Panaxyne, A New Cytotoxic Polyyne from Panax ginseng Root against L1210 Cell

Abstract

A new polyyne, panaxyne, was isolated from the Korean red ginseng. The structure was determined as tetradeca-13-ene-1, 3-diyne-6, 7-diol by comparison of spectral data. The $ED_{50}\;value$ of panaxyne as cytotoxicity against L1210 cell was $11.0\;{\mu}g/ml$. The lower cytotoxic activity of the substance relative to other ginseng polyynes is presumably due to lack of the essential structural part of hept-1-en-4, 6-diyne-3-ol.
