Prospects of botanical pesticides from neem, Azadirachta indica for routine protection of cocoa farms against the brown cocoa mirid – Sahlbergella singularis in Nigeria
The brown cocoa mirids, Sahlbergella singularis (Haglund) is the most damaging insect pest of cocoa in Nigeria. The principal means of mirid control has been, for many years, the application of synthetic insecticides on the basis of calendar spray schedule. The use of synthetic pesticides on small-scale farms in the tropics is generally not advocated because the approach lacks sustainability and raises...

In vitro modulation of tracheal smooth muscle reactivity by extracts of some Senegalese medicinal plants
Scientific validation of pharmacological actions of 7 Senegalese plants used in traditional medicine for the treatment of respiratory illness was carried out. Changes in contractility of isolated rat trachea were assessed in organ chambers. Rings were allowed to equilibrate for 60 min before experiments were carried out, during which time the resting tension was adjusted, as required. Rings were first exposed to...

Antihyperglycemic activity of polysaccharide from Lycium barbarum
A study was undertaken to evaluate antihyperglycemic activity of polysaccharide from Lycium barbarum (LBP). The various parameters studied included body weight, fasting blood glucose levels, total cholesterol (TC) and triglyceride (TG) in diabetic and normal mice. LBP treatment (20, 40 mg/ kg body weight) for 28days resulted in a significant decrease in the concentration of fasting...

Phytochemicals, antioxidant properties and anticancer investigations of the different parts of several gingers species (Boesenbergia rotunda, Boesenbergia pulchella var attenuata and Boesenbergia armeniaca)
Extracts (methanol) of the leaves, stem and rhizome of Boesenbergia specieswere studied for their phytochemical constituents, total phenolics and flavonoid contents, antioxidant as well as anticancer properties. The plants revealed the presence of polyphenols such as quercetin, kaempferol, rutin, naringin, hesperidin, caffeic acid, p-coumaric acid, ferulic acid, sinapic acid, chlorogenic acid, gallic acid,...

Effects of fertilizer on yield, essential oil composition, total phenolic content and antioxidant activity in Satureja hortensis L. (Lamiaceae) cultivated in Iran
The effects of different amounts of compelet fertilizer on the yield, fresh and dry weight, essential oil composition, total phenolic content and antioxidant activity ofSatureja hortensis L. was investigated. Different amounts of compelet fertilizer (0, 500, 1000 and 1500 mg/plant) were applied. The results showed that the use of fertilizer increases fresh and dry weigh in S. hortensis. One thousand and...

An aqueous extract of Citrus mitis possesses antioxidative properties and improves plasma lipid profiles in rat induced with high cholesterol diet
The in vitro antioxidant activity of Citrus mitis aqueous extract (CME) and its effects on antioxidative status and lipid profiles of rat fed with high cholesterol diet were examined. The in vitro antioxidant activity was assessed by 1,1-diphenyl-2-picrylhydrazyl (DPPH) and ferric-reducing antioxidant power (FRAP), while the total phenolic content was measured as gallic acid...

Antimicrobial activity, cytotoxicity and phytochemical screening of Ficus septica Burm and Sterculia foetida L. leaf extracts
Ethanol extracts of leaves of Ficus septica Burm and Sterculia foetida L. were examined for their antibacterial, antifungal, antiprotozoal, and cytotoxic properties. To determine these activities, the extracts were tested against bacteria and fungus through disc diffusion assay; against protozoa through growth curve determination, antiprotozoal and cytotoxicity assays. The extracts revealed...
