undescribed compounds including three terphenylquinones (fendleryls A - C), one terphenyl (fendleryl D), and six novel drimane - phthalide-type lactone/isoindolinones derivatives (fendlerinines A - F) along with seven known compounds (2-O-methylatromentin, rickenyl E, atromentin, rickenyls C - D, (+)-ramulosin, and O-hydroxyphenyl acetic acid). The chemical structures were determined on the basis of spectroscopic
Hypoxylon 属是木兰科的成员,已知可产生显着的化学多样性的次生代谢物。此外,分离出的化合物也可作为化学分类特征用于区分两个部分,即sect。花环和教派。羟基磷灰石。在我们对新化合物的持续化学筛选计划中,H. fendleri BCC32408 的粗提取物在 HPLC 分析中给出了重要的化学特征。因此,然后对这些粗提取物进行了化学研究。调查导致分离出 10 种以前未描述的化合物,包括三种三联苯醌(芬德基 A - C)、一种三联苯(芬德基 D)、和六种新型 drimane - 苯酞型内酯/异吲哚酮衍生物(fendlerinines A - F)以及七种已知化合物(2-O-methylatromentin、rickenyl E、atromentin、rickenyls C - D、(+)-ramulosin 和 O-羟苯基醋酸)。化学结构是在光谱分析的基础上确定的,包括一维、二维核磁共振
