Abstract

The roots of Alkanna orientalis (L.) Boiss yielded alpha-methyl-n-butyl alkannin (compound 1) and alkannin acetate (compound 2). The compounds were identified by UV, MS, (1)H NMR and (13)C NMR. Quantitative determination of alpha-methyl-n-butyl alkannin and alkannin acetate in Alkanna orientalis (L) Boiss roots was established by TLC densitometry.

Keywords: Alkanna orientalis; NMR; TLC densitometry; alkannin acetate; naphthaquinones; α- methyl-n-butyl alkannin.
