A new flavone glycoside, eupatilin 7-O-β-d-glucopyranoside (1) and a new flavone, 5,6,2′,4′-tetrahydroxy-7,5′-dimethoxyflavone (2), were isolated from Artemisia argyi. Their structures were unambiguously elucidated by extensive spectroscopic analysis. Both flavonoids were evaluated for in vitro anticoagulation activities. Compound 1 significantly extended thrombin time. Compound 2 had obvious effect
从银蒿中分离到一种新的黄酮苷,紫杉醇7- O - β - d-吡喃葡萄糖苷(1)和一种新的黄酮,5,6,2',4'-四羟基-7,5'-二甲氧基黄酮(2)。。通过广泛的光谱分析清楚地阐明了它们的结构。评价了两种类黄酮的体外抗凝活性。化合物1显着延长了凝血酶时间。化合物2在增加凝血酶原时间上具有明显的作用。
