摘要
目的研究麻花头属植物麻花头Serratulachinensis干燥块根的化学成分。方法采用硅胶、SephadexLH.20、ODS柱色谱和制备HPLC等方法进行分离,并通过理化常数和NMR等各种波谱学办法鉴定化合物结构。结果从广升麻干燥块根95%乙醇提取物的正J-醇部位分离得到了16个化合物,分别鉴定为20.羟基蜕皮甾酮(1)、polypodineB(2)、carthamosterone(3)、20,22.异内叉基.20-羟基蜕皮甾酮(4)、24-epi.abutasterone(5)、polypodineC(6)、coronatasterone(7)、20-羟基蜕皮甾酮2-O—β—D-葡萄糖苷(8)、20-羟基蜕皮甾酮25-O—β—D-葡萄糖苷(9)、polypodineB20,22.acetonide(10)、shidasterone(11)、2-O-乙酰基.20.羟基蜕皮甾酮(12)、3-O-乙酰基.20-羟基蜕皮甾酮(13)、20。羟基蜕皮甾酮-20,22-缩丁醛(14)、24-methylene—shidasterone(15)及ajugasteroneD(16)。结论化合物2、4、5、7~10、12、15、16为首次从该植物中分离得到,化合物5、7~10、16为首次从麻花头属植物中分离得到。
Objective To study the chemical constituents from the roots tubers of Serratula chinensis. Methods The chemical constituents were separated and purified by silica gel, Sephadex LH-20, ODS column chromatographies, and preparative HPLC. Their structures were determined by physicochemical properties and spectral data. Results Sixteen compounds (ecdysteroids) were isolated from the n-butanol fraction of 95% ethanol extract in the root tubers of S. chinensis, and their structures were identified as 20-hydroxyecdysone (1), polypodine B (2), carthamosterone (3), 20-hydroxyecdysone-20, 22-monoacetonide (4), 24-epi-abutasterone (5), polypodine C (6), coronatasterone (7), 20-hydroxyecdysone 2-O-β-D-glucopyranoside (8), 20-hydroxyecdysone 25-O-β-D- glucopyranoside (9), polypodine B 20, 22-acetonide (10), shidasterone (11), 2-O-acetyl-20-hydroxyecdysone (12), 3-O-acetyl-20- hydroxyecdysone (13), 20-hyderoxyecdysone-20, 22-butylidene acetal (14), 24-methylene-shidasterone (15), and ajugasterone D (16). Conclusion Compounds 2, 4, 5, 7--10, 12, 15, and 16 are isolated from this plant for the first time, and compounds 5, 7--10, and 16 are found in the plants of genus Serratula L. for the first time.
