Popis: Jipi-japa (Carludovica palmata) and zamia (Zamia dressleri) are endemic species and are found mostly in the forests of Central America including Panama. In theory both the jipi-japa fruit and the stem and seeds of zamia are edible, although were only consumed occasionally mostly before modern times. The complete and detailed carotenoid analysis of the fruits of jipi-japa and the brown leaves of zamia was achieved using HPLC-DAD-MS technique, and co-chromatography with authentic samples. Plant extracts were subjected to HPLC separation on both C30 and C18 columns to make possible a better identification. Altogether 22 components were detected and 15 identified from the total extract of jipi-japa, and 32 components were detected and 17 identified from the extract of brown zamia leaves. From the identified carotenoids quite a number has special structures, which have recently been described in some of our previous papers on Central American plants (Murillo et al., 2011a, 2018; Gulyas-Fekete et al., 2013). It was found that almost 50 % of the total carotenoid content can be attributed to capsorubin in both plants. This carotenoid is present usually as a minor (2–3 %) carotenoid in other sources such as red pepper. Other carotenoids with κ end group are present in significant amounts, as well. Total carotenoid content was determined as the sum of yellow and red carotenoids (see Supplement). The main carotenoid, capsorubin, was isolated by open column chromatography on calcium carbonate and aluminium oxide and characterized by UV–vis, 1H and 13C NMR methods and compared to literature data. Capsorubin is a potent antioxidant even among carotenoids and have important biological effects. These two plants could be good sources for capsorubin either for isolation in gram amounts or for direct consumption.
