Optimization of the extraction of polyphenols from grape seed meal by aqueous ethanol solution
Receipt 10 January 2003, accepted 28 April 2003. Abstract The efficient methods for extracting phenolics from grape seeds have been of great interest to many investigators, due to the special health promoting and disease preventing effects of polyphenols. In this study, extractions were performed by using aqueous ethanol. The effects of single factors such as the concentration of ethanol, the r...
متن کاملAmino Acids in Aqueous Solution
In the previous chapter, the focus was mainly on the behavior of ions in solution. The effect of concentration, solvent, as well as pH have been investigated; furthermore, alkali metal ions as well as transition metal ions have been studied. In this chapter, the investigation will be extended from ions to molecules, more specifically toward the behavior of amino acids in solution. Amino acids a...
متن کاملQuantification of Bacterial Fatty Acids by Extraction and Methylation.
This protocol describes two similar methods for the extraction and methylation of fatty acids from bacterial cultures. The acid derivatization protocol (Lennen et al., 2013; Bligh and Dyer, 1959) results in the extraction and methylation of all fatty acids, both free and bound, from a bacterial culture, while the base derivatization protocol (Lennen and Pfleger, 2013) captures only bound (phosp...
متن کاملInvestigate formation constant of some Amino Acids by p-sulphonato-calix (4) arene in Aqueous Solution
The formation constants (log K), of the complexes formed between a number of amino acids(glycine , L-valine and L-alanine) with p-sulfonatocalix [4] arene at varying temperatures (25± 0.1to 65 ± 0.1 °C) in aqueous solutions and at natural pH of p-sulphonato-calix [4] arene (pH=3.2) bymeans of UV-Vis spectrophotometeric technique have been investigated. At this pH the guestmolecule is in its cat...
متن کاملAdsorption of Zn (II) from aqueous solution by using chitin extraction from crustaceous shell
Removal of toxic heavy metals from wastewater is an important environmental challenge. In this Study, Zn (II) removal from aqueous solution by chitin extraction from crustaceous shells (shrimp and crab) was investigated. The biosorption studies were determined as a function of contact time, pH, initial metal concentration, and the amount of adsorbent. Adsorption of Zn (II) increased with decrea...
