Loganin

The signature compound of Cornus fruit and its quality marker compound

Loganin is an iridoid glycoside in which glucose is attached to a cyclopenta[c]pyran skeleton, and it is the signature compound of Cornus fruit. In plants, it is formed by methylation of loganic acid and sits at a waypoint leading, through secologanin, to the biosynthesis of monoterpene indole alkaloids.

The Korean Pharmacopoeia sets a combined loganin and morroniside content of at least 1.2% as the quality standard for Cornus. In cell and mouse studies, suppressed expression of adipocyte differentiation genes (PPARγ, C/EBPα, and others) has been reported.

CategoryIridoid glycoside
OriginFruit of Cornus (Cornus officinalis)
RoleMarker compound (quality standard) of the Cornus ingredient
BiosynthesisLoganic acid → loganin → secologanin → strictosidine
Level of researchCell and mouse studies; human studies were done on the complex ingredient as a whole

The Cornus extract complex, which is managed using loganin as a marker compound, has been commercialised by partner company ONDAM BIO as the consumer product “SANBIDAM Premium.”
