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.
