摘要与影响
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 AcOEt 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.
