"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 (2), bicyclo[8,1,0]5β-hydroxyl-7β-1acetoxyl-5α,11,11′-trimethyl -E-1(10)-ene-4α,15-olide (3), 8α-acetoxyl-3α,4α,10-trihydroxyl-guaia-1(2)-ene-12,6α-olide (4), 2-Ethylhexyl-4-hydroxybenzoate (5), 11αH-gemacra-1(10)E,4Z-diene-3-one-12,6α-olide (6), β-Sitoterol (7), isovaleric acid (8), isoborneol acetate (9), using a combination of UV, IR, mass spectroscopy, 1D and 2D NMR spectroscopy. The antidepressant activity of compounds 1–4 was investigated by the FST on mice. Among them, compounds 3 and 4 showed the significant antidepressant activity (*, P < 0.01)." \\ | "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).
