WebSulfuric acid (H 2 SO 4) and other reagents, such as n-butanol and acetic acid, were obtained from commercially available sources and used without further purification. The 1 H and 13 C NMR spectra were obtained in D 2 O solvent using a Bruker AVANCE III 400 MHz NMR Spectrometer with TMS as the internal standard. WebThe separations were performed with two different solvent systems composed of 1-butanol-acetic acid-water (4:1:5, v/v) (BAW) and hexane-ethyl acetate-methanol-0.1 M HCl (1:1:1:1, v/v) (HEMW) using dipeptides and DNP-amino acids as test samples, respectively. WebFeb 20, 2024 · For the purification of root extracts, solvent systems had 50% water, 40% (on average) n -butanol and the rest was ethyl acetate, with only one or two PhGs isolated in a single run. Separation of up to five PhGs requires more non-polar solvent systems based on 45% water, 25-0% n -butanol, 25–50% ethyl acetate and 5% ethanol. sans software supply chain risk management
