Abstract Three new acetylated polyacetylenes named ginsenoynes F, G and H were isolated from the hexane extract of the roots of Panaxginseng . The structures were determinated by spectral and chemical methods.

Asymmetric synthesis of four possible stereoisomers of (9,10) -epoxyheptadecan-4,6-diyn-3-one was accomplished, and the absolute configuration of the naturally occurring (9R,10S)-epoxyheptadecan-4,6-diyn-3-one (1) was elucidated. (C) 2004 Elsevier Ltd. All rights reserved.
