본 연구에서는 자두류 중 피자두를 생육시기별로 채취하여 총 8종에 대한 일반성분 및 총 페놀성 화합물, 축합형 탄닌 함량을 조사하였으며, DPPH 자유 라디칼 소거능과 linoleic acid에 대한 항산화 효과를 살펴보았다. 피자두 과육의 수분함량 및 아세톤추출물의 조회분, 조단백, 조지방 함량을 분석한 결과, 시료 1, 5, 8번은 각각 수분 88.52, 87.01, 83.56, 조분 7.12, 3.35, 3.57, 그리고 조단백7.52, 5
This study was performed to evaluate the antioxidant effect of Prunus salicina Lindl. cv. Soldam at different growth stages (sample 1-8). Previous studies shows that this fruits possess hematopoiesis effect, osteoporosis prevention, and antimutagenic effects. Prunus salicina Lindl. cv. soldam was picked in every 5 days from the 40th day before harvesting date for marketing in Gimcheon, Gyeongbuk. The fruits at different growth stages (sample 1-8) were extracted with 60 acetone and chlorophyll in the extracts was removed. In proximate compositions, the contents of moisture of sample 1, 5, 8 were 88.52, 87.01, 83.56 ; crude ash were 7.12, 3.35, 3.57 ; crude protein were 7.52, 5.55, 3.85 ; crude fat contents were 3.20, 0.99, 5.15, respectively. The contents of total polyphenols and condensed tannin in the acetone extracts from sample 1, 5, 8 were 10.67, 4.05, 2.57, and 8.36, 3.11, 1.88, respectively. The antioxidantive effect of acetone extracts from immature fruits showed strong scavenging effect on DPPH free radicals. The RC values of the extracts from sample 1, 2 were 2.23, 9.70 g/mL, respectively while those of butylated hydroxyanisole (BRA) was 5.25 g/mL. The extracts from immature fruits showed over 85 inhibition on peroxidation of linoleic acid at 100 g/mL as determined by both the ferric thiocyanate (FTC) and the thiobarbituric acid (TBA) method.
