Use

Hematoxylin recrystallises from H2O (as trihydrate) in white-yellow crystals which become red on exposure to light and then melt at 100-120o. It has been recrystallised from Me2CO/*C6H6. It has been recrystallised as well from dilute aqueous NaHSO3 until colourless and is soluble in alkali, borax and glycerol. Store it in the dark below 0o.
