摘要

通过对玉米花柱和柱头的植物化学研究，分离出了 6 个新化合物，包括 3 个新的大果萜类倍半萜，分别命名为玉米烯 A (1)、玉米烯 B (2)、玉米烯 C (3)；以及 3 个新的ent-kaurane 类二萜，分别命名为玉米二萜 A (4)、玉米二萜 B (5)、玉米二萜 C (6)。通过物理性质、一维和二维核磁共振、HR-ESI-TOF-MS 等方法以及与文献数据的对比，阐明了它们的结构。此外，还讨论了这些化合物的化学分类学意义。

Three new macrocarpene-type sesquiterpenes and three new ent-kaurane-type diterpenoids isolated from the styles and stigmas of Zea mays L.

Phytochemical investigation of the styles and stigmas of Zea mays L. led to the isolation of six new compounds, including three new macrocarpene-type sesquiterpenes, named zeaen A (1), zeaen B (2), zeaen C (3), and three new ent-kaurane-type diterpenoids, named zeamaysditerpen A (4), zeamaysditerpen B (5), zeamaysditerpen C (6). Their structures were elucidated by physical properties, 1D and 2D NMR, HR-ESI-TOF-MS, and other methods, alongside comparison with literature data. Furthermore, the chemotaxonomic significance of these compounds was also discussed.
