Two new compounds, one flavanol dimer dapholosericol A ( 1 ) and one tigliane diterpene dapholosericin A ( 2 ), together with ten known ones, were isolated from the Ac OE t extract of Daphne holosericea ( Diels ) Hamaya . Their structures were elucidated by their spectroscopic data analysis. Compounds 1 and 2 showed moderate activities against acetylcholinesterase with inhibition ratio of 36% and 29% at a concentration of 100 μmol/l, respectively.
