Metabolomic approach for discrimination of processed ginseng genus (Panax ginseng and Panax quinquefolius) using UPLC-QTOF MS
Discriminating between two herbal medicines (Panax ginseng and Panax quinquefolius), with similar chemical and physical properties but different therapeutic effects, is a very serious and difficult problem. Differentiation between two processed ginseng genera is even more difficult because the characteristics of their appearance are very similar. An ultraperformance liquid chromatography-quadru...
متن کاملGinsenoside contents in Panax quinquefolium organs from field cultivation.
Quantitative composition of saponins (ginsenosides) in Panax quinquefolium originating from field cultivation in Poland and harvested at the beginning of the growing season, during the blossoming period and at the end of growth was determined. A colourimetric method gave lower values compared to results of HPLC analysis, but the tendency of change in the content of saponins was similar in both ...
متن کاملEffects of Population and Age on Ginsenoside Content of American Ginseng (Panax quinquefolium L.)
American ginseng (Panax quinquefolium) is valued in traditional Asian medicine, and its use in Western countries has increased in recent years. The value of artificially-cultivated ginseng is much lower than that of woods-cultivated or wildcollected ginseng, but populations of the latter are threatened throughout its range. Our goal is to identify what factors influence the concentration of the...
متن کاملA new saponin from the leaves and stems of Panax quinquefolium L. collected in Canada.
A new dammarane-type saponin named quinquenoside L3 (1) together with vina-ginsenoside R3 (2) were isolated from the leaves and stems of Panax quinquefolium L. collected in Canada. On the basis of physicochemical and spectral evidences, 1 was established as 3-O-beta-D-glucopyranosyl-20-O-[beta-D-xylopyranosyl-(1-->6)-beta-D -glucopyranosyl] 20(S)-dammar-23-ene-3 beta, 12 beta,20,25-tetryol.
متن کاملSomatic Embryogenesis and Plantlet Regeneration from Hairy Roots Transformed by Agrobacterium rhizogenes in Panax quinquefolium L
Here, efficient plantlet regeneration via somatic embryogenesis from Panax quinquefolium hairy roots was reported. Callus development was optimal on MS medium containing 2,4-dichlorophenoxyacetic acid (1 mg l) and -naphthalene acetic acid (1 mg l). After a 4-week growth, calli were transferred onto MS medium with different combinations of plant growth regulators (PGRs). The highest embryogenesi...
