Physical Property: white needle crystalline (recrystallization by dilute ethanol or dilute
acetic acid), M.P.: 236-237℃, freely soluble in hot water,
soluble in hot ethanol, insoluble in aether; turn to brown when mixing with
ferric trichloide, recover by magnesium and hydrochloric acid with red color;
without precipitation by adding CO2 into aqueous alkali; while hydrolysis after
adding 2% hydrochloric acid or sulfuric acid, it will generate hesperitin,
glucose and rhamnose each per molecule.

Indications: For the treatment of capillary fragility and over high protein
permeability in plasma. Therefore, it is used to be known as vitamin P or vitamin
