Abstract:
Objective To set up the quality control standard for Leaf of Chinese Holly; To provide basis for the utilization and development of Leaf of Chinese Holly.Methods Ten batches of Leaf of Chinese Holly samples from different habitats were collected, and the properties were described. The crosscutting and powder of leaf was under microscopic identification. Chlorogenic acid was set as reference substance to conduct thin-layer identification. Moisture, total ash, and acid-insoluble ash of the 10 batches were detected. HPLC was used to detect chlorogenic acid in Leaf of Chinese Holly.Results The properties and microscopic identification were described. Thin-layer chromatography method for chlorogenic acid in Leaf of Chinese Holly was formulated. Check items temporarily required that the moisture in Leaf of Chinese Holly should be less than 13%, total ash less than 13%, and acid-insoluble ash less than 5%. Content determination method for chlorogenic acid in Leaf of Chinese Holly was confirmed. It temporarily required that the content of chlorogenic acid should be more than 0.60%.Conclusion The established method can be used for the formulation of quality control of Leaf of Chinese Holly.
