Synthesis and spectral analysis of 5,7-dihydroxy-3-(4-hydroxybenzyl)-6,8- dimethylchroman-4-one

Abstract

An efficient and concise synthetic route is designed based on 5,7-dihydroxy-3-(4-hydroxybenzyl)-6,8-dimethylchroman- 4-one, an important active ingredient extracted from Polygonatum Odoratum (Mill.) Druce. In this regard, spectroscopic techniques such as 1H and 13C NMR and high-resolution mass spectrometry are also performed to confirm the final structure. Also, micro-infrared spectroscopy and micro-Raman spectroscopy are performed to further determine the structure of the compound.
