cis-p-Coumaroylagmatine (1) was isolated from Albizzia julibrissin Durazz, a nyctinastic plant, as a leaf-opening substance. The compound was quite effective for opening the plant leaves at 5×10-6 M at night, but was not effective for other nyctinastic plants. The bioactive fraction with leaf-closing activity was also separated from the plant extract. Although the leaf-opening activity of the plant extract changed between the day and night, the content of 1 was almost constant through a 24-h day. These results suggest that the change in content of an unknown leaf-closing factor induced balance between the two leaf-movement factors through a 24-h day.
顺-对-香豆酰基丁胺 (1) 是从合欢 (Albizzia julibrissin Durazz)(一种夜眠植物)中分离出来的,作为一种开叶物质。该化合物对于夜间在 5×10-6 M 下打开植物叶子非常有效,但对其他夜行植物无效。具有闭叶活性的生物活性部分也从植物提取物中分离出来。尽管植物提取物的开叶活性在白天和晚上之间发生变化,但1的含量在一天24小时内几乎恒定。这些结果表明,未知叶子关闭因子含量的变化导致了 24 小时内两个叶子运动因子之间的平衡。
