Abstract: Air drying (AD), freeze‐drying (FD), and vacuum‐microwave drying (VMD) were applied to fresh North American ginseng roots to evaluate the effect of different drying techniques on pore characteristics and the subsequent recovery of ginsenoside content. FD ginseng root produced the lowest reductions in both total moisture content and water activity (P < 0.05), with no differences noted...
Rg3 and Rh2 ginsenosides are primarily found in Korean red ginseng root (Panax ginseng C.A. Meyer) and valued for their bioactive properties. We quantified both Rh2 and Rg3 ginseng leaf and Rg3 from root extracts derived from North American ginseng (Panax quinquefolius). Quantification was obtained by application of HPLC with ion fragments detected using ESI-MS. Ginseng leaf contained 11.3±0.5 mg/g...
