This study was aimed to determine qualitative and quantitative changes of the composition of phenolic compounds
in leaf of five apricots (Prunus armeniaca L.) cv. by season.
These apricot varieties are “Hacihaliloglu” (HH), “Hasanbey” (HB) “Kabaasi” (KB) “Ismailaga” (IA) and
“Cekirge” (CG) which are cultivar in Malatya province of Turkey. Sampling process was carried out in three
different seasons being as April (Spring), June (Summer) and November (Autumn) corresponding by season. HPLC
method was used for the determination of phenolic compounds in the samples. The results showed that, the most
common phenolic compounds species in apricot leaves were chlorogenic acid, rutin, -(-) catechin and naringin. At
the end of third period, while rutin and catechin contents were increased, chlorogenic acid and naringin were
As a result, Chlorogenic acid level of HH leaves were 1.7, 1.6, 1.5 and 1.3 times higher than that of KB, CG, IA
and HB leaves in April, respectively. The chlorogenic acid in HH, CG and KB leaves according by seasons decreased
by 43.81, 48.15, 52.50% from April to November, respectively. Rutin levels of in all leaves showed the highest
increase with 83.56% in IA varieties. It was determined that there was an increase of HH 77.33%, HB 66.66% and
KB 63.22% in apricot leaves.
