Ceriops decandra is a mangrove of the family Rhizophoraceae. It is widely distributed
isolation and structural elucidation of an unprecedented C9-spiro-fused 7,8-seco-ent-abietane, named decandrinin (1) (Figure 1), from the bark of an Indian mangrove, C. decandra, collected in the estuary of Godavari, Andhra Pradesh. The absolute stereostructure of 1 was established by HRMS (ESI), extensive
