In vitro propagation of North American ginseng (Panax quinquefolius L.)

In Vitro Cellular & Developmental Biology - Plant, 2011
North American ginseng (NAG) (Panax quinquefolius L.) is a medicinally important plant with multiple uses in the natural health product industry. As seed propagation is time-consuming because of the slow growth cycle of the plant, in vitro propagation using a bioreactor system was evaluated as an effective approach to accelerate plant production.

Geographical origin of American ginseng (Panax quinquefolius L.) based on chemical composition combined with chemometric

Journal of Chromatography A, 2022
American ginseng (Panax quinquefolius L.) is protected by Geographical Indications as harvested roots have different regional characteristics. The aim of this study was to distinguish 95 American ginseng samples from four origins (including America, Canada, Shandong province and the Northeast provinces in China), and to further discriminate samples ...

DRYING OF NORTH AMERICAN GINSENG ROOTS (Panax quinquefolius L.)

Drying Technology, 1999
ABSTRACT The roots of North American ginseng (Panax quinquefolius L.) are dried from approximately 70% to less than 10% (wet basis), during which the roots may shrink up to 50% of their initial volume. Drying and shrinkage affect the physical quality of the dried root. Samples of fresh ginseng roots were dried and the root shrinkage was measured.

The relationship between genetic and chemotypic diversity in American ginseng (Panax quinquefolius L.)

Phytochemistry, 2013
Ginseng is one of the world's most important herbals used as an adaptogen and a cure for an impressively large range of ailments. Differences in the medicinal properties of ginseng roots have been attributed to variation in ginsenoside composition. In this study, the association between genetic and chemotypic profiles of wild and cultivated American ...

Ginsenoside content and variation among and within American ginseng (Panax quinquefolius L.) populations

Phytochemistry, 2006
The contents of five ginsenosides (Rg1, Re, Rb1, Rc and Rd) were measured in American ginseng roots collected from 10 populations grown in Maryland. Ginsenoside contents and compositions varied significantly among populations and protopanaxatriol (Rg1 and Re) ginsenosides were inversely correlated within root samples and among populations.

Ginseng (Panax quinquefolius L.) and goldenseal (Hydrastis canadensis L.) trials in eastern Kansas

Transactions of the Kansas Academy of Science, 2008
Abstract American ginseng and goldenseal, highly prized medicinal herbs found in the eastern United States, were planted over a period of years in eastern Kansas to test their viability as alternative crops. Ginseng has been reported to survive in the wild in eastern Kansas, but our trials have shown that it is difficult to establish artificially ...

Declining abundance of American ginseng (Panax quinquefolius L.) documented by herbarium specimens

Biological Conservation, 2007
American ginseng (Panax quinquefolius L.) is a native North American forest herb whose roots have been collected for their reputed medicinal properties and exported to international markets for nearly 300 years. Numerous anecdotal reports suggest declining abundance throughout its range, and the species is currently listed in Appendix II of the ...

Study on ginsenosides in different parts and ages of Panax quinquefolius L.

Food Chemistry, 2009
Abstract The contents of 12 ginsenosides (Rg1, Re, F11, Rf, Rg2, Rh1, Rb1, Rc, Rb2, Rb3, Rd, Rh2) in different parts and ages of Panax quinquefolius L. (American ginseng) were quantified by high pressure microwave-assisted extraction (HPMAE) high-performance liquid chromatography coupled with evaporative light scattering detection (HPLC-ELSD).

Transcriptomics and metabolomics reveal the changes induced by arbuscular mycorrhizal fungi in Panax quinquefolius L.

Journal of the Science of Food and Agriculture, 2023
AbstractBackgroundPanax quinquefolius L. is one of the most important foods and herbs because of its high nutritional value and medicinal potential. In our previous study we found that the ginsenoside content in P. quinquefolius was improved by arbuscular mycorrhizal fungi (AMFs).
