Endogenous indoleamine profiles in various ex vitro and in vitro tissues of commercially important Coffea canephora were analyzed by using a high performance liquid chromatography and further confirmed with electrospray ionization mass spectrometry. High content of serotonin (SER) (98.54 ± 5 µg/g) and melatonin (MEL) (115.25 ± 6 µg/g) were found in freshly harvested seeds of C. canephora followed by zygotic embryo (65.25 ± 4 and 96.54 ± 5 µg/g freshweight) and endosperm(34.08 ± 2 and 51.08 ± 4 µg/g fresh weight) of ripened fruits. Similarly endogenous pools of SER and MEL were moderate in in vitro tissues of C. canephora, i.e. callus (25.85 ± 2 and 75.74 ± 4), somatic embryos (31.88 ± 2 and 19.30 ±2 µg/g fresh weight) and in vitro regenerated plant stalk (15.78 ± 1 and 38.25 ± 3 µg/g fresh weight), respectively. In view of significant levels of both SER and MEL in various tissues and beans of Coffea, further investigations on their physiological role needs to be investigated.
