Phytochemical studies on the underground parts of Asperula taurina subsp caucasica
One naphthohydroquinone (mollugin) (1), 3 anthraquinones (1-hydroxy-2-methyl-9,10-anthraqinone (2), 1,3-dihydroxy-2-methoxymethyl-9,10-anthraquinone (4) and 1,3-dihydroxy-2-carboxy-9,10-anthraquinone (7, munjistin)), beta-sitosterol (3), 1 naphthalene glycoside (2-carbomethoxy-3-prenyl-1,4-naphthohydroquinone, 1,4-di-O-beta-glucoside (5)) and I anthraquinone glycoside (lucidin-3-O-beta-primeveroside (6)) were isolated from the underground parts of A. taurina subsp. caucasica. The structures of the isolates were established by MS, H-1-NMR and C-13-NMR analysis.
