Diversity of halogenated metabolites in red algae, laurencia snackeyi, collected from Dinawan and Lankayan Island

Diversity of halometabolites in red algae Laurencia snackeyi collected from two different locations, Dinawan and Lankayan Island was investigated through chemical analysis. A total of four pure compounds were isolated from the Dinawan Island's sample which identified as the (1) Palisadin A, (2) 5-acetoxypalisadin B, (3) Palisain B, and ( 4) Aplysistatin. These compounds were synthesized in significant quantity, 14.66%, 9.42%, 3.67% and 2.14% of5.18 g of crude extracts, respectively. However, Laurencia snackeyi from Lankayan Island was found to contain five compounds such as compounds (1 ), (2), (3), (4) with additional compound (9) which was identified as sp-hydroxypalisadin B. These compounds were found in significant quantity, 5.53%, 6.50%, 7.08%, 2.69% and 4.51% of 7.90 g of crude extracts, respectively. From this study, it is concluded that the diversity of halogenated metabolites in Laurencia Snackeyi from Lankayan Island is richer than the Dinawan Island
