Gypenoside UL4-Rich Gynostemma pentaphyllum Extract Exerts a Hepatoprotective Effect on Diet-Induced Nonalcoholic Fatty Liver Disease.

Nonalcoholic steatohepatitis (NASH) arises from nonalcoholic fatty liver disease (NAFLD) as a consequence of oxidative stress. Gynostemma pentaphyllum extract (GPE) is proven to be beneficial for patients suffering from NAFLD. However, the precise mechanism by which GPE confers these benefits remains largely unknown.

The therapeutic effect of tissue cultured root of wild Panax ginseng C.A. Mayer on spermatogenetic disorder.

This study examined the possibility of using a tissue cultured root of wild Panax ginseng (tcwPG) as a fertility agent. The effect of tcwPG on spermatogenesis was studied using male rats. The tcwPG crude powder was administered orally to 7-week-old rats over a 6-week period.

Effect of oxygen supply on cell growth and saponin production in bioreactor cultures of Panax ginseng.

The effects of oxygen supply within the range 20.8-50% (using pure oxygen and air), on cell cultures of Panax ginseng were investigated in a balloon-type bubble bioreactor (5L capacity, containing 4 L Murashige and Skoog medium, supplemented with 7.0 mgL(-1) indolebutyric acid, 0.

Methyl jasmonate and salicylic acid elicitation induces ginsenosides accumulation, enzymatic and non-enzymatic antioxidant in suspension culture Panax ginseng roots in bioreactors.

The effects of methyl jasmonate (MJ) and salicylic acid (SA) on changes of the activities of major antioxidant enzymes, superoxide anion accumulation (O2-), ascorbate, total glutathione (TG), malondialdehyde (MDA) content and ginsenoside accumulation were investigated in ginseng roots (Panax ginseng L.) in 4 l (working volume) air lift bioreactors. Single treatment of 200 microM MJ and SA to P.
