| Abstract: | Chemical investigation of a Chinese collection of marine red alga Symphyocladia latiuscula yielded two new highly brominated phenols. The structures of the new compounds were elucidated by detailed spectroscopic analysis, including HRMS, 1D and 2D NMR and MS methods. Compounds 1 and 2 were evaluated for radical scavenging capability by 1,1-diphenyl-2-picrylhydrazuyl (DPPH) radical with the IC50 value of 14.5 and 20.5 μg/mL, respectively. |
