Analytical Chemistry, 1999
An HPLC/MS/MS method has been developed for the characterization and quantification of ginsenosides contained in extracts of the root of Panax ginseng (Korean ginsengs) and Panax quinquefolius L. (American ginsengs). The [M + H]+ and [M + Na]+ ions were observed for ginsenoside standards (Rb1, Rb2, Rc, Rd, Re, Rf, Rg1) and four different ginseng ...

Forest Ecology and Management, 2013
Abstract The light environment of the forest understory is heterogeneous, characterized by low levels of diffuse light punctuated by short periods of direct solar radiation known as sunflecks. Less well understood is the degree to which sunflecks are responsible for spatially varying performance of understory plants.

The Neglected Ginsenosides of North American Ginseng (Panax quinquefoliusL.)
Journal of Herbs, Spices & Medicinal Plants, 2000ABSTRACT The high performance liquid chromatographic (HPLC) procedures commonly employed for the assay of ginsenosides in Panax quinquefolius L. (North American Ginseng) neglect assessment of acidic, mainly malonyl, ginsenosides. As such, total ginsenoside values for this species, in contrast with corresponding values for Panax ginseng C.A.

Abstract Goldenseal (Hydrastis canadensis L.) and American ginseng(Panax quinquefolius L.) have been harvested commercially for the past few centuries. Harvested populations can recover if vegetative propagules remain in the soil. Experiment I tested the efficacy of vegetative reproduction in goldenseal and ginseng.

Historical climate change caused shifts in species’ distributions in eastern North America. Pleistocene glaciations shrunk ranges into refugia, from where they later spread northward following recession of the ice. I analyzed the post-glacial history of the declining native medicinal forest understory plant American ginseng (Panax quinquefolius L ...

AbstractImproving the cultivation mode and technology for traditional Chinese medicine has become important for its sustainable development. Monoculture enhances plant diseases, which decreases yield and quality. Intercropping is an effective measure to counterbalance that negative effect. In this study, we focused on Panax quinquefolium L.
