ABSTRACT

Using GC-MS-DC techniques, we identified 24 constituents in the essential oil of Matricaria chamomilla L. collected from Shanghai. And using GC we found out that the contents of its constituents were notably different between fresh and dry inflorescences, and its quantities in the examples were changed from time to time during the day.
