Colchicum lusitanum

Phenol materials in apple juice have been recovered with methanol from polyamide columns (at40 C) after elution of sugars and acids with water (10). Column chromatography on alumina has been used as a first step in the identification of phenolic material from Colchicum lusitanum (II). Extrelut 20 columns have been employed in the enrichment of phenolic acids in urine from the metabolism of catecholamines (12). And in the determination of phenol and o-cresol in fresh urine, solvent extraction with diethyl ether or dipropyl ether has been used following a preliminary hydrolysis with 60% perchloric acid (13).
