Aims: The current investigation aimed to assess the antioxidant, antidiabetic and antilipidemic effects of the aqueous extract of aerial part of Cotula cinerea (C. cinerea). Background: Cotula cinerea (Del). which belongs to the Asteraceae family is commonly used traditionally for the treatment of diabetes. Objective: The objective of the study was to study the effect of the aqueous C. cinerea extract on glucose and lipid metabolism in normal and streptozotocin-induced diabetic rats using a single and repeated oral administration. Methods: A preliminary phytochemical screening and the quantification of phenolic and flavonoid contents as well as the antioxidant activity using three methods (DPPH, FRAP and ABTS) were carried out. The effect of a single and repeated (15 days of treatment) oral administration of the aqueous extract of aerial part of Cotula cinerea (AEAPCC) at a dose of 20 mg/kg on glucose and lipid profile was examined in normal and streptozotocin-induced diabetic rats. Additionally, histopathological examination of the pancreas and liver was carried out according to the Hematoxylin-Eosin method. Results: AEAPCC (20 mg/kg) showed a significant blood glucose-lowering activity in both normal and diabetic rats after a single and repeated oral administration during 15 days. The aqueous extract was also able to decrease the plasma triglycerides levels in both normal and diabetic rats after 15 days of oral treatment at a dose of 20 mg/Kg while no effect was observed on plasma cholesterol levels. In addition, the results show that AEAPCC exhibits an in vitro antioxidant activity using different tests. Histopathological analysis of the pancreas and liver of AEAPCC-treated diabetic rats has revealed that AEAPCC had a beneficial effect on the architecture of these organs while no improvement of glucose tolerance was noticed using the glucose tolerance test. Furthermore, the results showed that the extract is rich in several phytochemical compounds and exhibited an important antioxidant activity. The phytochemical screening revealed that AEAPCC contains polyphenolic compounds, flavonoids, tannins, alkaloids, saponins, quinones, sterols, terpenoids, anthroquinones and reducing sugars. Whereas, it is free from glycosides. Conclusion: In conclusion, this study demonstrates that Cotula cinerea possesses a beneficial effect on diabetes. Further investigations are required to study the mechanism of action of the antidiabetic effect of this plant.

The search for antimalarial compounds has been necessitated by the resistance of Plasmodium falciparum to almost all antimalarial drugs. The aim of this research was to determine in-vitro antimalarial activity of extracts of some indigenous plants species in Kebbi State. Plant extraction was carried-out by maceration using ethanol and water as solvent. The antiplasmodial activity of the extracts was evaluated against fresh clinical isolates of P. falciparum using WHO method of in-vitro micro test. Phytochemical screening was also carried out on the extract to deduce the active chemicals present in the plant extract. All plant extracts demonstrate dose dependent antimicrobial activities with IC50 Less than 50%. However highest growth inhibition of the P. falciparum was demonstrated by aqueous and ethanol extract of A. indica with IC50 7.4µg/ml and 8.6µg/ml respectively followed by ethanol and aqueous extract of C. occidentalis with IC50 15.3µg/ml and 18.0µg/ml respectively. Least antimalarial activity was demonstrated by aqueous extract of M. oleifera with IC50 33.5µg/ml while ethanolic extract of M. oleifera demonstrated IC50 of 20.50µg/ml. M. indica ethanolic and aqueous extract also demonstrated moderate antimalarial activity with IC50 18.8µg/ml and 24.5µg/ml. The phytochemical screening of medicinal plants showed the presence of tannins, saponins, alkaloids, flavonoid, phenol and cardiac glycosides in the extracts, which may be responsible for the antiplasmodial activity. This result justifies the traditional use of the plant in malaria treatment and further research is suggested to identify and characterize the active principles from the plants.

Olea europaea var. sylvestris, also named oleaster, is widely used by traditional medicine practitioners in Algeria to treat high blood pressure and diabetes. However, the antidiarrhoeal activity of this plant has not been scientifically evaluated. The main aim of the study deals with an investigation of three topics: the phytochemical screening, the acute toxicity, and antidiarrhoeal activity of the oleaster leaf aqueous extract. Acute oral toxicity study was carried out based on Organization for Economic Cooperation and Development 423 guideline. The extract was orally administered in wistar rats at a single dose of 2000 mg/kg body weight and the animals were observed for mortality, behavioral changes and other abnormal signs. Qualitative analysis of phytochemical constituents was carried out using standard methods developed by Harborne, Trease and Evans. Castor oil-induced diarrhoea tests and gastro intestinal motility assay were evaluated in rats to determine the antidiarrhoeal activity of the extract. In the acute toxicity study, the extract did not induce death or any sign of toxicity in treated rats. The preliminary phytochemical screening of the extract revealed the presence of saponins, flavonoids, and triterpenoids. The oleaster extract at oral doses of 100, 200 and 400 mg/kg body weight showed a significant (P<0.05) antidiarrhoeal activity compared to the control group treated with castor oil induced diarrhoea, enteropooling and gastrointestinal motility assay, after charcoal meal administration. The oleaster leaf aqueous extract has shown a gradual response with increasing dose. The present study indicates that the oleaster leaf aqueous extract is safe with antidiarrhoeal property.

Asparagus racemosus Willd. is an important medicinal plant of tropical and subtropical regions of Nepal and India. Its medicinal usage has been reported in the Indian and British Pharmacopoeias and in traditional systems of medicine such as Ayurveda, Unani, and Siddha. Asparagus curillus Buch-Ham.ex Roxb. is also one of the species found in higher altitude of Nepal. Its roots are used as substitute for A. racemosus. Phytochemical investigation was done for these two species of Nepalese Asparagus as per Methodology for Analysis of Vegetable Drugs by I. Ciulei.1982. Phytochemical screening revealed the presence of coumarin, flavonoid, catecholic tannin, reducing compound in alcoholic extract of A. racemosus while its aqueous extract revealed polyuronoid, reducing compound, polyoses, saponin, gallic tannin, catecholic tannin, etc. Similarly, alcoholic extract of A. curillus revealed catecholic tannin, reducing compound and aqueous extract revealed polyuronoid polyoses, saponin, gallic tannin as main phytochemical compounds. Comparative antimicrobial activity of ethanolic extract of these two species has been evaluated using Kirby-Bauer Agar well diffusion method. The extracts were screened for their antimicrobial activity on nine different strains of human pathogenic microorganisms such as Escherichia coli, Salmonella typhi, Bacillus subtilis, Pseudomonas aeruginosa, Staphylococcus aureus, Klebsiella pneumoniae, Enterococcus faecalies, Saccharomyces cerevisiae and Candida albicans. Among them A. racemosus has shown selected antimicrobial effects against B. subtilis, E. coli, E. faecalis, S. cerevisiae and C. albicans with zone of inhibition of 25 mm in an average. While A. curillus showed effects on S. cerevisiae and C. albicans only with zone of inhibition about12 mm.J. Nat. Hist. Mus. Vol. 29, 2015, Page: 91-102

Aims: Treatment against schistosomiasis relies on praziquantel. Its treatment failure and the possible development of resistant schistosomes strains have been reported in the literature. Clerodendrum umbellatum leaves are used in Africa for the treatment of intestinal helminthiasis. The aim of this study was to evaluate the in vitro activity of C. umbellatum leaves aqueous extract and derived fractions on Schistosoma mansoni adult worms. Methodology: Five male and five female Schistosoma mansoni adult worms were incubated in each well for 48 h in a GMEM culture medium with C. umbellatum aqueous extract (125 to 4000 µg/mL) or its n-hexane, ethyl acetate and methanol fractions or the aqueous residue (62.5 to 2000 µg/mL). The main parameters assessed were the worm’s mortality and the reduction of motor activity. Phytochemical screening of all our tested substances was also performed. The cytotoxicity assay using mouse melanoma liver cells line was performed on the aqueous extract and on the most active fraction. Results: Our study shown that C. umbellatum leaves aqueous extract and its derived fractions promoted worm mortality. The aqueous extract disclosed a LC50 of 805.21 µg/mL while the LC50 of the methanol fraction was 343.10 µg/mL. With this lowest LC50, the methanol fraction from C. umbellatum aqueous extract was therefore the most active. Moreover, it showed low level of toxicity on hepatocytes. Incubation of worms with C. umbellatum aqueous extract and fractions also resulted in a significant reduction of the motor activity of survival worms with a 39.54 to 100% reduction after 48h. The phytochemical screening of C. umbellatum aqueous extract and fractions revealed the presence of alkaloids, phenols, flavonoids, tannins, saponins and terpenoids. Conclusion: The present study demonstrated the in vitro activity of C. umbellatum aqueous extract and derived fractions on S. mansoni adult worms and could then justify its empirical use to combat schistosomiasis.
