Psammaplysilla purpurea
 
Description The sponge Psammaplysilla purpurea (Order: Verongidae, Family: Aplysinellidae) is a well known source for several bromotyrosine alkaloids of unique structural features and exhibiting promising biological activities such as cytotoxicity, antimicrobial properties etc. Herein is reported isolation and structure determination of two such alkaloids: 16-debromo aplysamine-4 1 and purpuramine 1 2 from the sponge @iP. purpurea@@ collected from Mandapam, Tamil Nadu, India. The structures of these compounds were finalized from the respective spectral data including IR, UV-Vis, NMR and MS and their comparison with those of similar compounds from literature.
