The roots, stem-bark and leaves of Grewia mollis which is used as herbal remedies for the cure of diarrhea and dysentery by natives in northern part of Nigeria were studied. The ethanol and water extracts of roots, stem-bark and leaves of the plant were subjected to phytochemical screening and antimicrobial activity against Salmonella typhii, Escherichia coli, Streptococcus sp. and Staphylococc...

Stryphnodendron adstringens has a high tannin content and is used as an antiseptic and antimicrobial and in the treatment of leucorrhea, gonorrhea, wound healing, and gastritis. The present study evaluated the toxic effects of the heptamer prodelphinidin (F2) from the stem bark of S. adstringens in rodents. In the acute toxicity test, the mice that received oral doses exhibited reversible effec...

An ethanolic extract from the stem bark of Acacia oxyphylla, an indigenous anthelmintic plant among the Mizo tribes of north-east India, was tested in vitro to determine its anthelmintic activity on the fowl gastrointestinal cestode, Raillietina echinobothrida. The parasites were treated with varying concentrations, viz, 0.5, 1, 2, 5, 10, and 20 mg ml of the plant extract. On assessment of the ...

In view of alleged antidiabetic potential, effect of methanolic extract of Ficus carica L. (Moraceae) stem bark on fasting blood sugar levels and serum biochemical analysis in streptozotocin-induced diabetic rats were investigated. The resulted extract had shown significant protection and lowered the blood glucose levels to normal in glucose tolerance test. In long term treatment of streptozoto...

This study sought to investigate the ameliorative effects of ethanol extract Artocarpus heterophyllus (EAH) in alloxan-induced diabetic rats. The rats were divided into 6 groups, with groups 1 and 2 serving as nondiabetic and diabetic control, respectively; group 3 serving as diabetic rats treated with 5 mg/kg glibenclamide; and groups 4 to 6 were diabetic rats treated with 50, 100, and 150 mg/...

In deciduous trees, measurement of stem water potential can be difficult during the leafless period in winter. By using thermocouple psychrometry, osmotic water potentials (Ψo; actual Ψo: Ψo(act); Ψo at full saturation: Ψo(sat)) of expressed sap of bark and bud tissue were measured in order to test if the severity of winter desiccation in apple stems could be sufficiently assessed with Ψo. Wate...

In malarial endemic countries especially in the tropics, conventional antimalarial drugs are used with herbal remedies either concurrently or successively. Khaya grandifoliola is one of such popular herbs used in the treatment of malaria.Various doses of ethanol extract of K. grandifoliola stem bark (50-400 mg/kg/day) were administered orally to Swiss albino mice infected with Plasmodium yoelii...

Propionibacterium acnes and Staphylococcus epidermidis are the major skin bacteria that cause the formation of acne. The present study was conducted to investigate antibacterial activity of ethanolic extract of cinnamon bark, honey, and their combination against acne bacteria. The antibacterial activity of extract of cinnamon bark and honey were investigated against P. acnes and S. epidermidis ...

Traditionally, molecular studies of plant species have used leaves as the source of DNA. However, sampling leaves from tall tree species can be quite difficult and expensive. We developed a sequence of procedures for using stem bark as a source of DNA from Leguminosae trees of the Atlantic Forest and the Cerrado. Leguminosae is an important species-rich family in these two highly diverse and en...

The effects of the methanol extract of the stem bark of Prosopis africana (Guill., Perrott. and Rich.) Taubert (Fabaceae) on bleeding/clotting and coagulation time, excision and dead space wounds were studied in rats. Also, the extract was subjected to antibacterial, and acute toxicity and lethality (LD(50)) tests. The extract significantly (P<0.05) reduced bleeding/clotting and coagulation tim...
