The concentrations and distributions of some typical chlorinated flame retardants (Dechlorane or Mirex, Dechlorane 602 (Dec 602), Dechlorane 603 (Dec 603), Dechlorane 604 (Dec 604) and Dechlorane Plus (DP)) and brominated FRs (polybrominated diphenyl ethers (PBDEs), pentabromoethylbenzene (PBEB) and 1,2-bis(2,4,6-tribromophenoxy)ethane (BTBPE)) were analyzed in surficial sediment collected from...

Purple corn seeds germinated at 25 °C and 35 for 5 days were used to obtain purple protein concentrate (PCPC25 PCPC35). PCPC25 PCPC35 subject gastrointestinal hydrolysis. PCPC its hydrolysates evaluate their functional biological properties. Total flavonoid content (TFC), total flavonol (TFLC), anthocyanin (TAC) proanthocyanin (TAP) determined. The polyphenols flavonoids identified by UPLC-QDa....

This paper is the first attempt to quantify the levels and the distribution pattern of lindane in the surface water, sediment and fish (Chrysichthys furcatus and Tilapia zilli). The samples were collected from three stations (Ovwian, Ekakpamre, and Ovu) of the Warri River in the western Niger Delta of Nigeria in 2006: during the dry (January-April) and wet seasons (May-August). The analysis inc...

The aim of this study was to determine the effect different drying methods on nutritional content and antioxidant activity purslane. Two purslane samples have been dried using four (sun, vacuum, hot air, freeze drying). Dried fresh were analyzed for their dry matter, β-carotene content, chlorophyll a b contents, total flavonoid flavonol phenolic %DPPH radical scavenge activity, metal chelating ...

Leaf area information is required in various horticultural and physiological studies and it will be more useful if done via non-destructive methods. The objective of this study was to establish equations to estimate leaf area (LA) using length (L), width (W), fresh weight (FW), dry weight (DW), length × length (L2), width × width (W2), length × width (L×W), length + width (L+W), fresh weight × ...

Banana, as the world’s most consumed fruit, is a good source of carbohydrate, potassium, fiber, and other essential nutrients such pro-vitamin A carotenoids. The carotenoid content composition in bananas commonly sold fruit shops Malang have become interesting studies. Five types banana, i.e. Berlin, Mas, Cavendish, Candi Raja were characterized using high-performance liquid chromatography UV-V...

This paper describes the antioxidant and antimicrobial activities and phenolic components of different solvent (absolute methanol, absolute ethanol, absolute acetone, 80% methanol, 80% ethanol, 80% acetone and deionized water) extracts of leaves, flowers and bark of Gold Mohar [Delonix regia (Bojer ex Hook.) Raf.]. The extract yields from leaves, flowers and bark ranged from 10.19 to 36.24, 12....

The polyphenolic profile of leaves and stalks of Perilla frutescens, was assessed as a source of natural antioxidants. The amount of caffeic and rosmarinic acids, determined by high-performance liquid chromatography (HPLC), were 0.51 mg/g dry weight (DW) and 2.29 mg/g DW, respectively. The measurement of scavenging capacity against the 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABT...

There is increasing concern about the toxicities and potential risks, both still poorly understood, of silver nanoparticles for the aquatic environment after their eventual release via wastewater discharges. In this study, the toxicities of sediment associated nano (<100 nm)-, micron (2–3.5 μm)and ionic (AgNO3)-Ag on the sediment-dwelling polychaete, Nereis diversicolor, were compared after 10 ...

white clover is positively correlated with increased size of plant parts and reduced leaf density per unit area The plasticity of white clover (Trifolium repens L.) results in (Beinhart et al., 1963). changes in plant habit in response to different environmental stresses. The objective of this research was to characterize those morphological Defoliation through grazing or clipping is a managech...
