Identification and Quality Assessment of Chrysanthemum Buds by CE Fingerprinting

Abstract EN

A simple and efficient fingerprinting method for chrysanthemum buds was developed with the aim of establishing a quality control protocol based on biochemical makeup.

Chrysanthemum bud samples were successively extracted by water and alcohol.

The fingerprints of the chrysanthemum buds samples were obtained using capillary electrophoresis and electrochemical detection (CE-ED) employing copper and carbon working electrodes to capture all of the chemical information.

10 batches of chrysanthemum buds were collected from different regions and various factories to establish the baseline fingerprint.

The experimental data of 10 batches electropherogram buds by CE were analyzed by correlation coefficient and the included angle cosine methods.

A standard chrysanthemum bud fingerprint including 24 common peaks was established, 12 from each electrode, which was successfully applied to identify and distinguish between chrysanthemum buds from 2 other chrysanthemum species.

These results demonstrate that fingerprint analysis can be used as an important criterion for chrysanthemum buds quality control.
