华丽芒毛苣苔化学成分研究

 目的 研究华丽芒毛苣苔（Aeschynanthus superbus Clarke）的化学成分。方法 采用各种色谱法分离，运用多种波谱技术鉴定结构。结果 从华丽芒毛苣苔甲醇提取物中分离得到9个化合物：β-谷甾醇(1)，羽扇豆醇(2)，carissol(3)， 3-hydroxy-20(29)-lupen-28-oic acid(4)，3β-hydroxy-5，12-oleanadien-28-oic-acid(5)， 芹菜素(6)， 5，7，4′-三羟基-6-甲氧基黄酮(7)，熊果酸(8)和β-胡萝卜苷(9)。结论 化合物1~9为首次从该植物中分离得到，其中2～7为首次从该科植物中得到， 8～9为首次从该属中分离得到。

Chemical Constituents of Aeschynanthus superbus Clarke

OBJECTIVE To study the chemical constituents of Aeschynanthus superbus Clarke. METHODS Column chromatographic techniques were applied to isolate the constituents. EI-MS and NMR were used to identify the structures of the separated compounds. RESULTS Nine compounds were isolated from the methyl hydroxide extract of A. superbus， whose structures were elucidated as β-sitosterol(1)， lupeol(2)， carissol(3)， 3β-hydroxy-20(29)-lupen-28-oic acid(4)， 3-hydroxy-5，12-oleanadien-28-oic-acid(5)， apigenin(6) ， 5，7，4'-trihydroxy-6-methoxyflavone(7)， ursolic acid(8) and β-daucosterol(9). CONCLUSION Compounds 1-9 are isolated for the first time from this plant. Compounds 2-7 are isolated for the first time from Gesneriaceae， and compounds 8-9 are isolated for the first time from the Aeschynanthus.
