Hydnocarpus anthelminthica

Cyclopentenyl)-9-tridecenoic acid C,8H3o02 M 278.434 Isol. from Caloncoba echinata, Hydnocarpus anthelminthica and H. wightiana seeds. Probably opt. active and with (Z)-config. 

The nonprotein amino acid cyclopentenylglycine (45) is a constituent of the ffee-amino-acid pool in seeds and leaves of Hydnocarpus anthelminthica and Caloncoba echinata (Flacourtiaceae), where it comprises up to 2% of the total free amino acids. This unusual compound is derived via the pathway presented in Fig. 2.18. This amino acid is then converted to cyclopentenylcarboxylic acid (aleprolic acid) (46)...
