Chantriolides F-P, Highly Oxidized Withanolides with Hepatoprotective Activity from .

Eleven highly oxidized withanolides, chantriolides F-P (-), together with six known analogues (-), were isolated from the rhizomes of . Their structures were established on the basis of comprehensive spectroscopic data analysis and comparison with published NMR data, and their absolute configurations were further confirmed by experimental ECD data and single crystal X-ray diffraction analysis. The structures of compounds - contained a chlorine atom substituted at C-3.
