摘要
The chemical composition of the essential oil of the aerial part of Nepeta pannonica L. from Kazakhstan was investigated by GC and GUMS. Sixty components were characterized from N. pannonica with 1,8-cineole (28.9%), and 4 alpha,7 beta,7a alpha-nepetalactone (14.3%) as the major constituents. The oil of N. pannonica was more phytotoxic to bentgrass compared to lettuce seeds, with 100% growth inhibition observed at 0.3, and 1.0 mg/mL, respectively.
