실험 절차

A solution of 100 mg of auramycin C in 50 ml of 0.5% hydrochloric acid was hydrolysed at room temperature for 60 minutes. The reaction mixture was neutralised by dilute sodium hydroxide solution, extracted with 100 ml of chloroform twice and concentrated in vacuo to a small volume. The concentrate was chromatographed with thin layer chromatography plates (chloroform:methanol, 5:1). The band containing auramycin D was scraped off and extracted with a solvent mixture of chloroform and methanol (4:1) and concentrated in vacuo to dryness yielding 72 mg of auramycin D.
