Picroside III is a cyclic enol ether terpene glycoside isolated from the traditional Chinese medicine hu huang lian.Picroside III has the potential to repair intestinal mucosal damage and reduce intestinal inflammation in mice.

6-Feruloylcatalpol is a cycloartenolide glycoside discovered in Callicarpa nudiflora, suitable for biochemical experiments and drug synthesis research.

Picroside IV is an iridoid glycoside originating from the underground parts of Picrorhiza scrophulariiflora and serves as a derivative of Catalpol while demonstrating broad pharmacological functions including neuroprotective, hypoglycemic, anti-inflammatory, anticancer, antispasmodic, antioxidant, and anti-HBV effects. Picroside IV therefore represents a therapeutically valuable bioactive molecule with high relevance in disease prevention and treatment research.
