We report the complexation of bovine serum albumin (BSA) with resveratrol, genistein, and curcumin, at physiological conditions, using constant protein concentration various polyphenol contents. FTIR, CD, fluorescence spectroscopic methods were used to analyze ligand binding mode, constant, effects on BSA stability conformation. Structural analysis showed that polyphenols bind via hydrophilic hydrophobic interactions number bound (n) being 1.30 for resveratrol-BSA, genistein-BSA, 1.0...
Crocetin (CRT) and dimethylcrocetin (DMCRT) are derived from crocins which found in the stigmas of saffron (Crocus sativus L.), while safranal is main component saffron's essential oil. The aim present study was to examine their interaction with human serum albumin aqueous solution at physiological conditions using constant protein concentration various ligand contents. FT-IR UV-visible spectroscopic methods were used determine ligands' binding mode, constant, effects complexation on...
Abstract A novel application of ultrasounds is presented for the improvement efficiency production FAME (or biodiesel) from materials not used so far this purpose, such as seed cakes. The novelty work introduction in situ derivatization assisted by (ultrasonically extraction transesterification) biodiesel production. Thus, TG contained solid material are extracted and immediately transesterified a methanolic solution 1 M NaOH an ultrasonic field. total yield seeds that contain greatly...
Grape is the largest fruit crop worldwide and grape pomace an important solid waste generated from pressing fermentation processes in wine industries. Wine industry residues are rich bioactive compounds and, this case, utilization of by-products for alternative uses has been a focus research. The aim present project to primary benefits winemaking new products focusing on pomace, as well discover novel applications food industry, cosmetics, pharmaceutical, agricultural, livestock fields...
The aim of this work was to propose a high-performance liquid chromatography with diode array detection (HPLC-DAD) method for determining the three main compounds responsible quality saffron (crocetin esters, picrocrocin, and safranal) by preparing an aqueous extract according ISO 3632 standard solve difficulty that has aroma taste determination ultraviolet-visible spectroscopy. Toward aim, laboratory-isolated safranal purity ≥ 88%, trans-crocetin di(β-D-gentiobiosyl) ester (trans-4-GG)...
In this work we have studied the volatile components of saffron, dried, dark-red stigmata Crocus sativus L. flowers. The isolation aroma, was achieved using following techniques: (a) steam distillation (SD), (b) micro-steam extraction (MSDE), and (c) vacuum head space method (VHS). determination performed some different gas chromatography−mass spectrometry (GC−MS) instruments methods. characteristic compounds are 2,6,6-trimethyl-1,3-cyclohexadien-1-carboxaldehyde, namely safranal;...
Safranal (2,6,6-trimethyl-1,3-cyclohexadiene-1-carboxaldehyde) is the main component of saffron's essential oil. It was obtained using microsimultaneous hydro distillation-extraction (MSDE) and by ultrasound-assisted extraction (USE), which a mild method. 4-Hydroxy-2,6,6-trimethyl-1-cyclohexene-1-carboxaldehyde (HTCC) precursor safranal in considerable amounts only USE. Five C(13)-norisoprenoids were found saffron for first time. Using gas chromatography technique, HTCC quantified from Greek...
Thyme honey is the most appreciated unifloral Greek in Greece as well around world. In an effort to investigate headspace composition of this type honey, 28 samples were analyzed by means solid-phase microextraction coupled a gas chromatography–mass spectrometry system. The botanical origin was ascertained pollen analysis, and displayed relative frequencies thyme between 18 41%. A total 62 compounds isolated, phenylacetaldehyde abundant (32.9% peak area). Possible markers are...
Abstract Flavonoids are strong antioxidants that prevent DNA damage. The anticancer and antiviral activities of these natural products implicated in their mechanism actions. However, there has been no information on the interactions with individual at molecular level. This study was designed to examine interaction quercetin (que), kaempferol (kae), delphinidin (del) calf-thymus aqueous solution physiological conditions, using constant concentration (6.5 mmol) various drug/DNA(phosphate)...
