Potassium bromide (KBr) is a salt, widely used as an anticonvulsant and a sedative in the late 19th and early 20th centuries, with over-the-counter use extending to 1975 in the US. Its action is due to the bromide ion (sodium bromide is equally effective). Potassium bromide is used as a veterinary drug, as an antiepileptic medication for dogs. Webfrom methanol fraction was the main challenge of the research study. This study's goal was to separate andrographolide from A. paniculata leaves and analyze the bioactive components of the methanol fraction. Using column chromatography and gradient elution with several mobile phases, the isolation was carried out. law lane canton ny application
