Their structures were fully characterized by spectral methods. The cytotoxicity of these compounds against then MGC80-3 human gastric cancer cell line was also assessed. High inhibitory effects were found at a concentration of 100 ¦Ìg/mL. %K ginsenoside %K synthesis %K cytotoxicity %K MGC80-3 %U http://www.mdpi.com/1420-3049/18/4/3689
