NADES Compounds Identified in <i>Hypoxis hemerocallidea</i> Corms during Dormancy

Soaking <i>Hypoxis hemerocallidea</i> corms in distilled water improved the propagation and development of cormlets, suggesting the potential leaching-out of inhibitory chemical compounds. To investigate the presence of inhibitory compounds, nuclear magnetic resonance (NMR) spectral data...

description Soaking <i>Hypoxis hemerocallidea</i> corms in distilled water improved the propagation and development of cormlets, suggesting the potential leaching-out of inhibitory chemical compounds. To investigate the presence of inhibitory compounds, nuclear magnetic resonance (NMR) spectral data of the leachate from dormant <i>H. hemerocallidea</i> corms were obtained using a 600 MHz <sup>1</sup>H-NMR spectrometer. The <sup>1</sup>H-NMR analysis led to the identification of choline, succinate, propylene glycol, and lactose, as inhibitory compounds. These four chemical compounds are part of the “Natural Deep Eutectic Solvents” (NADES) that protect plant cells during stress periods, each of which has the potential to inhibit bud growth and development. These compounds are supposedly leached out of the corms during the first rain under natural conditions, possibly accompanied by changes in the ratios of dormancy-breaking phytohormones and inhibitory compounds, to release bud dormancy. The identified chemical compounds heralded a novel frontier in the vegetative propagation of <i>H. hemerocallidea</i> as a medicinal plant, and for its enhanced sustainable uses.
