METHOD TO PREPARE AN IMPROVED STORAGE STABLE NEEM SEED EXTRACT |
摘要 |
A process for the production of stable azadirachtin solutions comprising extracting ground neem seeds with a solvent having azadirachtin solubility to produce an aqueous-containing azadirachtin extract solution and then adding an effective amount of 3-4 Angstrom molecular sieves to selectively remove water from the extract to yield a storage-stable azadirachtin solution having less than 5% water by volume. |
