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

摘要

The content of six ginsenosides (Rb1, Rb2, Rc, Rd, Rg1, and Re) was studied in the roots of fi eld-grown plants, as well as in root-forming callus cultures and adventitious root cultures of Panax quinquefolium using high-performance liquid chromatography (HPLC). The highest level of saponins was isolated from root hairs (128 mg/g dry weight). The examined in vitro culture synthesized all identifi ed saponins, although in smaller amounts than those obtained from fi eld cultivation. Metabolites Rb1 and Re dominated in the ginseng biomass from both fi eld crops and in vitro culture.
