RESUMO
Phytochemical studies on the leaves of Tripterygium wilfordii led to the isolation of seven new 18(4â¯ââ¯3)-abeo-abietane lactones, triptergulides E - K (1 - 7). The structure of the new compounds was elucidated on the basis of their spectroscopic analysis, and the absolute configurations of compounds were confirmed by ECD, calculated ECD, and X-ray crystallographic analysis using anomalous scattering of Cu Kα radiation. Some compounds showed moderate inhibitory activities against NO, IL-6, and TNF-α production in LPS RAW 264.7 macrophage in vitro.
