Effect of ethanol leaf extract of Gnetum africanum on testosterone and oestradiol induced benign prostatic hyperplasia
The effect of ethanol leaf extract of Gnetum africanum was studied in albino rats induced with benign prostatic hyperplasia. The animals (36) were randomly grouped into six with six rats in each group. Testosterone and oestradiol every other day for 28 days was used to induce hyperplasia. The test groups (2 - 4) were treated with 200, 400 and 800 mg/kg body weight of extract for another 28 days. Group 5 was given the...

Separation and identification of phenolics and flavonoids from wild Pistacia palaestina extract and its antioxidant activity
An in-vitro evaluation of the antioxidant activities of wild Palestinian Pistacia palaestina extracts was done. In parallel, the total phenolic content (TPC) and the total flavonoids content (TFC) were measured. The antioxidant activities were determined spectrophotometrically by DPPH, FRAP, CUPRAC and the ABTS methods. The phenolic and flavonoid contents were separated and identified using LC-PDA-MS. The P. palaestina...
