Impatiens balsamina (syn. terada; garden balsam; garden jewelweed, sanskrit: “dushparijati”) belongs to the family balsaminaceae. This species has been used as indigenous traditional medicine in Asia for rheumatism, fractures and other ailments. In Korean folk medicine this impatiens species is used as a medicine called bong seon wha dae for the treatment of constipation and gastritis. It has been used for disease and skin afflictions. Juice from the leaves is used to treat warts and snakebite and the flower is applied to burns. Literature survey revealed that lawsone, a naphthoquinone, isolated from the methanolic extract of Impatiens balsamina leaves possesses potent antioxidant and anticancer activity [1] but it showed poor oral bioavailability. Hence, it was thought worthwhile to form a herbomineral complex of lawsone with zinc in order to improve the bioavailability and therapeutic activity of the phytoconstituents. The current research article deals with formation of herbomineral complex of lawsone and zinc, confirmation of formation of lawsone-zinc complex through physical properties and spectral analysis like UV- spectroscopy, IR, NMR, mass spectroscopy. It was prepared with an intention to increase bioavailability and bioactivity of lawsone.
