Abstract

Üzüm çekirdekleri, kabukları ve şarabın insan sağlığına olan etkileri ile ilgili çok yoğun araştırma gerçekleştirilmesine rağmen salkım iskeletleri ile ilgili yok denecek kadar az çalışma bulunmaktadır. Bu araştırmanın temel amacı 49 adet Vitis vinifera L. çeşidine ait salkım iskeletlerinin toplam fenolik bileşik (TFB), trans-resveratrol, kateşin ve epikateşin düzeylerinin belirlenmesidir. TFB düzeyi 17025-123250 mg GAE kg-1 kuru ağırlık, trans-resveratrol düzeyi 23.44-70.38, kateşin düzeyi 843-14144 ve epikateşin düzeyi 0-981 mg kg-1 kuru ağırlık aralıklarında belirlenmiştir. Sonuçlar doğrultusunda gelecek araştırmalarla üzüm salkım iskeletlerinin insan sağlığı açısından önemli biyoaktiviteye sahip oldukları ve biyofonksiyonel gıda ya da gıda takviyesi olarak kullanılabileceği sonucuna varılmıştır.

Total phenolic compound and trans-resveratrol levels of some grape (Vitis vinifera L.) stems

Abstract

Grape seeds, skins and wine have been studied widely due to their beneficial effects on human health. However, there are only few studies from grape stems extracts. Therefore, the main objective of the present study was the assessment in stem extracts from 49 Vitis vinifera L. varieties of the total polyphenolic content (TPC), trans-resveratrol, catechin and epicatechin. The range of the TPC in grape stem extracts was from 17025 to 123250 mg GAE kg-1 dry weight. Trans-resveratrol levels were range from 23.44 to 70.38, catechin levels were range from 843 to 14144 and epicatechin levels were range from 0 to 981 mg kg-1 dry weight. the present results indicate that grape stem extracts possess have important phenolic compounds, and thus they could be exploited, biofunctional foods or food supplements.
