Enzymatic preparation of genuine prosapogenin, 20(S)-ginsenoside Rh1, from ginsenosides Re and Rg1
It was found that a lactase preparation from Penicillium sp. nearly quantitatively hydrolyzed ginsenosides Re and Rg 1 , which are major saponins in roots of Panax ginseng, to a minor saponin, 20(S)-ginsenoside Rh 1 [6-O-β-D-glucopyranosyl-20(S)-protopanaxatriol]. This is the first report on the enz...
