摘要

杨桃属杨桃科,果实呈迷人的星形。对杨桃各部位的总酚和总黄酮含量及抗氧化能力进行了研究,以探索新的抗氧化化合物的活性提取物。树皮甲醇提取物中酚类成分含量最高(125 mg GAE/g)。而己烷、二氯甲烷和甲醇提取物的总黄酮含量最高,分别为45、92和72 mg QE/g。由于树皮具有最高的抗氧化能力,它比其他水果和树叶提取物含有更多的酚类化合物。树皮己烷、二氯甲烷和甲醇提取物的总抗氧化能力分别为62、117和151 mg AAE/g。结果表明,树皮部分具有较高的抗氧化能力,可以作为酚类化合物的良好来源。水果和叶子部分也是抗氧化化合物的丰富来源。达卡大学药学院。科学21(2):147-151,2022(12月)

Evaluation of Total Phenolic, Flavonoid Content and Antioxidant Capacity of Different Parts of Averrhoa carambola L.
Averrhoa carambola L. belonging to the Oxalidaceae family has fruits with attractive star shape. Total phenolic and flavonoid content and antioxidant capacity of various parts of A. carambola have been studied to explore active extracts for novel antioxidant compounds. Methanol extract of bark contained the highest amount of phenolic constituent (125 mg GAE/g of dry extract). However, hexane, dichloromethane and methanol extracts contained the maximum number of flavonoids and were 45, 92 and 72 mg QE/g of dry extract, respectively. Since the bark possessed the highest antioxidant capacity, it contained more phenolic compounds than other extracts of fruits and leaves. Total antioxidant capacity of hexane, dichloromethane and methanol extracts of bark were 62, 117 and 151 mg AAE/g of dry extract, respectively. The results recommend that the bark part can be a good source of phenolic compounds as it showed the highest antioxidant capacity. The fruit and leave parts are also rich sources of antioxidant compounds. Dhaka Univ. J. Pharm. Sci. 21(2): 147-151, 2022 (December)
