Anthocyanin pigment content of barberry fruit and six grape varieties " Betch , Torkman ,Rokh Siah , Siah Ghochan , Sine Kaftaree and Shahani were investigated using optical spectroscopy (The pH- differential method), including quantitation of monomeric anthocyanin pigment( red color indice), and polymeric color , color density and percent polymeric color as indices for degradation .The result showed that, there was significantly difference between samples in monomeric anthocyanins, polymeric color , color density and percent polymeric color. Monomeric anthocyanins were 2990 , 2333 , 2170 , 1632 , 1177 , 1050 , 202 mg/L for shahni,Rokh Siah , Siah Ghochan,Torkman , Sine Kaftaree , Barberry fruit and Betch respectively. Polymeric color were 41, 36, 27,20, 13,11 for Rokh Siah,Torkman, Betch, Sine Kaftaree,Barberry fruit and shahani binary and Siah Ghochan respectively . Color density were 129 , 97, 79, 47, 44, 42 for shahani , Siah Ghochan and Sine Kaftaree binary , Rokh Siah , Barberry fruit , Torkman ,and Betch respectively. percent polymeric color were %80 , %62 , %41 , % 28, % 21, %11, %10 for Torkman , Betch , Rokh Siah , Barberry fruit , Sine Kaftaree , Siah Ghochan and shahani respectively. It was concluded that shahani , Siah Ghochan and Sine Kaftaree have a proper potential for producing Anthocyanin pigment.
