C13-Norisoprenoids in the Aroma of Colombian Tropical Fruits

Abstract:

This chapter focuses on the identification of C13-norisoprenoid volatile compounds in free and glycosidically bound forms in lulo (Solanum quitoense), lulo del Chocó (Solanum topiro) and mammee apple (Mammea americana). Thirteen C13-norisoprenoids were identified in lulo plant (pulp and peelings of the fruit, flowers and leaves) in free and bound forms. Furthermore, by chromatographic and spectroscopic means we could identify in lulo leaves the new compound (6R,9R)-13-hydroxy-3-oxo-α-ionol 9-O-β-D-glucopyranoside, the known (3S,5R,8R)-3,5-dihydroxy-6,7-megastigmadien-9-one 5-O-β-D-glucopyranoside, (6S,9R) vomifoliol 9-O-β-D-glucopyranoside, (3S)-3-hydroxy-5,6-epoxy-β-ionol 9-O-β-D-glucopyranoside and (6R,9R)-3-oxo-α-ionol 9-O-β-D-glucopyranoside. The role of the second mentioned glucoside as a precursor of β-damascenone and 3-hydroxy-β-damascone was also established. With …
