A pilot-scale culture of multiple adventitious roots of ginseng was established using a balloon-type bubble bioreactor. Adventitious roots (2 cm) induced from callus were cultured in plastic Petri dishes having 20 ml of solid Schenk and Hildebrandt (1972) medium containing 3% sucrose, 0.15% gelrite, and 24.6 μM indole-3-butric acid. An average of 29(More)
A new method of high-performance liquid chromatography coupled with evaporative light scattering detection (HPLC-ELSD) was developed for the simultaneous quantification of 14 major ginsenosides, which are the marker compounds of Panax ginseng C.A. Meyer (Korean red ginseng). Various types of ginseng samples were extracted, and the amounts of the 14(More)
Ginseng (Panax ginseng C. A. Meyer) has been well known to have a variety of ginsenosides that show diverse biological activities. Especially, the components of ginsenosides are quite different depending on the processing method. Recently, there have been several reports showing that less polar ginsenosides from Korean red ginseng (steam-treated Panax(More)
Ginseng, the root of Panax ginseng C. A. MEYER, has been used as a food product and medicinal ingredient. In this study, we assessed the anti-arthritic effects of red ginseng saponin extract (RGSE), including ginsenosides Rg3, Rk1 and Rg5 as major components, on a murine type II collagen (CII)-induced arthritis (CIA), which is a valid animal model of human(More)
Protoplasts were isolated from leaf mesophyll of hybrid poplar (Populus nigra X P. maximowiczii) with a mean yield of 10.4 x 106 protoplasts per g fresh weight using 2.0% Cellulase ‘Onozuka’ R-10, 0.8% Macerozyme R-10, 1.2% Hemicellulase, 2.0% Driselase, and 0.05% Pectolyase Y-23 with CPW salts solution containing 0.6 M mannitol, 0.002 M DTT, 3 mM MES at pH(More)
Friable calli derived from the stem tissues of Populus alba were used to establish cell suspension cultures which were characterized for in vitro growth and regeneration capacity. Suspended cells and callus recovered from these cells were maximal on a fresh weight basis using MS liquid medium containing 0.44 μM BAP and 4.52 μM 2,4-D. Shoot regeneration from(More)
 A novel type of bioreactor was successfully developed for the production of taxol and its precursors by culturing cells of Taxus cuspidata (Japanese yew) on a pilot-scale. Rapidly growing cell lines were selected from callus cultures derived from immature embryos of yew. The cells were inoculated in 20-l capacity bioreactors of different types to test the(More)
Ginseng, the root of Panax ginseng C. A. Meyer, is frequently used in traditional oriental medicines. The major active components of ginseng are the saponins, which are also called ginsenosides and are known for their pharmacological and biological activities. In this study, the effects of ginsenosides on lipid accumulation in 3T3-L1 adipocytes were(More)
Various explant sources of Populus nigra × P. maximowiczii were used to examine the effects of growth hormones on morphogenesis in vitro. Initial experiments indicated that punctured leaves were superior to non-punctured ones for both callus growth and formation of shoots and roots on MS medium containing various types and concentrations of growth hormones.(More)
Expiants for establishing callus cultures originated from in vitro cultured hybrid poplar (Populus alba L. X P. grandidentata Michx.). Plant regeneration was achieved from established callus cultures derived from stem internodes (SI), leaf discs (LD), and root segments (RS). Shoot regeneration from callus occurred within 4 weeks of culture on most of the(More)
