Hypoglycemic constituents of Panax ginseng
General Pharmacology: The Vascular System, 1985This article reviews the recent progress in the identification of hypoglycemic and insulino-mimetic principles in ginseng. Hitherto five types of substances have been discovered. They include five glycans designated panaxans A to E, adenosine, a carboxylic acid, a peptide with a molecular weight of 1400 and lacking in basic amino acid residues, and a ...

Cryopreservation of Panax ginseng cells
Plant Cell Reports, 2000The impacts of cryoprotectants (CP) and cell status during the growth cycle on Panax ginseng cell viability during cryopreservation were investigated. The ginseng cells used had a 5-7 times proliferation rate (compared with inoculum) in 2-3 weeks and were subcultured at 2- and 4-week intervals in liquid and on solid media, respectively.

Dammarane saponins from Panax ginseng
Phytochemistry, 1995From the dried roots of Panax ginseng two new minor dammarane saponins named koryoginsenoside-R1 and -R2 were isolated, along with fourteen known saponins. On the basis of spectral and chemical evidence, the structure of the new saponins were elucidated as 6-O-[trans butenoyl-(1-->6)-beta-D-glucopyranosyl]-20-O-beta-D- glucopyranosyl dammar-24-en-3 ...

Genetic transformation is an attractive way to improve Panax ginseng C. A. Meyer by introducing new genetic materials and altering metabolic pathways that regulating the production of secondary compounds. In P. ginseng, production of transgenic plants via Agrobacterium tumefaciens is performed via somatic embryogenesis using cotyledon or embryogenic ...

American family physician, 2003
The herbal remedies referred to as "ginseng" are derived from the roots of several plants. One of the most commonly used and researched of the ginsengs is Panax ginseng, also called Asian or Korean ginseng. The main active components of Panax ginseng are ginsenosides, which have been shown to have a variety of beneficial effects, including anti ...

A ribonuclease from Chinese ginseng (Panax ginseng) flowers
Protein Expression and Purification, 2004A ribonuclease, with a molecular mass of 23kDa, and much higher activity toward poly(U) than poly(C) and only negligible activity toward poly(A) and poly(G), was isolated from the aqueous extract of Chinese ginseng (Panax ginseng) flowers. The ribonuclease was unadsorbed on diethylaminoethyl-cellulose and adsorbed on Affi-gel blue gel and carboxymethyl-

Genetic Transformation of Panax ginseng (Ginseng)
1999Ginseng (Panax ginseng C.A. Meyer) belongs to the Araliaceae family. In China and Korea, ginseng has been used medicinally for over 1000 years. Old literature recounts that ginseng cultivation in Korea began at least around 400 a.d. and in China around 40 b.c.

Pharmacokinetic Drug Interactions with Panax ginseng
European Journal of Drug Metabolism and Pharmacokinetics, 2016Panax ginseng is widely used as an adaptogen throughout the world. The major active constituents of P. ginseng are ginsenosides. Most naturally occurring ginsenosides are deglycosylated by colonic bacteria to intestinal metabolites. Ginsenosides along with these metabolites are widely accepted as being responsible for the pharmacologic activity and ...

Proteomic analysis of Korean ginseng (Panax ginseng C.A. Meyer)
Journal of Chromatography B, 2005Although many reports have been published regarding the pharmacological effects of ginseng, little is known about the biochemical pathways operant in ginsenoside biosynthesis, or the genes involved therein. Proteomics analysis is an approach to elucidate the physiological characteristics and biosynthetic pathways of ginsenosides, main components of ...
