Biological Activity

Additional Infomation

(-)-quinic acid is the (-)-enantiomer of quinic acid. It is a conjugate acid of a (-)-quinate. It is an enantiomer of a (+)-quinic acid. Quinic acid has been reported in Camellia sinensis, Cuscuta reflexa, and other organisms with data available. An acid which is found in cinchona bark and elsewhere in plants. (From Stedman, 26th ed)

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
