چکیده مقاله:
Pistachio (Iranian type) is one of the principal agriculture plants in Iran. Regarding to thepresence of the phenolics in Pistachio hulls very few studies have been reported in general,particularly considering Iran’s pistachio hulls. In the present study, polyphenols in the hulls ofthe two most important Iran’s pistachio varieties (Kerman and Damghan) were extracted usingmethanol and ethanol solvent and various dilutions of these solvents with water. Folinmethod as one the most reliable procedure for the phenolics measurement was used in thisstudy, to determine the concentration [1-3]. Among the solvents used for Damghan variety theyield of the ethanolic extract at the level of the 50:50 (H2O) was higher (28.8 mg Polyphenolsper g the denied pistachio hulls). While the yield of the ethanolic extract at the ratio of 75:25(H2O) from Kerman’s pistachio hulls was higher among the yield obtained from other solventsused for this variety (19.8 mg Polyphenols per g the denied pistachio hulls). The relationshipbetween plant phenolics and antioxidant activities is well documented in the literature.In order to determine the antioxidant activities of the ethanolic extracts from the Pistachiohulls according to the defined procedures, detailed experiments are being under taken inour laboratory.
