GRAPHICAL ABSTRACT
ABSTRACT
Bioassay-guided led to the isolation of five compounds, including a new picrotoxane-type sesquiterpene lactone, aduncin C (1), together with four known ones (2-5) from Dendrobium huoshanense. Their structures were elucidated by means of extensive spectroscopic analysis. Biological evaluation of the isolates against four human cancer cell lines indicated broad-spectrum and cytotoxic activities with IC50 values ranging from 4.08 to 26.75 μM. Among them, α-dihydropicrotoxinin (3) exhibited significant cell proliferation inhibitory activity, especially for HL-60 (IC50 5.81 μM), MCF- 7 (IC50 6.49 μM), SW-480 (IC50 6.80 μM), respectively.
