Ameliorative effects of ginsenosides on myelosuppression induced by chemotherapy or radiotherapy.

Journal of Ethnopharmacology, 2020
BACKGROUND and ethnopharmacological relevance: As the major side effect of radiotherapy or chemotherapy, myelosuppression usually leads to anemia, hemorrhage, immunosuppression, and even fatal infections, which may discontinue the process of cancer ...

A novel neutral loss/product ion scan-incorporated integral approach for the untargeted characterization and comparison of the carboxyl-free ginsenosides from Panax ginseng, Panax quinquefolius, and Panax notoginseng.

Journal of Pharmaceutical and Biomedical Analysis, 2020
Differentiated composition in precursor ions for different subclasses of ginsenosides in the negative electrospray-ionization mode has been reported, which lays a foundation for the sorted and untargeted identification of ginsenosides.

Analysis methods of ginsenosides

Journal of Chromatography B, 2004
Ginsenosides are considered the main active principles of the famous Chinese traditional medicine "ginseng". For more than 30 years many researchers developed methods for the identification and quantification of ginsenosides in ginseng plant material, extracts and products.

Synthesis of Ocotillol-Type Ginsenosides

The Journal of Organic Chemistry, 2016
A total of 14 ocotillol-type ginsenosides were conveniently synthesized employing glycosylation of ocotillol sapogenin derivatives with glucosyl ortho-alkynylbenzoate donors under the promotion of a gold(I) catalyst as the key step. Relying on a rational protecting group strategy and the unexpected regioselectivity of the glycosylation of the 3,25-diol

Facile Synthesis of Ginsenoside Ro

Synlett, 2004
Two concise synthetic routes, being different in the glycosylation sequence, toward ginsenoside Ro (1) are developed. These syntheses feature the elaboration of the glucuronide residue at a later stage via the TEMPO-mediated selective oxidation and the installation of AZMB as a benzoylic neighboring participating group capable of being selectively ...
