摘要:
Structural studies of four new sesquiterpenes, 3β-angeloyloxy-6β-(3-methylbutanoyloxy)- and 3β,6β-bis(angeloyloxy)furanoeremophilan-14-als and 3β-angeloyloxy-6β-(3-methylbutanoyloxy)- and 3β-angeloyloxy-6β-(3-methylpentanoyloxy)furanoeremophilan-14-oic acids, together with 3β,6β-bis(angeloyloxy)furanoeremophilan- 14-oic acid from Syneilesis palmata (Thunb.) Maxim, are described.
