Method for the determination of rutin , myricetin , quercetin , kaempferol , apigenin , pinocembrin , chrysin , galangin contents in propolis - lc - ms - ms detection method and lc - uv detection method 蜂胶中芦丁杨梅酮槲皮素莰菲醇芹菜素松属素苛因高良姜素含量的测定方法液相色谱-串联质谱检测法和液相色谱-紫外检测法
Though not definitively proven to work , she often prescribes coenzyme q10 , vitamins e and b6 , quercetin and garlic because laboratory studies have suggested they may be beneficial 她也经常开出服用辅酶q10 ，维生素e和b6 、槲皮苷和大蒜的处方，尽管不能确定它们是否有效，但实验室研究已表明它们对患者是有益的。
Through spectrum analysis , its molecular formula is determined as c2oh32o3 . the further structural identification of this compound is in progress . meanwhile , quercetin has been isolated and its content determined by hplc 同时证明了马尾松松叶中含有槲皮素，并利用高效液相色谱法对其进行了含量测定，结果为0 . 0013 。
Consistent amounts of resveratrol , quercetin and ellagic acid will help improve cardiovascular health and may even confirm what the french have known all along ? that drinking red wine is good for you 一定总量的白藜芦醇，橡黄素和糅花酸可以改善心脑血管疾病，还可以让法国人更加坚信他们一直相信的事? ?喝红葡萄酒有益健康。
In our experiments , however , the inhibition of flavonoid on root system development is related to high nitrate , and quercetin , one kind of flavonoid , does not inhibit but promotes the gravitropism instead 但我们在实验中发现，类黄酮对根系发生的抑制是与高n相联系的。对于向地性，类黄酮中的一种? ? quercetin不但不抑制，反而促进向地性? ?诱导超向地性。
Like vitamin c , quercetin has strong antioxidant properties ? but it is also believed to prevent the release of histamine , thus potentially helping to stop inflammation and swelling of airways and the production of excess mucus 和维生素c一样，槲皮素具有较强的抗氧化性能，但它也被认为可以阻止组胺释放，从而可能有助于阻止气道的发炎、肿胀及产生过多粘液。
Several common extractioin methods for quercetin from sophora japonica buds are introduced . and its effects on central nervous system are summarized in the paper , including analgetic result , anti - despondent result and effect on memory 介绍了槐米中槲皮素的几种常规提取方法,并概括了槲皮素作用于中枢神经系统方面的功效,包括其镇痛作用、抗抑郁作用及对记忆的影响。
On the one hand , quercetin promotes hypocqtyls phototropic growth , on the other hand , it promotes gravitropism of root tips . when the seedlings are placed tilted at 80 , quercetin induces root tips getting into medium , while on control case , it grows along the surface 一方面q促进了下胚轴的向光生长，另一方面，促进了根尖的向地性，在80培养时， q诱导根尖钻入培养基中。
There were different kinds of apple polyphenolics with different varieties of gala and golden . as it is known , the anthocyanidin is only in gala skin but not in golden skin . it is found in this study that there has quercetin in golden pulp but not be detected in gala pulp 嘎拉和金冠中多酚化合物种类不同，已知嘎拉果皮中含有花青素-山越橘苷，而金冠中没有；本实验发现金冠果肉中含有槲皮苷，而嘎拉果肉中没有检测到。
Green tea contains a number of flavonols with the basic structure specific flavonols found in tea include myricetin ( hydroxyls at carbon 3 ' , 4 ' , and 5 ' ) , quercetin ( hydroxyls at positions 3 ' and 4 ' ) , and kaempferol ( hydroxyl at position 4 ' ) , and their glycosides 绿茶含有一些黄酮醇，其基本化学结构为:茶中特有的黄酮醇有杨梅黄酮( 3 ' 、 4 ' 、 5 '碳位上羟基化) 、豕草花粉苷( 3 '和4 '碳位上羟基化) ，莰非醇( 4 '碳位上羟基化) ，以及它们的糖苷物。
