Abstract

The absolute stereostructures of panaxytriol (1) and panaxydol (2), two polyacetylenic constituents of the oriental medicine, Ginseng Radix Rubra, were determined by applying the modified Mosher method, CD exciton chirality method, and chemical conversion to be expressed as (3R, 9R, 10R)-heptadec-1-ene-4, 6-diyne-3, 9, 10-triol and (3R, 9R, 10S)-9, 10- epoxy-heptadec-1-ene-4, 6-diyn-3-ol, respectively. Panaxytriol (1), the characteristic ...
