title: A diterpenoid lactone from Aplysia juliana.
abstract: A new diterpenoid lactone, angasiol acetate [1], has been isolated from the sea hare Aplysia juliana collected from the Karachi coastline of the Arabian ocean. The structure, including the absolute configuration of 1, was determined by single-crystal X-ray diffraction and spectroscopic techniques.
