ABSTRACT

Hovenia dulcis Thunberg is widely distributed in East Asia, where it is well known as a food, but it is rarely consumed in Western countries. Information about its composition is scarce and focused on southern hemisphere genotypes. In the present research, the main bioactive compounds of H. dulcis pseudofruits were characterised using phytochemical analysis (HPLC fingerprint) to improve knowledge about this plant and support development of potential food applications. These preliminary results showed high levels of catechins (157.18 ± 34.34 mg/100 gFW) and other phenolic compounds responsible for antioxidant properties. Concentrations of ferulic acid were particularly high (9.66 ± 1.76 mg/100 gFW) and further studies would advance exploitation of this plant-food.

ABSTRACT

Interest in new sources of anti-inflammatory and antioxidant compounds has recently become a major research issue, with the cornelian cherry (Cornus mas L.) receiving particular attention for its significant amounts of phenolic compounds and vitamins, which exhibit a wide range of biological and pharmacological properties. This study was aimed at increasing knowledge regarding the cornelian cherry in Italy through the analysis of biologically active substances in the locally available genotype "Chieri". Spectrophotometric methods were applied to evaluate antioxidant activity, total anthocyanin content and total polyphenolic content. Identification and quantification of the main phytochemical compounds (polyphenols, monoterpenes, organic acids and vitamin C) was performed via high performance liquid chromatography coupled to a diode array detector. C. mas extracts showed high levels of total soluble solids and low acidity. High amounts of phenolic secondary metabolites were observed, with particular reference to anthocyanins (134.71 mgC3G/100 gFW), which confer remarkable nutraceutical properties to the analysed samples. These results highlight the potential of C. mas fruits as a good source of natural antioxidants, suggesting their use as a functional food. Future studies should focus on identifying other specific phytochemical compounds and the genetic traits of local varieties in order to improve cornelian cherry cultivars for food and medicine production.
