Abstract

Extraction of bio compounds from plant materials is one of the most important step of the processes such as dietary supplement production and recovery of the compounds from the industrial wastes. It is highly affected from the factors such as solvent type, particle size, extraction time and temperature. To determine the total phenolics, individual phenolic profile and antioxidant activity of Hawthorn (Crataegus orientalis) fruit extracted with different solvents and to specify the best solvent for extraction of phenolics were aimed in this research. Fruits, picked from wild growing trees in Beyşehir, were extracted with water, methanol and methanol:water (1:1) mixture. Highest total phenolics and antioxidant activity were observed in methanol:water extract. While gallic acid was extracted effectively in water, methanol:water mixture was the best solvent for extraction of procyanidin B1, procyanidin B2, (-)- epicatechin, epigallocatechin gallate and rutin.
