Description:
A phytochemical investigation of the MeOH extract of Valeriana fauriei Briq . roots resulted in the isolation of two new sesquiterpenes, isovalerianin A (=(1 β ,4 Z ,6 β ,8 α )-8-(acetyloxy)-1,10-dihydroxy-6,11-cyclogermacr-4-en-15-al= rel -(1 R ,2 Z ,6 S ,7 R ,9 R ,10 S )-9-(acetyloxy)-6,7-dihydroxy-7,11,11-trimethylbicyclo[8.1.0]undec-2-ene-3-carboxaldehyde; 1 ) and valerianin C (=(2 α ,3 α ,6 α ,8 α )-3-(acetyloxy)-2,4,8-trihydroxyguai-1(10)-ene-12,6-lactone= rel -(3 R ,3a S ,4 R ,7 S ,8 S ,9 R ,9a R ,9b R )-8-(acetyloxy)-3a,4,5,7,8,9,9a,9b- octahydro-4,7,9-trihydroxy-3,6,9-trimethylazuleno[4,5- b ]furan-2(3 H )-one; 2 ), together with six known compounds, i.e. , camphor, methyl 4-hydroxybenzoate, 2-methoxybenzoic acid, benzoic acid, quercetin, and kaempferol. The structures of the compounds were established by detailed spectral analysis and comparison with previously reported data.
