(A,B) Nano-LC-UV profiles of the hemp extracts. Experimental conditions: capillary columns (100 µm × 15 cm) packed with ChromSpher C18 dp 3 µm; mobile phase, ACN/H2O/formic acid, 80/19/1% (v/v/v). UV detection, 214 nm; injection time, 30 s; flow rate, 550. The samples here reported, were subjected to a dynamic maceration (DM) extraction procedure, with the exception of samples 4 and 5, which were subjected to the hydro-alcoholic extraction procedure (HAE).
