AI Article Synopsis
- The study focused on purifying and identifying chemical constituents in the ethanol extract from Hypericum wightianum using advanced techniques like NMR and mass spectrometry.
- A total of 22 compounds were successfully identified, including new findings within the Hypericum genus, specifically compounds 16 and 17, and several that were first isolated from this particular plant species.
- The research also detailed the chiral resolutions and absolute configurations for compounds 1-4, marking the first report of these findings for these compounds.
Article Abstract
The chemical constituents in the ethanol extract of Hypericum wightianum(Hypericaceae) were purified by column chromatography and identified via magnetic resonance imaging(NMR), high-resolution mass spectrum, and circular dichroism. A total of 22 compounds were identified, including eight polyprenylated phloroglucinols(1-8), three chromones(9-11), and three terpenoids(14-16) and so on. Among them, compounds 16 and 17 were first reported in the genus Hypericum, and compounds 1-11, 14, 15, and 19 were first isolated from H. wightianum. Compounds 1-4 were previously reported as two pairs of enantiomers. This study reported the chiral resolutions and absolute configurations of compounds 1-4 for the first time.
