    • Abstract


      The flower petals ofHibiscus sabdariffa contain hibiscitrin as the main component. Gossypitrin is present to a smaller extent. Besides these two, a small amount of a new compound named sabdaritrin has also been isolated. On boiling with dilute sulphuric acid it yields a new hydroxyflavone called sabdaretin.
