Investigation of ginsenosides in different parts and ages of Panax ginseng

Field Cultivation and in vitro Cultures, Root-Forming Callus Cultures and Adventitious Root Cultures, of Panax quinquefolium as a Source of Ginsenosides

“…Chung et al (2012) reported the absence of ginsenoside Rc from the roots of the P. ginseng variety "Jankyung" growing in three locations in Korea. These results are also in contrast to the observations of Shi et al (2007) and Corthourt et al (1999). These differences might be due to a multiplicity of factors related to genetic or enviromental determinants (temperature, soil conditions, light intensity, root microfl ora), the ginseng cultivar, and processing conditions (Chung et al, 2012;Du et al, 2004).…”

“…The total content of the six examined ginsenosides was highest in the root hairs (128 mg/g dw) and lowest in the main roots. Previous studies (Qu et al, 2009;Shi et al, 2007) yielded similar results for 5-year-old roots of P. quinquefolium and P. ginseng, but the roots examined in those studies had a lower content of ginsenosides, i.e. about 70 and 86 mg/g dw, respectively.…”

Cosmetic Potential of Enzymatic Treated Ginseng Leaf

“…Traditionally, ginseng leaf has been consumed mostly in the form of tea. Ginseng leaf is rich in polysaccharides, polyphenols, and flavonoids [8][9][10], and contents of some ginsenosides are higher than in the roots [11]. However, these compounds are tightly linked with carbohydrates such cellulose, pectin, or β-glucan.…”

“…In addition, groups of scientists have found that ginseng leaves are rich in polysaccharides, polyphenol, flavonoids, and ginsenosides [8][9][10]. Shi et al [11] reported that the content of ginsenoside Re in P. ginseng leaves and roothairs is about five times higher than that of Rg1, but Re content is lower than that of Rg1 in the root. They also suggested that P. ginseng leaf may be more beneficial than other plant parts.…”

Effect of Black Ginseng on Memory Improvement in the Amnesic Mice Induced by Scopolamine

“…Saponin determination was analyzed as described by Shi et al [10], with the following modifications. To extract saponin, 1 g of white ginseng, red ginseng, or black ginseng was added to 20 ml of 20% ethanol and ultrasonicated three times at 50 o C for 1 hr (60 kHz, heat power 330 W).…”
