Objective: To develop a RP-HPLC method for simultaneous determination of three active compounds, dictamnine, obacunone and fraxinellone in root bark of Dictamnus dasycarpus and supply a reference for the establishment of the quality standard of D.

中文摘要：目的：建立同时测定白鲜皮中白鲜碱、黄柏酮和梣酮含量的反相高效液相色谱法，为中药白鲜皮标准的制定提供依据。

Quercetin is one of the effective components contained in sophora japonica flower bud.3-hydroxy 4-carbonyl,4-carbonyl 5-hydroxy,and 3′,4′-dihydroxy groups of quercetin could be become chelating position with metal.

槲皮素（3，5，7，3′，4′－五羟基黄酮）是中药槐花蕾的有效成分之一。槲皮素的3－羟基4－酮基，5－羟基4－酮基及3′，4′－二羟基均为可络合部位。

Several healthy effects of hesperidin and other citrus flavanoids such as naringenin, diosmin, nobiletin, etc, have been described either in vitro assays or in animal and human clinical trials.

橙皮苷和其他柑橘类黄酮的一些健康的作用，如柚皮素，地奥司明，川陈皮素等，无论是在体外实验或动物和人类的临床试验已经说明。

The studies on separation of antibacterial substances and the identification by GC-MS indicate that: Eleocharis Tuberoses peel contains cholesterol, organic acids, eaters and flavonoids four types of active ingredients, and 11kinds of active material.

对荸荠皮抑菌物质纯化后进行的GC-MS鉴定结果显示：荸荠皮抑菌物质中含有甾醇类、有机酸类、酯类和黄酮类4类活性成分共11种活性物质。

Ingredients: Alfalfa Sprout 80g, sweet potato leaves 75g, gynura 75g, pineapple 150g, 1 apple, 1 tomato, 30 pine nuts, black sesames 10g, mix grain powder 8g each, soup (Astragalus membranaceus Bunge, red jujube, Matrimony vine) 200c.c.

材料：苜蓿芽80g 、地瓜叶75g 、红凤菜75g 、菠萝150g 、苹果1个、大西红柿1个、松子30粒、黑芝麻粉10g 、三宝粉各8g 、黄蓍红枣枸杞汤200cc 。苹果洗净去皮、核、切块；西红柿洗净去蒂切丁；菠萝去皮切块；苜蓿芽、地瓜叶、红凤菜洗净、切碎。

By the quantitative analysis of flavonoids from the extract under acid hydrolysis condition, it is demonstrated that the level of isoquercitrin degrades along with the content of hydrochloric acid elevating and the level of kaempferol is reverse. Those reveal that there exist flavonoid conjugates whose aglycone is kaempferol in the leaves.

对青钱柳酸水解液中成分的测定表明，随着酸浓度的提高，异槲皮苷的含量下降，槲皮素的含量上升，山奈酚的含量也随酸浓度上升而增高，表明青钱柳中尚有以山奈酚为苷元的黄酮苷存在。

The results from statistical analysis of variance indicated that Bt toxin in Bt transgenic cotton had no negative effect on synthesis of flavonoids (mainly rutin, isoquercitrin and quercetin ).

显著性分析发现，外源Bt杀虫蛋白表达对棉花原有的芸香苷、槲皮素和异槲皮苷等抗虫黄酮类化合物不存在不利的影响。

Three flavonoids compounds: kaempferol *!, quercetin *, and isoquercitrin *# were isolated from the leaves of Cyclocarya paliurus Batal.

采用溶剂萃取及多种色谱技术分离纯化，根据理化性质和光谱分析方法鉴定其结构，确定从青钱柳中分离得到山柰酚、槲皮素和异槲皮苷 3个黄酮单体化合物，并用反相高效液相色谱法对其含量进行了测定，测得各自在甲醇和水提取物中的含量：山柰酚 0 。

Results showed a close relationship existed among the three flavonoid compounds with kaempferol content greater than quercetin and isoquercetin.

结果表明：青钱柳叶中3种黄酮类化合物质量分数紧密相关，其中山奈酚质量分数高于槲皮素和异槲皮苷。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
