三种新的聚丙酸酯代谢物，6Z,8E-Delta(8)-siphonarienfuranone (1)、6E,8E-Delta(8)-siphonarienfuranone (2) 和 6E,8E-3-羟基-4,6,8,10,12-pentamethylpentadeca-6,8-dien-5-one (3)，以及已知的聚丙酸酯 siphonarienfuranone (4)从南非潮间带海洋软体动物Siphonaria oculus中分离得到。有证据表明，在对该软体动物的丙酮提取物进行色谱处理时，1、2 和 4 可能是由无酰前体环化而成
Three new polypropionate metabolites, 6Z,8E-Delta(8)-siphonarienfuranone (1), 6E,8E-Delta(8)-siphonarienfuranone (2), and 6E,8E-3-hydroxy-4,6,8,10,12-pentamethylpentadeca-6,8-dien-5-one (3), and the known polypropionate siphonarienfuranone (4) were isolated from the intertidal South African marine mollusk Siphonaria oculus. Evidence is presented to suggest that 1, 2, and 4 may cyclize from an acylic precursor on chromatographic workup of the acetone extract of this mollusk
