Abstract: Micro-constituents in citrus fruits, such as terpenes and flavonoids, are important for their contribution to aroma and taste. In this work, gas- and liquid-chromatography coupled with mass spectrometry (MS) techniques were used to investigate micro-constituents in Asian citrus. Firstly, volatile profiling was conducted for less well-studied Asian citrus: pomelo, kumquat, and calamansi. Following this, profiling was expanded to comprehensively investigate both volatile and non-volatile compounds in two Japanese citrus varieties, kabosu and yuzu. Additionally, by applying this profiling approach, changes in the secondary metabolite profile due to maturation or genetic differences were explored in Qicheng orange and Asian citrus hybrids, respectively. Lastly, to expand current knowledge on non-volatile compounds in citrus, neutral loss and tandem MS were used to screen for flavonoid and limonoid glycosides in Qicheng orange. These investigations provide substantial knowledge of the variety and abundance of micro-constituents in Asian citrus which is essential for flavour recreation.
