摘要：

Two new sesquiterpenes, oculiferane (1) and epi-obtusane (2) have been isolated and identified from an acetone extract of the digestive gland of the sea hare, Aplysia oculifera. The structures were elucidated by spectroscopic analysis including HREIMS, H-1, C-13, DEPT, H-1-H-1 COSY, HMQC, and HMBC NMR; the relative configuration was confirmed by X-ray analysis. Compounds 1 and 2 exhibited cytotoxic activity in vitro against several human cancer cell lines with IC50 values in the low mu g/ml range. (C) 2014 Elsevier Ltd. All rights reserved.
