Comparative study of phenolic profile of fruit and juice samples of a progeny of ‘Meana’ × ‘Florina’ from an Asturian cider apple breeding program

Abstract

they exhibited a higher phenolic content than 'Meana' apple juice. Although flavan-3-ol, procyanidin and dihydrochalcone levels were similar to those observed in 'Meana' apple, flavonol levels increased slightly. Furthermore, it is worth noting that hydroxycinnamic acid concentration was up to three times higher. This fact could lead to an increase in cider astringency and color, as well as in cider aroma. Thus, this methodology is proposed to be applicable to the determination of the phenolic profile in other fruit and/or plant extracts.

Relationship between hydroxycinnamic acids and the resistance of apple cultivars to rosy apple aphid

“…Apple juice samples were analysed by UHPLC-DAD-ESI-QToF/MS using a previous validated method [28] using an ACQUITY UPLC™ system from Waters (Milford, MA, USA), equipped with a binary solvent delivery pump, an autosampler, a column compartment and a DAD detector. A reversephase column (Kinetex™ C18 1.7 μm, 2.1 mm × 100 mm) and a filter (Krudkatcher ™ ULTRA HPLC in-line filter, 0.5 μm depth filter × 0.004 in ID) from Phenomenex (Torrance, CA, USA) were used at 40 °C.…”

Some Phytochemical Characteristics of Cherry Cultivars and Relations Between These Characteristics

“…For this reason, studies are primarily conducted on the phytochemical compositions of existing genetic resources (Polat et al, 2018;Gundogdu et al, 2018;Çavuşoğlu et al, 2018;Karaat et al, 2019;Acero et al, 2019;Okatan, 2020). New genotypes are developed by using parents with superior qualities in terms of desired properties in classical and modern breeding methods (Cevallos-Casals et al, 2006;Ramirez-Ambrosi et al, 2015;Yazici and Şahin, 2016;Sahoo et al, 2017).…”

Synthesis of Isorhamnetin-3-O-Rhamnoside by a Three-Enzyme (Rhamnosyltransferase, Glycine Max Sucrose Synthase, UDP-Rhamnose Synthase) Cascade Using a UDP-Rhamnose Regeneration System

“…Quercetin-7- O -rhamnoside has a strong inhibitory effect on the replication of the porcine diarrhea virus [8] and its structural analogue, quercetin-3- O -rhamnoside also shows a good inhibitory effect on the human influenza A/WS/33 virus [8,9]. As one kind of isorhamnetin glycosides, the isorhamnetin-3- O -rhamnoside only has been found in the Cruciferae [10], Caesalpinia gilliesii [11], Formosan A. Purpurea [12], and Asturian cider apple [13]. The isorhamnetin-3- O -rhamnoside was reported to exhibit moderate antioxidant activity [14] and the other biological properties remain to be studied.…”

“…The methods of extraction for the isorhamnetin-3- O -rhamnoside have been reported [10,11,12,13,14]. These methods are mainly based on the chemical reagents and plants resources and could be unfriendly to the environment.…”
