Substance A, white prismatic crystal, mp $134{sim}135,;C_{29}H_{50}O$, substance B, white needle crystal, mp $131{sim}132^{circ},;C_{17}H_{28}O_4$ and substance C colorless oils, bp $84{sim}85,;C_{15}H_{24}O$ were isolated from the underground portion of Valeriana fauriei var. dasycarpa $H_{ARA}$(Valerianaceae) according to Thies method. Substance A was confirmed as known sterol, ${eta}-sitosterol$ by chemical and spectral discussions. Substance B was estimated as hitherto unknown sesquiterpenoid, 11-acetoxylhydroxyvaleranone by chemical and spectral discussions. Substance C was proposed as hitherto unknown sesquiterpenoid 1, 4-dimethyl-7-isopropenyl 4, 5, 6, 8, 9, 10-hexahydroazulene-1-ol by chemical and spectral discussions, and the general biogenetic considerations.
