Cembranoids Content of Soft Coral Sarcophyton from Acidified Environment at Volcano Island, Indonesia
Abstract: Cembranoid content
in soft coral is known as a chemotype that relate with genotype and
environment. This research aimed to characterize the cembranoid Sarcophyton
soft coral from the reef that acidified by CO2 volcanic vents (pHT 7.8) at
Volcano Islands waters, Banda-Neira (Indonesia), as a means of predicting the
future impact of ocean acidification to the genetic diversity of Sarcophyton
soft coral. 30 random colonies were taken, combined, and extracted with
ethanol. Cembranoid isolation and identification had been done by high
performance liquid chromatography and spectroscopic techniques. Results of the
study found sarcophytol derivatives (sarcophytol A, 11,12-epoxy sarcophytol A,
sarcophytol B, and sarcophytol M) as the only chemotype in the sample. This may
suggest low genetic diversity in the observed Sarcophyton sample. Therefore, it
may suggest that even soft coral is known to be resilient to future
acidification pressures, the genetic diversity or the production of diverse
cytotoxic metabolite may be hampered due to ocean acidification in future
climate change adaptation.
