Five new α-pyrone derivatives, cryptoyunnanes A - E (-), together with four known analogues, were isolated from the leaves and twigs of . Their structures including absolute configurations were elucidated by extensive spectroscopic data and electronic circular dichroism (ECD) analyses. Compounds and showed significant cytotoxicity against A549, HCT-116, MDA-MB-231, PC-3 and HeLa with IC values from 2.25 to 8.97 M. Compounds , and also displayed good cytotoxicity against HCT-116, MDA-MB-231 and PC-3 with IC values from 1.26 to 8.32 M. This is the first time to report the isolation and bioactivity evaluation of chemical constituents from .
