. sativum, D. gossweileri and P. brazzeana are efficient against tuberculosis caused by multi-resistant Mycobacterium tuberculosis strains and are able to resorb the inflammation induced during infection.

A detailed investigation was performed with the aim to find out the indigenous medicinal plants having anthelminthic action. Ten (10) indigenous medicinal plants were primarily selected and the ethanol extracts were prepared for anthelminthic trial and determination of anthelminthic properties in vitro and in vivo against the gastro-instestinal nematodes in goat during the period from July 2006 to December 2006. Screening of ethanol extracts of selected plants showed the anthelmintic activity against gastrointestinal nematodes at lower concentration (50 mg/ml). In vivo screening (by oral administration) of four plant extracts (ethanol) showed variable degree of efficacy in experimentally infected goats, as measured by faecal egg count reduction test. A relatively higher efficacy was recorded in ethanol extract of neem treated animals in comparison to other plants extracts. Ethanol extracts of korolla also showed significant efficacy. The results obtained in this study showed that ethanol extract of Labanga, Neem, Karolla and Pineapple at the dose of 100mg/kg showed a significant and potent antinematodal effect. These findings indicate that the adult gastrointestinal nematodes are more vulnerable to selected indigenous plants. Within these ten (10) plants 4 showed more than 70% efficacy at a concentration of 100mg/mkg.

The whole plant of Vernonia mespilifolia is widely used as a traditional remedy for obesity in South Africa. The aim of this study was to investigate the anti-obesity and cytotoxic effects of Vernonia mespilifolia extracts in vitro. The α-amylase, α-glucosidase, and lipase inhibitory activities of aqueous and ethanol extracts of Vernonia mespilifolia were investigated, while the cytotoxic effects of these extracts were analyzed using Hoechst 33342 and propidium iodide (PI) dual staining on a human cervical HeLa cell line. The results showed that the LC50 (the concentration of a material will kill 50% of test organisms) values of aqueous and ethanol extracts of Vernonia mespilifolia were >200 and 149 µg/mL, respectively, to HeLa cells. Additionally, the ethanol extract exhibited the strongest inhibitory effect on the pancreatic lipase (Half-maximal inhibitory concentration (IC50) = 331.16 µg/mL) and on α-amylase (IC50 = 781.72 µg/mL), while the aqueous extract has the strongest α-glucosidase (IC50 = 450.88 µg/mL). Our results suggest that Vernonia mespilifolia’s acclaimed anti-obesity effects could be ascribed to its ability to inhibit both carbohydrate and fat digesting enzymes.

Background: A snake bite is fundamentally an injury often resulting in puncture wounds meted out by the animal's fangs and occasionally resulting in envenomation. Rate of snake bites around 5,400,000 bites per year leads to over 2,500,000 envenomings and around 125,000 fatal cases annually. Snake venom enzymes are rich in metalloproteinases, phospholipaseA2, proteinases, acetylcholinesterases and hyaluronidases. Objective: Cyphostemma adenocoule is traditionally being used for the treatment of snake bites in Eritrea. The present research was aimed at evaluating the snake venom enzyme inhibition activity of C. adenocoule against puff adder venom and developing a base for the traditional use of the plant against snakebites in Eritrea. Methods: The anti-venom activity of C. adenocoule was assessed in-vitro through phospholipaseA2 enzyme inhibition assay using egg yolk as a cell. The ethanol and chloroform extracts of C. adenocoule showed in vitro anti phospholipase A2 activity, whereas the water extracts of the plant showed no activity. Results: Among the extracts of C. adenocoule, the highest percentage of inhibition was obtained from chloroform extract (95.55% at 100mg/ml). The extract showed prominent activity at different concentrations (34.7% at10mg/ml, 48.8% at 20mg/ml, 54.8% at 40mg/ml, 60.9% at 60mg/ml, 80.5% at 80mg /ml). The ethanol extract also showed certain activity at various concentrations (25.22% at10mg/ml, 14.78% at 20mg/ml, 2.6% at40mg/ml). The activity of the chloroform extracts increases as concentration increases, whereas the activity of the ethanol extracts decreases as concentration increases. The aqueous extract of C. adenocoule did not show any activity at all concentrations. Conclusion: In this study, the chloroform and ethanol extracts of the plant inhibited the enzyme of interest and thus proved the efficacy of anti-snake venom activity of the plant.
