Six new macrocyclic sesterterpenoids 1–6 were isolated from the secretion of a scale insect, Ceroplastes ceriferus Anderson, and their structures determined. Chemical correlation has also been accomplished. Stereochemistry was elucidated by comparison of the CD spectra of the ozonolysis product of 1-acetate and a corresponding synthetic substance of known absolute configuration.
从鳞片昆虫Ceroplastes ceriferus Anderson的分泌物中分离出六个新的大环酯类化合物1–6,并确定了它们的结构。化学相关性也已经完成。通过比较1-乙酸盐的臭氧分解产物和相应的已知绝对构型的合成物质的CD光谱,阐明了立体化学。
