Artvin’de doğal yetişen Arbutus andrachne L.’nin meyve ve çiçeklerinin toplam fenolik madde içeriği ve antioksidan aktivitesinin belirlenmesi

Abstract

Arbutus andrachne L. is widespread as Mediterranean enclave in the Black Sea Region, while it is found naturally in the Mediterranean and Aegean Region of Turkey. In this study, antioxidant activity, total phenolic and total flavonoid contents were determined in the fruits and flowers of A. andrachne samples obtained from Artvin. The antioxidant activity was analyzed using the DPPH radical scavenging activity and FRAP methods. In addition, while the total phenolic content was determined using the Folin-Ciocalteu assay, the aluminum chloride assay was used to measure the total flavonoid content. According to the results, the flowers of A. andrachne have higher contents in respect to antioxidant activity (104.81±4.75 μmol FeSO4.7H2O/g dry sample), phenolic (43.57±2.85 mg GA/g dry sample) and flavonoid (114.28±1.49 mg Que/g dry sample) than its fruits. It was concluded that the flowers and fruits of A. andrachne are good source of phenolic and antioxidant.

Hozat Kayısı Çekirdeğindeki Toplam Flavonoid Düzeyinin Tespiti

“…Farklılığın aynı iklim bölgesinde (Damghan) yetiştirilen fıstık çekirdek çeşitlerinin çalışmada kullanılmasından kaynaklandığı düşünülmektedir. Bunlara ek olarak bitkisel kaynaklarda farklı bitki kısımlarının toplam flavonoid miktarları değişkenlik gösterebilmektedir (4,5,6]…”

Seed Germination Behavior, Molecular Analysis of Four Populations of Arbutus andrachne Species from Greece, and Cultivation Practice for Producing High-Quality Plants

“…andrachne is a valuable phytogenetic resource due to its medical and floricultural value. Its fruits are a good source of minerals, ascorbic acid, phenols, and antioxidants and are characterized by the low content in soluble sugars [5][6][7]. Furthermore, the A. andrachne species with the peeling, red-brown bark, the attractive white-cream spring flowers, and the red edible autumn fruits, is drought tolerant, and thus can be a suitable landscaping choice in the arid and semi-arid environments of the Mediterranean basin, even in the urban residential landscapes.…”
