- Abstract:
- ... Phenolic and flavonoid contents in leaf extracts of Bergenia ligulata have been analysed for their contribution in antimicrobial and antioxidant activities. The extracts were prepared in three solvents (separately) following maceration and soxhelt methods. The antimicrobial activity was tested using disc diffusion assay against a range of microorganisms along with the determination of minimum inhi ...

- Abstract:
- ... BACKGROUND: The National Health and Morbidity Survey in 2011 estimated that 35.1% (5.7 million) of Malaysian adults aged 18 and older suffer from hypertension. Hypertension is still treated by conventional medicine despite its exact aetiology being unknown. Studies showed that oxidative stress and low availability of nitric oxide (NO) causes an increase in vascular wall tension and increase blood ...

- Abstract:
- ... Individual phenolic compounds, total phenolic content and antioxidant potential were assessed in kernels, oils and bagasse pellets (residues of oil pressing) of different walnut cultivars. Twenty-seven phenolic compounds were detected in kernels and pellets conducting high-performance liquid chromatography–tandem mass spectrometry. The main polyphenolic subclass comprised hydrolysable tannins, whi ...

- Abstract:
- ... Seven antioxidant capacity assays were compared and evaluated (ranked and grouped) using several statistical methods. The aim of the research was to compare the results of different antioxidant capacity assays and choose preferably one (or two) method(s), which could reproduce on its own the consensus results of all of the others. The two datasets (berries and sour cherries) gave quite similar res ...

- Abstract:
- ... Tinctures are almost the oldest medicines and their use is substantial in the medication nowadays as well. The antioxidant values by ferric reducing/antioxidant power (FRAP) method and element content by inductively coupled plasma optical emission spectrometry (ICP-OES) were investigated in some tinctures official in the VII. and VIII. Pharmacopoeia Hungarica. The highest FRAP values were found fo ...

- Abstract:
- ... Clinical efficacy of the widely used anticancer drug cisplatin is limited due to its adverse side effects in normal tissues mediated by oxidative stress. This study was aimed to investigate the protective effects of vetiver acetate oil, Java (VO) against cisplatin-induced toxicity in Swiss albino mice. The ameliorating potential was evaluated by orally priming the animals with VO at doses 5, 10 or ...

- Abstract:
- ... Carotenoids are natural pigments that act as powerful antioxidants and have various beneficial effects on human and animal health. Mucor circinelloides (Mucoromycotina) is a carotenoid producing zygomycetes fungus, which accumulates β-carotene as the main carotenoid but also able to produce the hydroxylated derivatives of β-carotene (i.e. zeaxanthin and β-cryptoxanthin) in low amount. These xantho ...

Partially purified polysaccharides (FP) and hot alkali extract (FNa) obtained from fruiting bodies of the wild basidiomycete Grifola frondosa were examined for their antimicrobial, antioxidant and cytotoxic activity. The structural properties of FP and FNa samples were investigated by FT-IR and high resolution 1H- and 13C-NMR spectroscopy. From a group of various G− and G+ bacteria the antibacteri ...

- Abstract:
- ... Eucalyptus robusta (Sm.) (ER) is a widely distributed tree native to the east coast of Australia, which has also been established in numerous other countries. ER leaves contain high levels of essential oils and are rich in total phenolic compounds (TPC), which have been linked with health benefits; however, there is limited information on the bioactivity of ER leaf extracts. This study aimed to op ...
