Arfan M., Amin H., Karamać M., Kosińska A., Wiczkowski W., Amarowicz R. (2009): Antioxidant activity of phenolic fractions of Mallotus philippinensis bark extract. Czech J. Food Sci., 27: 109–117. Phenolic compounds were extracted from Mallotus philippinensis bark using methanol. Six fractions (I–VI) were separated from the extract on a Sephadex LH-20 column using ethanol and acetone-water as t...

Agrimony (Agrimonia eupatoria L.) (Ae) is used in traditional medicine to treat inflammatory and oxidative related diseases. Therefore, this study focuses on the anti-inflammatory and analgesic potential of Ae infusion (AeI). Phenolic compounds characterization was achieved by HPLC-PDA-ESI/MS n . To evaluate antioxidant potential, 2,2-diphenyl-1-picrylhydrazyl (DPPH), superoxide anion, hydroxyl...

Background: The aromatic plant Stachys mucronata (Lamiaceae) is endemic to the island of Crete (southern Greece), but as opposed to other native Greek members of this family, this species has never been investigated in the past with regard to its polyphenolic composition and antioxidant potency. Methods: Aerial parts of S. mucronata were exhaustively extracted and partly fractionated through pa...

Red fruit (Pandanus conoideus Lam) is one of the fruits commonly consumed as diet by societies, especially in Papua, Indonesia. Preliminary research revealed that among three extracts of red fruit evaluated, ethyl acetate extract had the highest antiradical activities; therefore, this research was directed to fractionate ethyl acetate extract, evaluate antioxidant activities using in vitro meth...

INTRODUCTION Because of its chemical diversity, the only way to standardise propolis is to specify multiple standards for different propolis types according to the corresponding chemical profile. So far, this has been done only for European propolis. OBJECTIVE To develop a rapid low-cost spectrophotometric procedure for quantification of bioactive prenylated flavanones in Taiwanese propolis. ...

Thrombosis and stroke are major causes of disability and death worldwide. However, the regular antithrombotic drugs may have unsatisfactory results and side effects. Platonin, a cyanine photosensitizing dye, has been used to treat trauma, ulcers and some acute inflammation. Here, we explored the neuroprotective effects of platonin against middle cerebral artery occlusion (MCAO)-induced ischemic...

Phenolic compounds have been shown to exhibit bioactive properties, and in particular antioxidant effects. A phenolic-rich fraction has been isolated from the aqueous by-product obtained during the milling of oil palm fruits. The objectives of the study were to determine the phenolic content of the crude and ethanolic extracts of oil palm fruits and to evaluate the antioxidant properties of the...

Background: Thermal waters have been showing different beneficial effects on the skin due to their physicochemical composition. The effect of thermal water in treatment some diseases may thus justify its use as an active ingredient cosmetic formulations. main objective this work was demonstrate potential incorporating (2) Methods: A descriptive literature review carried out by analysis scientif...
