Uncarine E

Isopteropodine (CAS 5171-37-9), also known as uncarine E or 7-isopteropodine, is a naturally occurring oxindole alkaloid primarily isolated from Uncaria tomentosa (Cat’s claw) and related Uncaria species. It belongs to the group of tetracyclic oxindole alkaloids that contribute to the characteristic phytochemical profile of this traditional medicinal plant.

Isopteropodine and other oxindole alkaloids from Cat’s claw have been studied for their potential immunomodulatory, anti-inflammatory, antimicrobial, and cytotoxic properties in preclinical research. As a key marker compound, isopteropodine serves as an important analytical reference standard for the standardization and quality control of Cat’s claw extracts, herbal medicines, and dietary supplements. High-purity isopteropodine enables accurate quantification and method validation in laboratories analyzing Uncaria products.

Planta Analytica provides high-purity isopteropodine as an analytical reference standard to support precise analysis, research applications, and extract standardization in laboratories worldwide.

The list of the most common alkaloids standards isolated from Cat’s claw includes: isorhynchophylline, isomitraphylline, rhyncophylline, mitraphylline, isoorientin, uncarine D, uncarine E, uncarine C, and uncarine F. Find the entire collection of uncaria alkaloids here.
