Lotus root attracts increasing attention mainly because of its phenolic compounds known as natural antioxidants. Its thirteen varieties were systematically analyzed on the content, distribution, composition and antioxidant activity of phenolic compounds for a better understanding of this aquatic vegetable. The respective mean contents of total phenolics in their flesh, peel and nodes were 1.81,...

Recently, plant material extracts containing phe­ nolic compounds have been screened as potential new sources of natural antioxidants. Beet extracts, especially the extracts from the peel, have shown strong antioxidant activity in these evaluations re­ sulting in increased attention to the natural pro­ ducts present in beetroot (Vinson et al., 1998; Kähkönen et al., 1999). As part of our ongoin...

This study provides new data on the various carotenoids found in bambangan (Mangifera pajang Kosterm.) peel and pulp extracts, such as all-trans-αand β-carotene, cis-β-carotene, 9-cis-β-carotene, and cryptoxanthin. Chemical and biological antioxidant assays were determined to evaluate the antioxidant capacity of bambangan peel and pulp extracts. Bambangan pulp had higher αand β-carotene content...

Dragon fruit peel can be utilized as a natural dye due to betacyanin content, redviolet pigment of betalain group. Betacyanin is unstable to temperature, oxygen, and light, consequently microencapsulation technology is required to maintain its stability. This study aims to determine microencapsulation efficiency of dragon fruit peel extract with variation of encapsulation ratio and to perceive ...

Heat treatment of persimmon peel (PP) increased the antioxidative activity of the 70% ethanolic extract (EE) and water extract (WE) from PP. EE and WE both prevented H2O2-induced DNA damage to human peripheral lymphocytes. The antioxidative and antigenotoxic activities of the PP extracts were significantly affected by heating.

the phenolic compounds of pomegranate (punica granatum l.) peel extracted by two methods (solvent and ultrasound-assisted) with five solvents (acetone, methanol, ethanol, water and ethyl acetate) were compared with supercritical fluid extraction (sfe). the total phenolic compounds were determined according to the folin-ciocalteu reagent using tannic acid as standard. the overall results showed ...
