“…The solvent systems employed included (1) chloroform-ethanol-heptane (1:1:1, v/v);[23] (2) n-butanol-acetic acid-water (50:15:35, v/v);[1] (3) n-butanol-acetic acid-water (100:20:48, v/v);[24] and (4) ethanol-methanol (50:50, v/v). [25] All experiments were performed at a temperature of 25°C ± 2°C with a tank saturation time of 1 h. The spots were sprayed with different reagents for the identification of products such as P -dimethylamino benzaldehyde spray, diazotization followed by alkaline beta-naphthol spray, diazotization followed by N-1-naphthyl-ethylenediamine spray, exposure to iodine vapors, and examination under UV light at 254 and 350 nm (Uvitec Lamp, UK).…”

“…Bu amaçla literatürde belirtilen bazı metotlardan (ı,4,5,7,8) yararlanıldı. (2). Bu bakımdan değişik solvan sistemlerinin ve değişik belirtme ayıraçlarının kullanılması yerine en uygun bir solvanın ve bdirtme ayıracının ince tabaka kromatografisi; çıkan metot ve sirküler kağıtkromatografisi olmak üzere üç tekniğe uygulanarak, yeri geldiği zaman imkanlara ve analizin amacına en elverişli olanının kullanılmasının daha yararlı olup olmayacağını araştırdık.…”
