  • An Improved Method for the Extraction and ThinLayer

    In contrast, the method described here is fast, reliable, and does not require a separate extraction or drying step. The student grinds the fresh spinach leaf with sand and drying agent followed by extraction directly into acetone. The sand helps to lyse the cells and acts as an inert material, which improves the extraction process.
