An optimized microwave-assisted extraction method for increasing yields of rare ginsenosides from Panax quinquefolius L.
BACKGROUND Rare ginsenosides in Panax quinquefolius L. have strong bioactivities. The fact that it is hard to obtain large amounts of rare ginsenosides seriously restricts further research on these compounds. An easy, fast, and efficient method to obtain different kinds of rare ginsenosides simultaneously and to quantify each one precisely is urgently needed. METHODS Microwave-assisted extrac...
متن کاملSimplified extraction of ginsenosides from American ginseng (Panax quinquefolius L.) for high-performance liquid chromatography-ultraviolet analysis.
Four methods were tested for extraction and recovery of six major ginsenosides (Rb1, Rb2, Rc, Rd, Re, and Rg1) found in roots of American ginseng (Panax quinquefolius): method A, sonication in 100% methanol (MeOH) at room temperature (rt); method B, sonication in 70% aqueous MeOH at rt; method C, water extraction (90 degrees C) with gentle agitation; and method D, refluxing (60 degrees C) in 10...
متن کاملGinsenosides Derived from Asian (Panax ginseng), American Ginseng (Panax quinquefolius) and Potential Cytoactivity
Ginseng is a slow-growing, deciduous perennial plant that belongs to the Araliaceae family and the Panax genus. There are a variety of species but the two main types are Panax ginseng C.A Meyer (Asian ginseng) and Panax quinquefolius (American ginseng). Asian ginseng is further subdivided by drying method of the root into either red or white ginseng. Traditionally, both Asian and American ginse...

15 صفحه اولInvestigation of ginsenosides in different tissues after elicitor treatment in Panax ginseng
BACKGROUND The effect of methyl jasmonate (MJ) on ginsenoside production in different organs of ginseng (Panax ginseng Meyer) was evaluated after the whole plant was dipped in an MJ-containing solution. MJ can induce the production of antioxidant defense genes and secondary metabolites in plants. In ginseng, MJ treatment in adventitious root resulted in the increase of dammarenediol synthase ex...
