Over 25% of our common medicines contain at least some compounds obtained from plants. Nupeland located on the coastal basins of Rivers Niger and Kaduna in North Central Nigeria is greatly influenced by the savannah-forest vegetations with biodiversity rich in medicinal plants. This type of vegetation also harbours tsetsefly which are the vector of trypanosomes, thus making the area highly ende...

Objective: To evaluate the hepatoprotective activity of crude aqueous and ethanol stem bark extracts of Pterocarpus santalinus (Fabaceae) using CCl 4 induced hepatic damage in male Wistar albino rats. Department of Botany, Materials and Methods: The aqueous (45 mg/ml) and ethanol (30 mg/ml) extracts of S.R.N.M.N. College of Applied stem bark in 1% gum tragacanth was administered orally for 14 d...

This paper describes the antioxidant and antimicrobial activities and phenolic components of different solvent (absolute methanol, absolute ethanol, absolute acetone, 80% methanol, 80% ethanol, 80% acetone and deionized water) extracts of leaves, flowers and bark of Gold Mohar [Delonix regia (Bojer ex Hook.) Raf.]. The extract yields from leaves, flowers and bark ranged from 10.19 to 36.24, 12....

Natural compounds from certain timber trees are highly valued and recommended to protect wood and wood products against mold fungi. This study highlighted the use of some natural extracts and Paraloid B72 against the growth of two mold fungi, namely Alternaria tenuissima and Fusarium culmorum. From the in vitro experiment, the methanol extracts of Callistemon viminalis bark were effective again...

BACKGROUND Aging is an inevitable process for all living organisms. During this process reactive oxygen species generation is increased which leads to the activation of hyaluronidase, collagenase and elastase, which can further contribute to skin aging. Four southern African medicinal plants; Clerodendrum glabrum, Schotia brachypetala, Psychotria capensis and Peltophorum africanum, were investi...

The hypoglycemic effects of water and butanolic extracts prepared from the bark of Acosmium panamense (Fabaceae) were studied in diabetic rats (streptozotocin (STZ)-induced). Oral application of water extracts at doses of 20 and 200 mg/kg and of butanol extracts at doses of 20 and 100 mg/kg significantly lowered the plasma glucose levels in diabetic rats within 3 h. Glibenclamide was used as re...

BACKGROUND Pleurostylia capensis is a large tree that can reach the maximum height of 20 m long, and it have been traditionally used as cosmetic, for steam bath, ritual body wash, and as a purgative to treat symptoms of witchcraft. Using ethanol, chloroform, dichloromethane (DCM), ethyl acetate (EA), and water extracts, leaves, bark and roots of Pleurostylia capensis were investigated scientifi...

BACKGROUND The paste of stem bark of Azadirachta indica (AI) has been traditionally used on wound and scar for rapid healing in Bundelkhand region of India. OBJECTIVE In the present investigation, wound healing potential of different extracts of stem bark of AI was explored in mice model. MATERIALS AND METHODS To study the wound healing properties in small animal model, the excision and inc...

BACKGROUND In the present study, the methanol extracts from the leaves, as well as compounds namely sigmoidin I (1), atalantoflavone (2), bidwillon A (3), neocyclomorusin (4), 6α-hydroxyphaseollidin (5) and neobavaisoflavone (6) (from the bark extract) were tested for their activities against a panel of Gram-negative bacteria including multi-drug resistant (MDR) phenotypes. METHODS Broth micr...

Kola nut is chewed in many West African cultures and is used ceremonially. The aim of this study is to investigate some biological effects of Cola nitida's bark after phytochemical screening. The bark was collected, dried, and then powdered for the phytochemical screening and extractions. Ethanol and ethyl acetate extracts of C. nitida were used in this study. The antibacterial activity was tes...
