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 -1">50 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, and as the intermediate for alkaloid syntheses.[2]
The blue color of genipin is stabilized in milk due to the natural pH of milk [3]
In vitro experiments have shown that genipin blocks the action of the transporter uncoupling protein 2.[4]
