BURUK, BURUK OLMAYAN ve YABANİ (ANAÇ) HURMALARIN TOPLAM FENOLİK BİLEŞEN, ANTİOKSİDANT KAPASİTE ve IN-VITRO SİMULE EDİLMİŞ BİYOALINABİLİRLİK ÖZELLİKLERİ

Abstract

Persimmon which is widely known as "Trabzon Hurması" and "Cennet Meyvesi" is a very popular fruit with bright orange color. In the presented study, extractable, non-extractable, total phenolic content (TPC), antioxidant capacity (AC) and bioaccessibility of Trabzon persimmons (astringent, non-astringent and wild persimmon) were determined. The results of this study indicated that all types of persimmons have great importance both on TPC, AC and bioaccessibility. Compared to astringent and non-astringent types, the wild persimmon type had the highest TPC. Another attractive result from this study, although the wild persimmons do not prefer for consumption, the results demonstrated that the bioaccessible phenolics of this type of persimmons were found to be 6.7 fold higher than the non-astringent types and 4.7 fold higher than the astringent types. Especially the wild type of persimmon is a good source of natural antioxidant and further studies should be carried out for wild type persimmon.

Antioxidant and 3-hydroxy-3-methylglutaryl Coenzyme A reductase inhibitory activities of some plant samples

“…In different varieties of pomegranate, phenolic compounds (ellagic acid, gallic acid, chlorogenic acid, caffeic acid, vanillic acid, ferulic acids trans-2-hydrocinnamic acid, quercetin) and flavonoids (catechin, rutin, quercetin and phloridzin) were identified (Hmid et al, 2017;Djenidi et al, 2020;Tekin and Kucukbay et al, 2020). Phytochemical analysis by Lee et al (2012), Murathan (2020) and Aydin (2021) reported the presence of tartaric acid, malic acid, lactic acid, gallic acid, citric acid, catechins, phenols, flavonoids and ascorbic acid in persimmon fruit. Radish fruits are rich in flavonoids (such as myricetin, catechin, epicatechin, and quercetin), phenols (e.g.…”

“…Comparative antioxidant analysis between astringent, nonastringent and wild types of persimmons by Aydin (2021) indicated that the wild type had higher antioxidant potential than the other types. The ABTS, CUPRAC, DPPH, and FRAP activities were 112.…”
