Background: The biological activity and pharmacological effects of rare ginsenosides have been proven to be superior to those of the major ginsenosides, but they are rarely found in ginseng.
Methods: Ginsenoside Rb1 was chemically transformed with the involvement of methanol molecules by a synthesized heterogeneous catalyst 12-HPW@MeSi, which was obtained by the immobilization of 12-phosphotungstic acid on a mesoporous silica framework. High-performance liquid chromatography coupled with mass spectrometry was used to identify the transformation products.
Article Synopsis
- Scientists found that rare ginsenosides, which are important for health, are not easily found in regular ginseng and need to be made using chemical changes.
- They used a special catalyst and ethanol to change ginsenoside Rb1, creating 16 new products that were identified using advanced scientific tools.
- The process can be used multiple times, helping to create these rare ginsenosides effectively while recycling materials, making it both efficient and eco-friendly.
DC. and Willd. have different clinical efficacies, with the former typically used to treat typhoid fever and the latter mainly used to clear liver heat.
