The herbal products baicalin, baicalein, chlorogenic acid, and ginsenoside Rf have multiple pharmacological effects and are extensively used in alternative and/or complementary therapies. The present study investigated whether baicalin, baicalein, chlorogenic acid, and ginsenoside Rf induced the expression of the

In the present study, we have examined any possible involvement of L-type Ca(2+) channels in ginseng-mediated neuroprotective actions. Exposure to a 50mM KCl (high-K) produced neuronal cell death, which was blocked by a selective L-type Ca(2+) channel blocker in cultured
Lei Liu et al.
Bioscience, biotechnology, and biochemistry, 74(1), 96-100 (2010-01-09)
In this study, rare ginsenoside Rf was transformed into 20(S)-protopanaxatriol (PPT(S)) by glycosidase from Aspergillus niger. By investing the reaction conditions, the optimal conditions were obtained, as follows: pH 5.0, temperature 55 degrees C, and substrate concentration 1.25 mmol/l. Under

Because little is known about the interactions between herbal products and standard medications, the effects of seven ginsenosides and two eleutherosides (active components of the ginseng root) on the catalytic activity of c-DNA expressed cytochrome P450 isoforms were studied in
Eun-Ah Bae et al.
Biological & pharmaceutical bulletin, 29(9), 1862-1867 (2006-09-02)
The inhibitory effects of the Korean red ginseng (steamed root of Panax ginseng C.A. MEYER, family Araliaceae) saponin fraction (KRGS) and its constituents ginsenosides Rg3, Rf, and Rh2 in mouse passive cutaneous anaphylaxis (PCA) and contact dermatitis models were measured.

We investigated whether ginseng regulates lipoprotein metabolism by altering peroxisome proliferator-activated receptor alpha (PPARalpha)-mediated pathways, using a PPARalpha-null mouse model. Administration of ginseng extract, ginsenosides, and ginsenoside Rf (Rf) to wild-type mice not only significantly increased basal levels of hepatic
