Abstract The structures of fruticulin A and its free phenol derivative, highly oxidized diterpenequinones isolated fromSalvia fruticulosa, were determined by spectroscopic methods, chemical transformations and X-ray crystallographic analysis of one of them. The structure of fruticulin B is revised to a linear arrangement as a result of an X-ray diffraction analysis.
摘要 采用光谱法、化学转化法和X射线晶体学分析方法确定了果皮素A及其游离酚衍生物,即从果皮丹参中分离得到的高度氧化的二萜醌的结构。作为 X 射线衍射分析的结果,果糖蛋白 B 的结构被修正为线性排列。
