目的:研究壮药玉郎伞的化学成分。方法:用色谱法分离查尔酮类化合物,用波谱方法鉴定其结构。结果:从玉郎伞中分离和结构鉴定了2个查尔酮类化合物:cis-2,6-二甲氧基查尔酮(1);cis-17-甲氧基-7-羟基-苯骈呋喃查尔酮(2)。结论:2个化合物均为首次从该植物中分离得到,化合物1为首次报道核磁数据。
Objective: To study the chemical composition of Yulang umbrella. Methods: The chalcone compounds were separated by chromatography and their structures were identified by spectroscopic methods. Results: Two chalcone compounds were isolated and identified from the Yulang umbrella: cis-2,6-dimethoxy-chalcone (1); cis-17-methoxy-7-hydroxy- Furan chalcone (2). Conclusion: The two compounds were isolated from this plant for the first time. Compound 1 was the first report of NMR data.
