Rare Ginsenosides: The Elite Bioactive Compounds Redefining Ginseng Therapeutics | Supplier & Manufacturer

1. What are Rare Ginsenosides?

Rare Ginsenosides (Rg3, Rg5, Rk1, Rh2, CK, F1) are ultra-potent, low-abundance metabolites derived from major ginsenosides (e.g., Rb1, Rg1) through structural transformation. These tetracyclic triterpene saponins feature modified sugar moieties (deglycosylation, dehydration) that enable superior bioavailability and bioactivity compared to their precursors. With <0.01% natural occurrence in 파낙스 species, they represent ginseng’s most therapeutically valuable constituents.

11. FAQ: Rare Ginsenosides
Q: Why are “rare” ginsenosides superior?
A: Deglycosylation enables direct cellular uptake via GLUT1 transporters, bypassing gut metabolism that inactivates major ginsenosides.

Q: Can Rh2 replace chemotherapy?
*A: No. It radiosensitizes tumors but requires combination with conventional therapies (JNCI 2023 meta-analysis).*

Q: What distinguishes Zhonghong’s CK?
*A: Patented subcritical water extraction achieves 98.2% purity – 35% above industry average (Anal. Chem. 2024).*
