Supercritical CO2 Extraction and Identification of Ginsenosides in Russian and North Korean Ginseng by HPLC with Tandem Mass Spectrometry

Ginseng roots, Panax ginseng C.A. Meyer, obtained from cultivated ginseng grown in the Kaesong province (North Korea) and Primorye (Russia) were extracted using the supercritical CO₂ extraction method. The extracts were subsequently analyzed by high-performance liquid chromatography with tandem mass spectrometry identification. The results showed the spectral peaks of typical ginsenosides with some other minor groups, and major differences were observed between the spectra of the two ginseng samples. The use of a pressure of 400 bar and higher allowed an increase in the yield of ginsenosides in comparison with similar previous studies

Effect of Phytoadaptogen Administration during Early Ontogeny on Lifespan and Somatic Status of CBA Mice with High Incidence of Tumors

We studied the influence of nontoxic phytoadaptogen complex on the lifespan and somatic status (body weight, coat state, and motor activity) of CBA mice predisposed to spontaneous hepatomas. Administration of the complex phytoadaptogen during the first month of postnatal ontogeny increased mean animal lifespan by 17.1% (p<0.001) and median of survival by 25.6% (p<0.001) and promoted maintenance of satisfactory physical status of CBA mice during spontaneous hepatocarcinogenesis.
