Two new polyacetylenes from <i>Bidens parviflora</i>
Two novel polyacetylenic compounds were successfully separated from the dichloromethane extract of the aerial parts of <i>Bidens parviflora</i> Willd., known for its ethnomedicinal use in traditional Dai medicine. These compounds were structurally elucidated and identified as (2<i>R</i>)-trideca-3<i>E</i>,5<i>Z</i>,11<i>E</i>-triene-7,9-diyne-1,2,13-triol (<b>1</b>), and (2<i>R</i>)-trideca-11<i>E</i>-ene-5,7,9-triyne-1,2,13-triol (<b>2</b>). Their chemical structures were confirmed through a comprehensive analysis involving ultraviolet (UV) spectroscopy, infrared (IR) spectroscopy, high-resolution electrospray ionization mass spectrometry (HR-ESI-MS), as well as detailed one-dimensional (1D) and two-dimensional (2D) nuclear magnetic resonance (NMR) spectroscopic data, and measurements of specific optical rotation.
