Identification
Biological Activities
Compounds
Catalpa is a genus of trees that serves as a unique source for specific chemical compounds. Within this genus, the glycoside known as catalposide can be found occurring naturally. This particular substance is identified as the p-hydroxybenzoyl ester of catalpol. While catalpol is found in free states in other species like Plantago, it exists in this esterified form within Catalpa. Understanding these specific plant relationships is essential for the accurate chemical classification of these glycosides.
