The present invention relates to a composition comprising an extract of
Anemarrhena asphodeloides
Bunge or the compounds isolated from the same, as an active ingredient. In particular, the extract and compounds have the excellent inhibitory effects on adipocyte differentiation, and thus can be used in a pharmaceutical composition and functional food for the prevention and treatment of lipid metabolism disorders.

were correlated with the dihedral angles between Pd and endo-β-H. This correlation revealed that in the case of the six-membered lactone an energetically favorable conformer adopts a nearly synperiplanar Pd/endo-β-H arrangement, whereas for the analogous Pd σ-complex of the five-membered lactone the smallest Pd/endo-β-H dihedral angle is observed for a conformer with a comparatively high potential energy
