A phytochemical investigation of the MeOH extract of Valeriana faurieiBriq. roots resulted in the isolation of two new sesquiterpenes, isovalerianin A (=(1β,4Z,6β,8α)‐8‐(acetyloxy)‐1,10‐dihydroxy‐6,11‐cyclogermacr‐4‐en‐15‐al=rel‐(1R,2Z,6S,7R,9R,10S)‐9‐(acetyloxy)‐6,7‐dihydroxy‐7,11,11‐trimethylbicyclo[8.1.0]undec‐2‐ene‐3‐carboxaldehyde; 1) and valerianin C (=(2α,3α,6α,8α)‐3‐(acetyloxy)‐2,4,8‐trihydroxyguai‐1(10)‐ene‐12,6‐lactone=...
Antidepressant activity-guided fractionation of the MeOH extract of Valeriana fauriei Briq. roots resulted in the isolation of two new germacrane-type sesquiterpenes (1–2) in addition to seven known ones (3–9). Their structures were elucidated as 1β,10α-dihydroxyl-8α-acetoxyl-10β,11,11-trimethyl-4-formyl-bicyclogermacren-E-4(5)-ene (1), 1β-hydroxyl-8α-acetoxyl-11,11-dimethyl-4-formyl-bicyclogermacren-E-4(5),10(14)-diene...
