The flavones 5,6-dihydroxy-7,3′,4′-trimethoxyflavone (1), 5,6,4′-trihydroxy-7,3′-dimethoxyflavone (2), 5-hydroxy-3′,4′,6,7-tetramethoxyflavone, 5,7,3′-trihydroxy-6,4′,5′-trimethoxyflavone, ladanein, and hispidulin were isolated from the methanolic extracts of the aerial parts of Artemisia argyi and structures of the compounds were elucidated on the basis of their spectral data. These flavones inhibited farnesyl protein transferase with IC50 values of 25 - 200 μg/mL. Compound 2 inhibited proliferation of a couple of tumor cell lines and also inhibited neovascularization in a chick chorioallantoic membrane assay. Without loss of body weight of nude mice, compounds 1 and 2 inhibited growth of a colon tumor (SW620) by 44.6 % and 14.6 %, respectively.
从艾蒿地上部分的甲醇提取物中分离出黄酮类化合物5,6-二羟基-7,3′,4′-三甲氧基黄酮(1)、5,6,4′-三羟基-7,3′-二甲氧基黄酮(2)、5-羟基-3′,4′,6,7-四甲氧基黄酮、5,7,3′-三羟基-6,4′,5′-三甲氧基黄酮、ladanein和hispidulin,并根据其光谱数据阐明了这些化合物的结构。这些黄酮类化合物抑制法呢基转移酶,IC50值为25-200微克/毫升。化合物2抑制了几个肿瘤细胞系的增殖,并在鸡绒毛尿囊膜实验中抑制了新生血管的形成。在不影响裸鼠体重的情况下,化合物1和2分别抑制结肠肿瘤(SW620)的生长44.6%和14.6%。
