Genipin is a chemical compound found in Genipa americana fruit extract. It is an aglycone derived from an iridoid glycoside called geniposide which is also present in fruit of Gardenia jasminoides . ^[1]

Genipin is an excellent natural cross-linker for proteins, collagen, gelatin, and chitosan cross-linking. It has a low acute toxicity, with LD₅₀ i.v. 382 mg/kg in mice, therefore, much less toxic than glutaraldehyde and many other commonly used synthetic cross-linking reagents. Furthermore, genipin can be used as a regulating agent for drug delivery, as the raw material for gardenia blue pigment preparation ^[2] , and as the intermediate for alkaloid syntheses. ^[3]

In vitro experiments have shown that genipin blocks the action of the transporter uncoupling protein 2. ^[4]
