Taraxeryl <i>cis-</i> and <i>trans-p-</i> hydroxycinnamates from <i>Bruguiera gymnorrhiza,</i> and their chemical structure elucidation techniques (cSET) through comparative spectral studies (CSS)

We report herein the occurrence of two known compounds, taraxeryl <i>cis</i> (<b>1</b>)<i>-</i> & <i>trans</i> (<b>2</b>)<i>-p</i> hydroxycinnamates however, for the first time from the leaves of <i>Bruguiera gymnorrhiza.</i> Based on the recent reports (until 2025), firstly the trends in the recent works, secondly the chemical Structure Elucidation Techniques (cSET) through Comparative Spectral Studies (CSS), and thirdly the bio-prospect of both the isomers have been presented. Further, to fill-in the limited discussion on IR of <b>1</b> and <b>2</b> in earlier reports, this paper elaborated the FTIR spectra with the intricacies of interfering group, alternate option bands etc. Further, in-between the ¹H and ¹³C NMR, some valuable spectral differences have been re-visited and, the broader usability of ¹H NMR over ¹³C NMR has been tipped-off. With hands on examples of <b>1</b> and <b>2</b>, our approach to cSET-CSS might equally attract the teachers, students, and the early career researchers especially within the teaching-learning landscape.
