[Abstract] Objective： To study chemical constituents from rhizome of Daphne papyracea var. crassiuscula. Method： Ethyl acetate fraction of 75% ethanol extracts from rhizome of D.papyracea var. crassiuscula，and its strucutre was identified by spectral method. Result： Nine compounds were separated and identified as daphneticin(1)，daphnetin(2)，hydrangetin(3)，daphnoretin(4)，1-4′-hydroxyphenyl-5-phenyl-2(E)-en-1-pentanone(5)，daphneolon(6)，3β-O-acetyl-olean-12-en(7)，and(+)-usnic acid(8). Conclusion： Compounds 1-8 were separated from D. papyracea var. crassiuscula for the first time. Compound 8 was separated from the genus for first time.
