- 中文摘要: A thorough investigation of Ligulariopsis shichuana afforded five new sesquiterpenes, including 1β,10β-epoxy-3α-angeloyloxy-9β-acetoxy-8α,11β-dihydroxybakkenolide (1), 1β,7-dihydroxy-3β-acetoxynoreremophil-6(7),9(10)-dien-8-one (2), 8α-hydroxy-3-oxoeremophil-1(2),7(11),9(10)-trien-8β(12)-olide (3), 1β,10β-dihydroxy-3β-acetoxyeremophil-7(11),8(9)-dien-8(12)-olide (4) and 1β,10β-epoxy-8,12-dihydroxy-3β-acetoxy-9β-angeloyloxyeremophil-7(11)-en-8,12-disemiketal (5). Their structures were established by spectroscopic methods and 2D NMR techniques. In addition, bakkenolide (1) and eremophilenolides (5) showed antibacterial and cytotoxic activities.
