目的 研究菊科植物红花Carthamus tinctorius的化学成分。方法 通过大孔吸附树脂、硅胶柱色谱、Sephadex LH-20色谱以及制备HPLC等方法进行分离纯化，并鉴定化合物的结构。结果 从红花水提部分得到2个倍半萜类化合物，通过波谱学方法分别鉴定为 (?)-methyl dihydrophaseate（1）和 (?)-(9E)-methyl dihydrophaseate（2）。结论 其中化合物2为新化合物，命名为红花酯A。

Objective To investigate the chemical constituents from the flowers of Carthamus tinctorius. Methods Two sesquiterpenes were isolated and purified by macroporous resin, silica gel, Sephadex LH-20, and preparative HPLC. Results Two sesquiterpenes were isolated from the water extract in the flowers of C. tinctorius and identified as (?)-methyl dihydrophaseate (1) and (?)-(9E)-methyl dihydrophaseate (2). Conclusion Compound 2 is a new compound named carthamate A.
