From the CHCl_3 soluble part of MeOH extractives of the body walls of marine mollusk, Aplysia kurodai, collected along the coast of Fukuoka, two isoprenoids, aplykurodin A(1) and B(2) and four halogenated terpenoids (3)-(6) were obtained. The structure of aplykurodin A(1) was determined on the basis of chemical and spectral data and X-ray crystallographic analysis. The absolute stereostructure of 1 was elucidated by means of the CD analysis. Aplykurodin B(2) is dehydrocompound of 1. The relative stereostructures of 3,4 and 5 were verified by comparison of their spectral data with those of the known compounds. The structure determination of 6 is in progress. To the author's knowledge, 1 and 2 are new isoprenoids which are presumed to be the related compounds of steroids. 3 and 5 are also new halogenated monoterpenoids.
