UNLABELLED The red seaweed Phyllophora pseudoceranoides (Gmelin) New. et Tayl, commonly found in the Romanian Black Sea coastal waters, has not been studied regarding its chemical composition and biological activities. AIMS The aim of the present study was to isolate, characterize and assess the in vitro antioxidant activity of the crude polysaccharide from P. pseudocerano ides. MATERIALS A...

Lamiaceae herbs known for their culinary properties are a rich source of potentially health-beneficial antioxidant polyphenols. The objective of this investigation was to evaluate and prove the in vitro antioxidant activity of five different extracts of aerial parts of the plant Leucas aspera, belonging to the family Lamiaceae on different models namely the DPPH free radical scavenging assay, F...

Polyphenols and flavonoids possess a variety of biological activities including antioxidant and anti-tumor activities. Ixora parviflora is a member of the flavonoid-rich Rubiaceae family of flowering plants and used as folk medicine in India. The aim of this study was to investigate the antioxidant activity of Ixora parviflora extract (IPE) in a cell-free system and erythrocytes, and the abilit...

Four seaweed polysaccharides were extracted from Sarcodia ceylonensis, Ulva lactuca L., Gracilaria lemaneiformis, and Durvillaea antarctica, respectively, by microwave-assisted extraction. The effect of three significant variables (extraction time, extraction temperature, and the ratio of water to raw material) on the process for extracting polysaccharides was investigated, along with the optim...

BACKGROUND This study investigated the hepatoprotective effect and antioxidant properties of phloroacetophenone (2',4',6'-trihydroxyacetophenone - THA), an acetophenone derived from the plant Myrcia multiflora. MATERIAL #ENTITYSTARTX00026; METHOD The free radical scavenging activity in vitro and induction of oxidative hepatic damage by carbon tetrachloride (CCl(4)) (0.5 ml/kg, i.p.) were test...

BACKGROUND Myrtle (Myrtus communis L.) is a medicinal and aromatic plant belonging to Myrtaceae family, which is largely diffused in the Mediterranean areas and mainly cultivated in Tunisia and Italy. To the best of our knowledge, no studies have already considered the use of the lactic acid fermentation to enhance the functional features of M. communis. This study aimed at using a selected lac...

Houttuynia cordata Thunb (Saururaceae) is a traditional medicinal herb used to treat several disease symptoms. The present study was focused on the hepatoprotective effects of H. cordata ethyl acetate extract in experimental mice. Further the antioxidant potential of the extract was also evaluated to substantiate its hepatoprotective properties. Carbon tetrachloride-induced hepatic damage in mi...

BACKGROUND Production of reactive oxygen species is a common cause in alcohol induced liver diseases. Decoction prepared from the whole plant of Eriocaulon quinquingulare is prescribed to treat liver disorders. The aim of this study was to investigate the hepatoprotective activity and antioxidant capacity of the water extract of E. quinquangulare in vitro. METHOD The aqueous extract of the wh...

BACKGROUND Flueggea leucopyrus Willd is a shrub grown in many parts of the dry zones in Sri Lanka. The leaves of F. leucopyrus has been used for treating cancer in the traditional system of medicine in Sri Lanka. Hence, this study was performed to analyze the antioxidant and antiproliferative properties of the aqueous extract of the leaves of F. leucopyrus on HEp-2 cells. METHOD The aqueous e...

The effects of different cooking methods on total bioactive compound content were determined, and in vitro antioxidant activity in 80% ethanolic extracts of Brussels sprouts was evaluated by spectrophotometric methods. Compared to uncooked, steamed, and microwaved Brussels sprouts extracted with 80% ethanol contained higher amounts of total polyphenols. Uncooked Brussels sprouts contained the h...
