Abstract

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.
