  • Patent number: 5756773
    Abstract: The invention discloses novel triterpene derivatives of azadirachtin of the formulae 2 to 11 of the drawings and a process for isolating new triterpene derivatives of azadirachtin from the various parts of the neem plant (Azadirachta indica A-Juss), which process comprises grinding the parts of the neem plant to get a powder, extracting the powder with a binary immiscible solvent consisting of one polar and another non-polar solvent in a ratio of 1:2 to obtain an extract, filtering the extract to get a filtrate having two layers, one layer containing lipids and the other layer containing the new triterpene derivatives of azadirachtin and water soluble constituents including sugars, separating the layers by known methods, concentrating the layer containing the new triterpenes of the formulae 2-11 including derivatives of azadirachtin and water soluble salts, treating the resultant concentrate with a polar solvent and if necessary, warm the concentrate having the solvent, and filtering/decanting the resultant s

  • Patent number: 5744070
    Abstract: Described are novel reversible photochromic naphthopyran compounds, examples of which are 3H-naphtho?2,1-b!pyrans having an acyl or aroyl oxy-bearing substituent at the number 6 carbon atom and certain substituents at the 3-position of the pyran ring. Certain substituents may also be present at the number 5, 7, 8, 9 or 10 carbon atom of the naphthopyran. These compounds may be represented by the following graphic formula: ##STR1## Also described are polymeric organic host materials that contain or that are coated with such compounds. Optically clear articles such as ophthalmic lenses or other plastic transparencies that incorporate the novel naphthopyran compounds or combinations thereof with complementary photochromic compounds, e.g., certain other naphthopyrans, benzopyrans, and spiro(indoline)type compounds, are also described.
