The two metabolites, Aaptamine(1) and Demethyl(oxy)aaptamine(2) were isolated from marine Sponge Luffariella sp., collected in October 1992, Manado Bay, Sulawesi in Indonesia showed in vitro activity against KB cancer cell line. Their structures were elucidated by $^1H-$, $^{13}C-NMR$, $^1H-^{13}C$(1 bond) heteronuclear multiple quantum coherence spectroscopy(HMQC), electron ionization mass spectroscopy(EIMS), ultra-violet spectroscopy(UV) and infrared spectroscopy(IR).

The three metabolites, Germacrene alcohol(1), Aaptamine(2) and Hexacyclic terpene(3) were isolated from Marine Sponge Luffariella sp., collected in October 1992, Manado Bay, Sulawesi in Indonesia showed in vitro activity against KB cancer cell line, and structure assignment for 1 was corrected by comparison of their spectral data with the literature $values^1$. Their structure were elucidated by $^1H$, $^13C$ NMR, $^1H$ $^13C$(1 bond) Heteronuclear Multiple Quantum Coherence Spectroscopy$(HMQC)^2$, $^1H$ $^13C$(2 and 3 bond) Heteronuclear Multiple Bond Correlation Spectroscopy$(HMBC)^3$, Electron Impact Mass Spectroscopy(EI ms), Ultra-violet Spectroscopy(UV) and Infrared Spectroscopy(IR).
