Method of preparing biologically active derivatives from Calotropis Gigantea flowers
United State Patent
A method of preparing biologically active derivatives from Calotropis gigantea flowers includes obtaining fresh Calotropis gigantea flowers, drying the fresh flowers, soaking the dried flowers in natural oil, eg., almond oil, and burning the oil-soaked flowers to provide flower ash, the flower ash including the biologically active derivatives. The flower ash can be toxin-free.
A novel efficient eco-friendly on “ionic liquid” method has been developed for the synthesis of multifunctionalized isoxazolidines through a nitrone 1,3-dipolar cycloaddition reaction. The low…
