【Abstract】 Objective:To observe and study microscopic characteristics of dissolving-out characteristics of effective compositions from Taraxacum mongolicum Hand Mazz.. Methods: Taraxacum mongolicum Hand Mazz. was porphyrized into cell-level ultramicro-powder; the dissolving characteristics of its compositions were observed and studied with the method of thin-layer chromatography.Results: The findings indicate that thin-layer chromatography of effective compositions are remarkably improved, after it is ultramicro-porphyrized, and the representive composition, caffeic acid, is rapidly dissolved out from methanol and water. Conclusion:The findings indicate that dissolving-out characteristics changes greatly after it is ultramicro-porphyrized, it can simplize the extracting process.更多还原
