Characterization of an Italian landrace of Cyclanthera pedata (L.) Schrad. of herbal and horticultural interest

Abstract Caigua ( Cyclanthera pedata (L.) Schrad.) is a native species of the Andes. Its fruits are recently gaining attention as herbal and healthy product. A landrace traditionally cultivated in Camonica Valley (Italian Alps), called “Ciuenlai” (or “Milione/Milioncino”), almost unknown. For this reason, phytochemical, nutritional ecological (functional strategy) characterization was carried out. Phytochemical analyses were performed considering its fruits, leaves, sprouts, seeds, compared with commercial South American plant material. Fruits showed similar content phenolic compounds but lower saponins flavanones dihydroflavonols than comparison samples. Conversely, caffeoylquinic acid (frequently considered quality marker for use) four times higher (0.64 ± 0.04%) comparing variety grown same area (0.15 0.01%). Interestingly, leaves sprouts resulted rich secondary metabolites, including dihydroflavonols, suggesting that these parts could be eligible use. Considering agronomical features, more ruderal strategy, different growth, producing earlier season, much smaller variety. have developed an adaptation to peculiar climatic conditions mountain areas Valley, from area. The use useful strategy valorisation, other promotion product typical food.
