Objective: To investigate the effect of ethanol extracts from Dioscoreae Nipponicae Rhizoma on hyperuricemic mice.
Methods: The hyperuricemia was induced by gavage of hypoxanthine and subcutaneous injection of potassium oxonate (model A) or subcutaneous injection of uric acid (model B) in ICR male mice. The mice in ethanol extracts groups were administrated with Dioscoreae Nipponicae Rhizoma ethanol extracts 5.4 g/kg by gavage, the positive control groups were given with 10 mg/ml allopurinol or 5 mg/ml benzbromarone by gavage, respectively. The plasma uric acid levels were measured by using HPLC.
Results: The plasma uric acid levels of model group, control group and ethanol extract group in model A mice were (40.03±27.24), (4.08±1.47) and (18.10±8.87) g/mL (compared with model group, P <0.05), respectively. The plasma uric acid levels of model group, control group and ethanol extract group in model B mice were (18.57±3.83), (4.29±2.36) and (15.36±2.71) g/mL (compared with model group, P <0.05), respectively.
Conclusion: The ethanol extracts from Dioscoreae Nipponicae Rhizoma have certain hypouricemic effect in hyperuricemic mice induced by hypoxanthine and potassium oxonate or by uric acid.

The mushroom Pleurotus ostreatus is widely produced in Brazil and its stipes are discarded before commercialization. In the present study, this agricultural fungal waste (mushroom stipes), was analyzed by preparing an aqueous extract and obtaining the polysaccharides by ethanol precipitation (POS-extract). The fraction presented 37 % of carbohydrates and small amounts of proteins and phenolic compounds.

Direct thrombin inhibitors (designated as EuRL-DTIs) were partially purified from ethanol extracts of Euphorbia resinifera O.Berg latex. The obtained EuRL-DTIs comprised four major compounds: two isomers of phenolic compounds (CHO) and two amide compounds (tentatively identified as CHNO and CHNO), as identified by liquid chromatography and electrospray ionisation quadrupole time-of-flight mass spectrometry (LC-ESI-QTOF-MS/MS), attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectroscopy, and/or nuclear magnetic resonance (NMR) spectroscopy.

The antioxidant extracts considered a very important food additive which promoting the protection of lipid and prolong the shelf life of food products. The aim of this investigation was decrease the time of extraction of hibiscus leaves extract (HLE) and olive leaves extract (OLE) from 48 h to only 6 h without reducing efficiency of these extracts. HPLC assay, scavenging radical activity by DPPH˙ (IC), inhibition lipid peroxidation by both β-Carotene/Linoleic Acid Bleaching (βCB) and Thiobarbituric Acid Reactive Substances (TBARs) assays, antibacterial and antifungal activities measured for different concentrations of ethanolic extracts by conventional extraction (CE) and difference in pressure extraction (DPE) methods, and the results shown a considerable in mean difference ( < 0.
