A new p-hydroxyphenylacetyl flavonoid, diosmetin 7-(6''-O-p-hydroxyphenylacetyl)-O-beta-d-glucopyranoside (1), was isolated from the flowers of Chrysanthemum morifolium Ramat. 'huaiju' cv. nov. (Compositae), together with five known flavonoids, luteolin (2), diosmetin (3), diosmetin 7-O-beta-d-glucopyranoside (4), diosmin (5), and scolimoside (6), and four known caffeoylquinic acid derivatives, macranthoin F (7), 3,5-dicaffeoylquinic acid (8), 1,3-dicaffeoyl-epi-quinic acid (9), and chlorogenic acid (10). The structure of 1 was elucidated by UV, IR, ESI-TOF-MS, 1D, and 2D NMR spectroscopic methods. Cytotoxic activity of compounds 1-5 against human colon cancer cell Colon205 was investigated using MTT assays. Compounds 2 and 3 showed significant cytotoxicities against Colon205, with their IC(50) values being 96.9 and 82.9 microM, respectively. However, compounds 1, 4, and 5 showed little cytotoxic activity.
从菊花品种“怀菊”(菊科)的花中分离出一种新的对羟基苯乙酰黄酮,即香叶木素7 -(6''-O - 对羟基苯乙酰)-O-β -D -吡喃葡萄糖苷(1),同时还分离出五种已知的黄酮类化合物,木犀草素(2)、香叶木素(3)、香叶木素7 -O-β -D -吡喃葡萄糖苷(4)、地奥司明(5)和臭矢菜苷(6),以及四种已知的咖啡酰奎宁酸衍生物,大花金鸡菊素F(7)、3,5 -二咖啡酰奎宁酸(8)、1,3 -二咖啡酰-表奎宁酸(9)和绿原酸(10)。通过紫外光谱、红外光谱、电喷雾飞行时间质谱、一维和二维核磁共振光谱方法阐明了化合物1的结构。采用MTT法研究了化合物1 - 5对人结肠癌细胞Colon205的细胞毒性活性。化合物2和3对Colon205显示出显著的细胞毒性,其IC(50)值分别为96.9和82.9微摩尔。然而,化合物1、4和5显示出几乎没有细胞毒性活性。
