核桃楸树皮提取物的化学成分及其抗氧化活性研究
Chemical Constituents and Antioxidant Activities of the Extractives from Juglans mandshurica Maxim. Bark
摘要
Abstract
On the basis of chemical and spectroscopic evidence, 11 compounds, including 3 flavanols:pinobanksin(1), taxifolin(2) and ampelopsin(3), 3 flavonols:kaempferol(4), quercetin(5) and myricetin(6), and 5 flavonoid glycosides:afzelin(7), astragalin(8), quercitrin(9), isoquercitrin(10) and myricitrin(11), were isolated from the stem bark of Juglans mandshurica Maxim. This was the isolation of compounds 1, 3, 5, 6, 8 and 10 from this species for the first time. The antioxidant activities of the crude extract, partitioned fractions and isolated compounds were evaluated by DPPH free radical-scavenging assay. Results showed that EtOAc and H2 O partitioned fractions and compounds 1-6 exhibited strong antioxidant activities compared with controls.关键词
