LA QUALITÀ DEL MANGO PRODOTTO IN SICILIA, ASPETTI COLTURALI DELLA PAPAYA, DEL LICI E DEL NESPOLO DEL GIAPPONE
2016
L’introduzione di specie arboree da frutto di origine tropicale e subtropicale in Sicilia non è nuova ma solo negli ultimi anni si assiste ad una crescita esponenziale delle superfici investite. Infatti, se alberi come il Nespolo del Giappone fanno ormai parte della nostra cultura frutticola da decenni, mango, lici e papaia fino a qualche anno fa erano poco conosciuti sulle nostre tavole. Nel giro di poco tempo questi frutti hanno conquistato un posto stabile tra le preferenze del consumatore con spazi di mercato in continuo aumento. La coltivazione di questi fruttiferi di origine tropicale presuppone precise risposte sulla fattibilità di nuovi impianti e sulle modalità di conduzione agrono…
Autophagic cell death induced by Litchi fruit extracts in human colon cancer cells.
2016
Litchi chinensis is a tropical fruit which cultivation has been recently introduced in Sicily. Some findings have shown that Litchi extracts display antitumor effects but the underlying mechanisms have not been elucidated. This study focuses on the effects of Litchi hydro-alcoholic extracts in colorectal cancer cells. The results indicated that Litchi exocarp (peel), mesocarp (pulp) and endocarp (seeds) extracts reduce the viability of HT-29 colon cancer cells in a dose dependent manner. This effect was accompanied with G2/M arrest of the cell cycle followed by cell death. Interestingly, exocarp and endocarp extracts triggered an autophagic response in the first phase of treatment (16-24h) …
Increasing Yield and Antioxidative Performance of Litchi Pericarp Procyanidins in Baked Food by Ultrasound-Assisted Extraction Coupled with Enzymatic…
2018
Extraction with organic solvents is a traditional method to isolate bioactive compounds, which is energy-wasting and time-consuming. Therefore, enzyme and ultrasound treatments were combined to assist the extraction of oligomeric procyanidins from litchi pericarp (LPOPC), as an innovative approach to replace conventional extraction methods. Under optimum conditions (enzyme concentration 0.12 mg/mL, ultrasonic power 300 W, ultrasonic time 80 min, and liquid/solid ratio 10 mL/g), the yield of LPOPC could be improved up to 13.5%. HPLC analysis indicated that the oligomeric procyanidins (OPC) content of LPOPC from proposed extraction was up to 89.6%, mainly including (&minus
