review through recovery, purification and identification of genipin

Genipin is a secoiridoid that may be obtained directly from Genipa americana and after geniposide hydrolysis from Gardenia jasminoides fruits. It is well known that genipin is a high added value product which has a great potential for its application in different fields, such as medicine and food industry. A lack of information and research about the development of novel methods for the environmental friendly recovery and purification of genipin exists, focused on the green recovery of genipin through emerging technologies that lead to the sustainable extraction. In the present review, the available methods for recovery of genipin and geniposide are enlisted and described, as well as the reaction mechanism of genipin, and the developed methods for genipin and geniposide identification and quantification based on HPLC analysis. Moreover, this work reveals the scarcity of available identification methods for genipin, that should be taken into account to fulfill the recovery and quantification process of genipin.
