Opis:
The phytochemical properties of the ethanolic leaves extract of Tetracarpidium conophorum and its antidiabetic properties on alloxan-induced diabetic albino rats were evaluated. The qualitative phytochemical screening revealed the presence of alkaloids, tannins, saponins, terpenes, flavonoids, cardiac glycosides and anthraquinones in T. conophorum leaf extract. Quantitative phytochemical screening of T. conophorum revealed the presence of saponins (8.77 ± 1.15 mg/kg), tannins (7.84 ± 0.62 mg/kg), alkaloids (5.49 ± 0.14 mg/kg), flavonoids (5.26 ± 0.16 mg/kg), cardiac glycosides (2.13 ± 0.45 mg/kg), terpenes (1.47 ± 0.30 mg/kg) and anthraquinones (1.33 ± 0.18 mg/kg). The toxicity test of the extracts produced various degree of toxicity ranging from writhing, decreased respiration, convulsion to mortality. The intensities of these effects were proportional to the dose administered. The LD50 for T. conophorum was 1369.31 mg/kg. The results of the influence of ethanolic leaves of T. conophorum on alloxan-induced diabetic rats showed significant (p<0.05) reduction in the blood glucose level (BGL) as time of treatments increases. The leaves extracts of T. conophorum significantly (p<0.05) decreased the blood glucose level of diabetic rats on day 14 compared to diabetic untreated (control) rats. The BGL of diabetic rats treated with oral hypoglycemic agent alone were significantly (p<0.05) different from control group on day 14. The presence of these biologically active compounds suggest that the plant could serve as potential sources of drugs and their secondary metabolites could exert some biological activities when taken by animals. The extracts of T. conophorum also produced a similar reduction in blood sugar level as the standard hypoglycemic drug (Glibenclamide). This may be due to its ability to enhance insulin secretion like the standard drug. This positive result confirms why herbalists use this leaf for the management of diabetes.

Opis:
Phytochemicals, proximate, minerals and anti-nutrient compositions of young cocoyam (Colocasia esculenta) leaves were determined using standard methods. Qualitative and quantitative analyses for phytochemicals confirmed the presence of bioactive constituents such as alkaloids, flavonoids and saponins in appreciable amounts, while terpenes, cardiac glycocides and tannins were only present in trace concentrations. Mineral analysis revealed that K recorded the highest content - with 214.00 ± 2.11 mg/100g, followed by Ca - 157.10 ± 1.47 mg/100g, Mg - 63.00 ± 0.58 mg/100g, P - 32.00 ± 0.61 mg/100g, while Fe had the lowest value - 0.10 ± 0.14 mg/100g. Proximate composition analysis of C. esculenta leaves indicated that CHO, protein and crude fibre were present in high quantities (35.22, 17.10 and 16.41 % respectively), while fat was at the lowest content (8.82%). Anti-nutritional factor analysis of young leaves of C. esculenta indicated that phytates was present in huge quantity - 11.03 ± 0.12mg/g, followed by oxalates - 7.62 ± 0.14 mg/g, while tannins recorded the lowest anti-nutritional contents - 0.12 ± 0.06 mg/g. This study has also revealed that the young leaves of C. esculenta contain appreciable levels of bioactive components (phytochemicals such as as alkaloids, flavonoids and saponins; minerals K, Ca, Mg, P and Fe) and appreciable amounts of CHO, protein and crude fibre. The results of anti-nutrients analysis showed high contents of phytate and oxalate. The last is probably responsible for the itching effect and also interferes with the utilization of essential nutrients. Thus, young leaves of C. esculenta provide appreciable quantities of nutrients and thus can rival other conventional vegetables normally consumed in Nigeria.
