目的 研究黄蜀葵Abelmoschus manihot花的化学成分。方法 采用色谱方法分离纯化，并经过波谱方法和理化性质鉴定化合物结构。结果 从黄蜀葵花的90%甲醇提取物中分离得到17个化合物，鉴定出黄酮及黄酮苷类化合物11个：槲皮素（1）、金丝桃苷（2）、杨梅素-3'-O-β-D-葡萄糖苷（3）、槲皮素-3'-葡萄糖苷（4）、8-（2"-pyrrolidinone-5-yl）-quercetin（5）、杨梅素（6）、floramanoside F（7）、isomyricitrin（8）、dihydromyricetin（9）、芦丁（10）、3-O-kaempferol-3-O-acetyl-6-O-（p-coumaroyl）-α-D-glucopyranoside（11）；核苷类化合物4个：腺嘌呤核苷（12）、5'-deoxy-5'-methylsulphinyl adenosine（13）、尿嘧啶（14）、烟酰胺（15）；及有机酸类2个（E）-9-octadecenoic acid（16）、没食子酸（17）。结论 化合物5、9、11～14为首次从锦葵科植物中分离得到，化合物15、16首次从黄蜀葵中分离得到。

Objective To study the chemical constituents from the flower of Abelmoschus manihot. Methods The compounds were isolated and purified by chromatographic techniques and their structures were identified on the basis of physicochemical properties and spectral data. Results Seventeen compounds were isolated in the 90% methanol extract from A. manihot and their structures were identified as quercetin (1), hyperoside (2), cannabiscitrin (3), quercetin-3'-glucoside (4), 8-(2"-pyrrolidinone-5-yl)-quercetin (5), myricetin (6), floramanoside F (7), isomyricitrin (8), dihydromyricetin (9), rutin (10), 3-O-kaempferol-3-O-acetyl-6-O-(p-coumaroyl)-α-D-glucopyranoside (11), adenosine (12), 5'-deoxy-5'-methylsulphinyl adenosine (13), uracil (14), nicotinamide (15), (E)-9-octadecenoic acid (16), and gallic acid (17). Conclusion Compounds 5, 9, and 11—14 are isolated from the Malvaceae family for the first time. Compounds 15 and 16 are isolated from this plant for the first time.
