Ultraviolet sunscreen compounds in epiphytic red algae from mangroves

  title={Ultraviolet sunscreen compounds in epiphytic red algae from mangroves},
  author={Ulf Karsten and Thomas Sawall and John West and Christian Wiencke},
Epiphytic red algae of the order Ceramiales from mangroves and salt marshes (nine species from Bostrychia, three from Stictosiphonia and four from Caloglossa) produce varying levels of the UV-absorbing compounds mycosporine-glycine, shinorine, porphyra-334, palythine, asterina-330 and palythinol, a suite of substances chemically assigned as mycosporine-like amino acids (MAAs). Mean MAA levels varied from 0.02 to 12.8 mg g−1 DW in field-collected and laboratory cultured specimens. While in field… CONTINUE READING
