  • Publication number: 20040077883
    Abstract: A method of isolating terpene trilactones from Ginkgo biloba plant material or extract comprising the steps of suspending the plant material or extract in either water or an aqueous solution of an oxidation reagent; extracting the terpene trilactones using an acceptable extraction agent; separating the organic layer from the aqueous layer; washing the organic layer with an acceptable aqueous salt or hydroxide solution, which may be an alkaline solution; and drying the organic layer to form a dried extract containing terpene trilactones. Further purification by treatment with or filtration over activated charcoal, by treatment with or filtration over alumina and by recrystallization with an acceptable solvent or solvent mixture leads to extracts with a content of terpene trilactones higher than 50%. Unwanted levels of ginkgolic acids are reduced to acceptable levels by reversed phase chromatography.

  • Patent number: 6420165
    Abstract: A biologically pure culture of a microorganism is provided designated SH2A and deposited under ATCC Accession No. 55926, or a mutant derived therefrom. Further provided is a biologically pure culture of a microorganism designated SH2B and deposited under ATCC Accession No. 202050, or a mutant derived therefrom. A method of degrading an organic material such as sludge is carried out by treating the organic material with an effective, degrading amount of either SH2A or a mutant derived therefrom, or SH2B or a mutant derived therefrom. The microorganism designated SH2A or a mutant derived therefrom, or SH2B or a mutant derived therefrom, is grown by culturing the microorganism at a temperature and in a medium effective to promote growth of the microorganism.
