Abstract
A new sesquiterpenoid lactone was isolated from terrestrial parts of A rtemisia subchrysolepis Filat. and studied by X-ray diffraction analys is and CD spectroscopy. This compound was called subchrysine and ident ified as -hydroxygermacra-4,10(14),11(13)-trien-12,6-olide. Pronounced temperature dependence of the H-1 and C-13 NMR spectra of subchrysine was observed. The results of conformational analysis of subchrysine b y quantum-chemical (PM3) and molecular mechanics (MMX) methods are als o presented.
