Paralemnolins V and W, New Nardosinane-Type Sesquiterpenoids from a Bornean Soft Coral, Lemnalia sp.

Two new nardosinane-type sesquiterpenoids, paralemnolin V ( 1 ) and paralemnolin W ( 2 ), along with five known sesquiterpenoids ( 3–7 ), were isolated from a population of Bornean soft coral Lemnalia sp. The structures of these metabolites were elucidated based on their NMR and HR-ESI-MS spectral data. These compounds were subjected to antibacterial and antifungal tests against eight bacterial and seven fungal strains.
