[Study on GC fingerprint of the constituents in Herba Asari].

To establish a method for GC fingerprint determination of the chemical constituents in Herba Asari. GC and GC-MS were used to optimize the fingerprint determination method, and identify the main peaks in the GC fingerprint. A preferable method for GC fingerprint determination of the chemical constituents in Herba Asari was established. A general acquaintance of the chemical constituents in Herba Asari can be obtained by using the preferable GC fingerprint determination method, which is useful for quality evaluation of the crude drug of Herba Asari.
