They are exhausted with water, and the residue is treated with a mixture of equal parts of alcohol and water, containing one per cent. of caustic potash; on adding HCl, impure hesperidin separates out. It crystallizes from water, alcohol, or dilute acids in white, microscopic needles. It is insoluble in ether; it is soluble in dilute potash, and the solution becomes orange yellow on standing; when this solution is evaporated to dryne , and the residue treated with dilute sulphuric acid, it turns red, then violet. Fused with caustic potash, hesperidin yields pro toc a tec huic acid. hěs-per-id-1-ŭm, s .
