Abstract

Heliotropium sclerocarpum Phil. (Heliotropiaceae) is a resinous bush that grows in the Atacama of northern Chile. The chemical composition of its resinous exudate was analyzed for the first time. One aromatic geranyl derivative: filifolinol (1), one flavanone: naringenin (2) and a new type of 3-oxo-2-arylbenzofuran derivative 3 were isolated and their structures were determined. The antioxidant activity of the phenolic compounds and resin was evaluated using the bleaching of DPPH radical method and expressed as fast reacting equivalents (FRE) and total reacting equivalents (TRE).

摘要

智利北部阿塔卡马沙漠生长的香脂硬实蔷薇树脂的化学成分分析。首次对其香脂状渗出物的化学成分进行分析。分离得到 1 种芳香基香叶基衍生物：filifolinol（1）、1 种黄烷酮：柚皮素（2）和 1 种新型 3-氧代-2-芳基苯并呋喃衍生物 3，并确定了它们的结构。采用 DPPH 自由基清除法评价酚类化合物和树脂的抗氧化活性，并以快速反应当量（FRE）和总反应当量（TRE）表示。
