Variations of nootkatone and valencene levels during the development of grapefruit

The distribution of nootkatone and valencene in grapefruit was determined by gas-liquid chromatography-mass spectrometry (GLC-MS). Changes in the concentration of valencene and nootkatone were observed during the development of fruits, increases in these compounds coinciding with the linear and the...

Description
Summary:The distribution of nootkatone and valencene in grapefruit was determined by gas-liquid chromatography-mass spectrometry (GLC-MS). Changes in the concentration of valencene and nootkatone were observed during the development of fruits, increases in these compounds coinciding with the linear and the maturation steps, respectively. The possible participation of valencene and 2-hydroxyvalencene as precursors in the biosynthetic pathway for nootkatone in grapefruit is discussed
