1 It is found in wooded areas of Senegal, southern part of Nigeria, Central and Eastern Africa. 2 It is used for the treatment of backache, diabetes and as an anti-scorbutic. The leaves of the plant boiled in its own sap are used for the treatment of gastrointestinal sores. 1 Its sap is used for toothache and cough. 3 It is used in the treatment of jaundice and haemorrhoids among the Baka Pygmies of Cameroon and also used in the traditional

treatment of inflammatory, skin infection and ulcer. 4 and 5 The presence of alkaloids, tannins, saponins, phlobatannins, terpenoids and flavonoids in the leaves of T. inhibitors potatoria has been reported. 6T. potatoria root has also been found to contain phytochemicals such as tannins, flavonoids, phlobatannins and cardiac glycosides. 7 Betulinic acid, 3β-hydroxy-lup-20(29)-en-28-oic acid, a C-28 carboxylic acid derivative of the ubiquitous triterpene SB203580 clinical trial betulin, is a member of the class of the lupane-type pentacyclic triterpenes.

selleck screening library betulinic acid possesses a number of intriguing pharmacological effects including: anti-inflammatory, anticancer and anti-HIV.5, 9 and 10 T. potatoria root was collected from Ilesa, Osun state, Nigeria and authenticated by Mr. G. Ibhanesebhor, plant taxonomist, Herbarium, Obafemi Awolowo University, Ile-Ife, Nigeria. Voucher specimen (IFE Herbarium 16419) was deposited in the herbarium. The plant material Mephenoxalone was air-dried, pulverised

and extracted by soaking 1.2 kg sample in aspirator bottles containing distilled methanol at room temperature (25 °C) for 48 h. The extract was filtered and solvent was completely removed by vacuum evaporator at 50 °C to give viscous mass (18.55 g, 1.5% yield), which was stored inside a dessicator for further usage. Phytochemical screenings of MeTp were performed using standard procedures.11, 12 and 13 0.5 g of the extract was boiled with 10 ml of sulphuric acid (H2SO4) and filtered hot. The filtrate was shaken with 5 ml of chloroform. The chloroform layer was pipetted into another test tube and 1 ml of dilute ammonia solution was added. The presence of pink colour in the aqueous layer indicated the presence of anthraquinones. 5 ml dilute ammonia was added to a portion of an aqueous filtrate of the extract. Concentrated sulphuric acid (1 ml) was added. A yellow colouration that disappears on standing indicates the presence of flavonoids. About 0.5 g of the extract was boiled in 10 ml of water in a test tube and then filtered. A few drops of 0.1% ferric chloride was added and observed for brownish green or a blue-black colouration. To 0.5 g of extract was added 5 ml of distilled water in a test tube. The solution was shaken vigorously and observed for a stable persistent froth.
