Hydroquinone has been identified as a phagostimulating pheromone,and it has been considered that all the Isoptera produce and employ hydroquinone as phagostimulating pheromone,irrespective of taxonomic position and biological traits.

目前，已确定对苯二酚为白蚁诱食信息素，且认为整个等翅目昆虫都产生和使用对苯二酚作为诱食信息素，与分类地位和生物学特性无关。

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。
