Abstract

Fractionation of the EtOH extract from the fruits of Broussonetia papyrifera led to the isolation of 15 phenolic compounds (1-15). Their structures were identified using spectroscopic methods. Among these compounds, 1 and 2 are new and 3-15 were isolated from this plant for the first time. Antioxidant activities of compounds 2-15 against H(2)O(2)-induced injury in SY5Y cells and 1,1-diphenyl-2-picrylhydrazyl radical scavenging activities were evaluated.

摘要

对构树果实的乙醇提取物进行分离，得到了15种酚类化合物（1 - 15）。通过光谱方法确定了它们的结构。在这些化合物中，1和2是新化合物，3 - 15是首次从该植物中分离得到。评估了化合物2 - 15对H(2)O(2)诱导的SY5Y细胞损伤的抗氧化活性以及对1,1 - 二苯基 - 2 - 苦基肼自由基的清除活性。
