Abstract
Vitamin K5 (2-methyl-4-amino-1-naphthol hydrochloride) has been determined by gas chromatography using 2 different approaches. The 1st method is to determine K5 as its trimethylsilyl ether (TMS) derivative. The 2nd is to determine it as Vitamin K3 (2-methyl-l,4-naphthoquinone or manadione). The determination of vitamin K5 as such presents difficulties because of the hydroxyl and amino groups; however with the use of the trimethyl-silyl ether derivative these difficulties are overcome. Vivamin K5 is determined as vitamin K3 and K5 when dissolved in water. These methods have been applied to the determination of vitamin K5 as food preservative.This publication has 2 references indexed in Scilit:
