Chemical Compositions and DPPH Radical Scavenger Activity in Different Sections of Safflower

Chemical compositions and DPPH radical scavenger activity in different sections of safflower (Carthamus tinctorious L.) were investigated. Protein contained 28.39% in sprout and fat contained 20.47% in seed, respectively. Linoleic acid as predominant unsaturated fatty acid of safflower contained 80.01% in sprout and 78.27% in seed. Glucose contained 1253.6mg% in sprout and fructose contained 970.7mg% in sprout. Sucrose contained 912.0mg% in flower bud. Succinic acid was included 2795.3 mg% in flower, malic acid was included 2054.8mg% in leaf. K as minerals contained 2826.8mg% in leaf and 2613,6 mg% in sprout, Ca contained 1999.8mg% in leaf and 1160.9mg% in sprout. Total phenolics contained 5.8%, 4.7%, 4.4% in flower, sprout and leaf, and total flavonoid contained 6.5%, 2.5%, 2.0% in flower, sprout and leaf, respectively Serotonin-I (Ν- [2- (5-hydroxy - l Η- indol -3- yl)ethyl] ferulamide) as serotonin compounds was determined 147.7mg% in seed, serotonin - II (Ν-［2-(5-hydroxy-lΗ-indo-1-3yl )ethyl]-p-coumaramide) was determined 155.4 mg% in seed. Acacetin as flavonoid compounds was contained 116.5mg% in seed. Luteolin as flavonoid compounds was identified 388.3mg% in sprout, luteolin 7-glucoside was determined 692.3mg% in leaf, respectively. DPPH radical scavenger activity was measured by DPPH method, it was shown higher 114.2% in ethanol extract of flower and 113.6% in ethanol extract of leaf than 88.05% of 100 ppm BHA as chemical antioxidant.
