The conditions for microwave-assisted extraction (MAE) of total flavonoids (TF) and total phenols (TP), and antioxidant activity from celery (Apium graveolens L.) leaves by response surface methodolog...
Total phenolics and flavonoids contents in Chinese wild rice were predicted using Near Infrared (NIR) spectroscopy as a rapid method. A Partial Least Square (PLS) algorithm was applied to perform the ...
Flavonoids are phytochemicals characterized by a wide range of biological activities, including antioxidant activity, the ability to modulate enzyme or cell receptor activity patterns, and to interfer...
为了提高枸杞中黄酮类化合物的提取效果,通过超声波细胞粉碎仪的强化作用,对枸杞中的黄酮类化合物进行提取研究,通过单因素和正交试验确定最佳工艺参数。结果表明,最佳提取工艺参数为:乙醇体积分数80%,液料比50mL/g,超声波工作/间歇时间3s/1s,超声波功率500W,提取时间50min。在此条件下提取率达到89.87%。
Our blueberry cultured cells produce anthocyanins in high quantity (Nawa et al., Biosci. Biotech. Biochem., 57, 770-774, 1993). Using high performance liquid chromatography/mass spectrometry (LC-MS), ...
The effect of dietary flavonoids (flavone, isoflavone, flavanone, chalcone, flavonol, and flavonol derivatives) on the differentiation of 3T3-L1 adipocytes was investigated. Glycerol-3-phosphate dehyd...
Niihime fruit, produced in the coastal area of the Sea of Kumano in Mie prefecture, is a new sour citrus fruit. This is the first study to examine the characteristics of the flavonoids in niihime frui...
We examined the effects of orally administered flavonoids isolated from buckwheat (Fagopyrum esculentum Moench) sprouts in restrained mice. These flavonoids have been shown to have antioxidant activit...
The (S)-hydroxynitrile lyase from leaves of the rubber tree Hevea brasiliensis (HbHnl) (EC 4.1.2.39) catalyzes the industrially interesting formation of (S)-cyanohydrins from aldehydes or ketones and ...
Quercetin is a known specific inhibitor of hsp70 synthesis and thus might be a potent agent for enhancing the selective cytotoxicity of heat on tumour cells. A comparative analysis of the effects of q...
Flavonoids are phytochemicals exhibiting a wide range of biological activities, among which are antioxidant activity, the ability to modulate activity of several enzymes or cell receptors and possibil...
Twelve sesquiterpenoids, one of which was a new compound, six tirucallane-type triterpenoids, and four flavonoids were isolated from the fruits of Schinus molle L. (Anacardiaceae). Their chemical stru...
Several flavonols were chemically transformed upon treatment by Trametes versicolor laccase; the majority of the major oxidation products were isolated (HPLC) as pure compounds and their structures un...
