SOME MEDICINAL PROPERTIES OF CRAB APPLE (Eriolobus trilobatus) GENOTYPES IN ANTALYA PROVINCE

Abstract

A wild fruit, erect crab (Eriolobus trilobatus (Labill. ex Poiret) M. Roem.), is one of the arboreal trees of our country which is resistant against draught, has edible flavored fruits and is compatible for landscape. The aim of this study is to determine some medicinal properties of the erect crab species that spread in Antalya province. The amount of phenolic/ flavonoid substances and antioxidant activity values were determined in flowers, leaves and fruits samples. Leaf and flower samples were extracted as dried, while fruit samples were extracted as fresh. The analyses have been repeated in the second year. Total phenolic substance (TPS)in the leave samples was found to be 50- 140 (GAE mg g^-1), in flowers 19- 65 (GAE mg g^-1) and in fruits 0.3- 22 (GAE mg g^-1), the amount of flavonoid substance (TFS) was found in leave samples as 7- 37 (mg CE g^-1), in flower samples as 6- 24 (mg CE g^-1), in fruit samples as 0.4- 10 (mg CE g^-1). Antioxidant activity (AA) was found to be 35 % in flower samples, 33 % in fruit samples and 74 % in leaf samples. As a result of the analysis, crab apple flowers, leaves and fruit samples are very valuable in terms of medical, their should be considered as natural phenolic and antioxidant source.
