Treatment of rats with a single oral dose (10–30 mg/kg) of a crude Panax ginseng extract of unknown ginsenoside content has been reported to modestly increase hepatic microsomal cytochrome P450-mediated aminopyrine N-demethylation activity. In the present study, we compared the effect of P. ginseng and Panax quinquefolius extracts on rat hepatic CYP2B1, CYP3A23, and CYP1A2 gene expression. Adul...

High hydrostatic pressure (HHP) is an attractive method for food preservation due to resulting improvements in the quality characteristics of foods, in addition to microbial inactivation. This study aimed at improving the nutraceutical potential of red ginseng (Panax ginseng C.A. Meyer). HHP treatment of 600 MPa for 1 min at room temperature in conjunction with conventional steaming and drying ...

aceae), has been heat-processed to improve its medicinal efficacies in Korea based on the long history of ethnopharmacological evidence. Although the increasing body of evidence supports that Maillard reaction products (MRPs) are implicated in the increased activity by heat treatment in various crude drugs or foods, the effect of Maillard reaction on the active components of ginseng and biologi...

AimsThere is an increasing awareness of the importance root-associated bacteria and fungi to plant growth. At present, little known about whether different ginseng cultivars affect soil rhizosphere microbial community. Here, we examined changes in microorganismal diversity composition rhizospheres cultivars.MethodsThe four cultivars, namely CBGL (GAOLI ginseng), JYSH (COMMON ginseng) SZSZ (SHIZ...

BACKGROUND DNA in herbal decoctions is usually fragmented by extensive boiling and is usually regarded as unsuitable for molecular authentication. This study aims to evaluate the feasibility for molecular authentication methods by multiplex polymerase chain reaction (PCR) and DNA sequencing for decoctions. METHODS The DNA extraction procedure, sample pulverization and boiling time were examin...
