Eleven essential oils, namely, Cananga odorata (Annonaceae), Cupressus sempervirens (Cupressaceae), Curcuma longa (Zingiberaceae), Cymbopogon citratus (Poaceae), Eucalyptus globulus (Myrtaceae), Pinus radiata (Pinaceae), Piper crassinervium (Piperaceae), Psidium guayava (Myrtaceae), Rosmarinus officinalis (Lamiaceae), Thymus x citriodorus (Lamiaceae) and Zingiber officinale (Zingiberaceae), wer...

The aim of the present study was to investigate the antioxidative potential of components extracted from the indigenous medicinal mushroom, Schizophyllum commune, using solvents of different polarities. The effectiveness of antioxidants in each solvent fraction was evaluated by quantitating the total phenolic content, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, cupric ion ...

Chia (Salvia sp) seeds were investtgated as a source of natural lipid antioxidants. Methanolic and aqueous extracts of defatted chia seeds possessed potent antioxidant activity. Analysis of 2 batches of cbia-seed oils demonstrated marked difference in the fatty acid composition of the oils, In both batches, the oils had high concentrations of polyunsauarated fatty acids. The major antioxidant a...

In this study, the bioactive compounds of loquat fruit (Eriobotrya japonica Lindl.) skin and pulp extracted by two extraction methods (solvent and ultrasound-assisted) with three solvents (ethanol, water and ethanol-water) were compared to supercritical fluid extraction. The antioxidant activities of skin and pulp extracts were evaluated and compared to tertiary butylhydroquinone (TBHQ) using 2...

Abstract Carotenoids were recovered from carrot processing waste using sunflower oil. Simplex centroid mixture design was applied for the optimization of wall material formulations (whey protein/maltodextrin/inulin) encapsulation extract by freeze drying (FD) and spray (SD). The optimal materials pure whey protein , 71 g/100 g - 29 g/100 g inulin mixture, respectively, showing total carotenoids...

Carotenoids are constituents of the photosynthetic apparatus and essential for plant survival because of their involvement in protection of chlorophylls against photooxidation. Certain classes of herbicides are interfering with carotenoid biosynthesis leading to pigment destruction and a bleached plant phenotype. One important target site for bleaching herbicides is the enzyme phytoene desatura...

The ethanolic extract of Aloe vera leaf skin was fractionated by liquid-liquid partition using hexane, ethyl acetate, chloroform-ethanol and butanol. The total phenolic content of the four different fractions were determined by Folin-Ciocalteu method and their antioxidant activity was essayed through some in vitro models such as the antioxidant capacity by phosphomolybdenum method, β-carotene b...

Phytoene desaturase (PDS) is an essential plant carotenoid biosynthetic enzyme and a prominent target of certain inhibitors, such as norflurazon, acting as bleaching herbicides. PDS catalyzes the introduction of two double bonds into 15-cis-phytoene, yielding 9,15,9'-tri-cis-ζ-carotene via the intermediate 9,15-di-cis-phytofluene. We present the necessary data to scrutinize functional implicati...

Preservative fruits have gained popularity in recent years as part of food consumption, but their benefits towards human health are not known. This study compared total phenolic (TPC), total flavonoid (TFC), β-carotene, lycopene, ascorbic acid (AA) contents and antioxidant properties between fresh and pickled papaya. The results indicated that mean TPC (mg gallic acid equivalent/100 g dry sampl...
