Panax ginseng is one of the most important medicinal plants in Asia, particularly Korea. Triterpene saponins (ginsenosides) are the main bioactive compounds in P. ginseng. The present study investigates the growth characteristics and variation of ginsenoside content in the leaves and roots of Korean ginseng (Panax ginseng) at different growth stages (from 1 to 6 years). Variation in ginsenoside...

BACKGROUND Korean ginseng (Panax ginseng) is a well-known medicinal plant of Oriental medicine that is still in practice today. Until now, a total of 11 Korean ginseng cultivars with unique features to Korean ginseng have been developed based on the pure-line-selection method. Among them, a new cultivar namely G-1 with different agricultural traits related to yield and content of ginsenosides, ...

Ginseng is a traditional Chinese herb commonly used in the formulation of tonics. There are 2 main varieties: Oriental (Panax ginseng) and American ginsengs (Panax quinquefolius). Traditional means of authenticating ginseng have become less reliable since they are being processed into various formulations such as tablets, capsules, powder and tea. These products are sometimes also adulterated. ...

Panax vietnamensis was discovered recently in Vietnam. Its bamboo-like rhizomes, called Vietnamese Ginseng, have attracted considerable attention because of their specific pharmacological activities. In order to define the taxonomic position of this new species and include it in the molecular authentication of Ginseng drugs, the 18S ribosomal RNA gene and matK gene sequences of P. vietnamensis ...

This study was aimed (i) to develop an effective method for the purification of ginsenosides for industrial use and (ii) to compare the distribution of ginsenosides in cultured wild ginseng roots (adventitious root culture of Panax ginseng) with those of red ginseng (steamed ginseng) and white ginseng (air-dried ginseng). The crude extracts of cultured wild ginseng roots, red ginseng, and white...

Preparations of echinacea and ginseng likely comprise the most popular and commercially successful combination of medicinal plant products in North America. Interestingly, the development of Echinacea species for medicinal purposes stems from use by indigenous American people, but research has been conducted predominantly in Germany (Bauer and Wagner 1991). On the other hand, the reputation of ...

Asian ginseng is a perennial herb with a taproot resembling the shape of the human body. It grows in northern China, Korea, and Russia; its close relative, Panax quinquefolius, is cultivated in the United States. Because ginseng must be grown for 5 years before it is harvested, it commands a high price, with top-quality roots easily selling for more than $10,000. Dried, unprocessed ginseng root...

A total of 470 papers directly related to research on the Panax species were retrieved by performing internet searches with the keywords Panax and ginseng as the search terms. The publications were categorized as follows: 399 research articles, 30 reviews, 30 meeting abstracts, 7 proceedings, and 4 letters. The majority of these publications were published by scientists from Korea (35.7%), Chin...

Korean ginseng (Panax ginseng) and American ginseng (Panax quinquefolius) are widely used medicinal plants with similar morphology but different medicinal efficacy. Roots, flowers, and processed products of Korean and American ginseng can be difficult to differentiate from each other, leading to illegal trade in which one species is sold as the other. This study was carried out to develop conve...

Panax japonicus is an important medicinal plant. The aim of this study was to develop species-specific molecular markers for P. japonicus. Amplified fragment length polymorphism (AFLP) was compared among P. japonicus, P. ginseng and P. quinquefolius. A clear species-specific AFLP marker for P. japonicus was generated. After isolation and sequencing of the AFLP fragment, a DNA sequence (293 bp) ...
