| Abstract: | A simple and reliable HPLC-DAD method for qualitative and quantitative determination of sesquiterpenes in Laurencia tristicha and L. okamurai was developed, and then applied to compare the sesquiterpenes in the two alga species. Except for the difference in content, L. tristicha and L. okamurai are very similar in chemical compositions. The content of laurinterol, the most abundant component in both species, is much higher in L. okamurai than in L. tristicha, while debromolaurinterol and aplysinol are the second abundant components of L. tristicha and L. okamurai, respectively. The current results confirmed the great chemotaxonomic importance of laurane-type sesquiterpenes, especially the main constituents of laurinterol, debromolaurinterol, and aplysinol, for L. tristicha and L. okamurai. |
