Ginsenoside Rh4, a genuine dammarane glycoside from Korean red ginseng
TL;DR: A genuine glycoside, named ginsenoside Rh4, was isolated from Korean red ginseng through repeated column chromatography, and its chemical structure was established to be 6-O-beta-D-glucopyranosyldammar-20(22),24-diene-3 beta,6 alpha,12 beta-triol by spectral and chemical methods.
Journal ArticleDOI
In Vitro and In Vivo Antitumoral Phenanthrenes from the Aerial Parts of Dendrobium nobile
TL;DR: Two phenanthrenes were isolated from the aerial part of Dendrobium nobile Lindl and were found to be cytotoxic against A549, SK-OV-3, and HL-60 cell lines and antitumor activity on the life span of ICR mice intraperitoneally implanted with 1 x 10(6) cells of sarcoma 180.

TL;DR: A genuine dammarane-glycoside, named as ginsenoside Rs3, was isolated from the MeOH extracts of Korean red ginseng through repeated silica gel column chromatographies and its chemical structure was determined as (20S)-protopanaxadiol 3-O-[6″-O-acetyl-β-D-glucopyranosyl (1→2)-β- D- glucopyrside.
Journal ArticleDOI
Cytotoxicities of ginseng saponins and their degradation products against some cancer cell lines
TL;DR: Diol-type prosapogenins and sapogenins showed higher cytotoxicity than triol-type ones, and the activity was inversely proportional to the number of sugars linked to saponins.
Journal ArticleDOI
Ginsenoside Rf2, a new dammarane glycoside from Korean red ginseng (Panax ginseng)
TL;DR: A new dammarane glycoside named ginsenoside Rf2 has been isolated from Korean red ginseng and its chemical structure has been elucidated as 6-O-[α-L-rhamnopyranosyl (1→2) β-D-glucopyranoyl]dammarane-3β, 6α, 12β, 20(R), 25-pentol by chemical and spectral methods.
