Application(s) Curcumin , commonly called diferuloylmethane, is a polyphenol derived from the rhizome of the herb Curcuma longa or the Indian dietary spice ‘turmeric’.1Traditionally, turmeric is being used to treat many ailments and curcumin was identified as the active principle of turmeric. It was found to show a plethora of pharmacological properties including anti-inflammatory, anti-oxidant, anti-microbial and anti-cancer activities. Commercial curcumin, in general, is impure and may contain several derivatives of curcumin.1Further, it is available in powdered or microcrystalline state. Crystallization, a well-known purification technique, can be used to isolate pure curcumin2,3 and also to produce macroscopic crystalsfor storage and different purposes. Big crystals are comparatively more stable (in other words less reactive) than small crystals and powdered form because of less surface area.Hence, there is a need to optimize the conditions to grow large sized crystals of curcumin for various purposes.
