It has been used in the extraction, isolation, and clean-up of several compounds present in complex matrices, as in the analysis of veterinary drugs, such as anthelmintics [17-19], benzimidazoles (BZDs) [20], nitroimidazoles [21], sulfonamides (SAs) [22, 23], quinolones (QNs) [24], tetracyclines (TCs) [25], nonsteroidal anti-inflammatory drugs (NSAIDs) [26, 27], and [beta]2-agonists [28,29] present in animal tissues, foodstuffs, lacteous products, and water.

Or instead, I would tender, the Romans may have partially translated their via lactea from Eratosthenes' kyklos galaxias 'circle of milk,' from which we derive galaxy, now a generic term for the Milky Way, though formerly our specific term; and kyklos galaxias may further be the source of our obsolete English calque, lacteous circle, which would support this hypothesis.
