Ultraviolet-Visible Spectroscopy and Chemometric Strategy Enable the Classification and Detection of Expired Antimalarial Herbal Medicinal Product in Ghana

<div>Selectivity ratio plot of UV-Vis spectra of liquid HMP obtained from DIVA test showing feature importance to discrimination between classes (<i>y</i>-axis) and wavelength (<i>x</i>-axis). Wavelengths, at which the SR is less than the threshold (red line), were eliminated from the data.</div>
