    摘要: The use of bicyclic carbohydrates for the treatment of parasite infections is described. Different bicyclic carbohydrates have been tested in vitro against a number of protozoa. These compounds also have been screened against viruses, tumors, bacteria and fungi. Compound A1, a thiophenyl-containing bicyclic carbohydrate possessed significant activity against Trypanosoma brucei rhodiense, a parasite that causes the lethal sleeping sickness. Compound A2 and Compound A3, bicyclic carbohydrates with halogen containing aryl groups, possessed significant activity against Leishmania donovani, a parasite that causes leishmaniasis. Bicyclic carbohydrates in general, and Compound A1, Compound A2 and Compound A3 more specifically, could be possible treatments for the sleeping sickness and leishmaniasis in the future.

    摘要: Conversion of crude lecithin is performed by incubating the lecithin with a lipase-phospholipase mixture in a water/polyol environment. The incubation is carried out at about 40-50.degree. C. and a pH of about 7 to about 8 while stirring continuously. The reaction simultaneously produces lysolipid, lysophospholipid, monoglycerides, and diglycerides. The conversion rate of lecithin is more than 80% based on the ratio of LPC/PC (lysophosphatidylcholine/phosphatidylcholine). Calcium chloride can be added to the reaction mixture to capture released fatty acids.

    摘要: A method for improving the performance of enzymes used in animal feeds by the use of surfactants. Lecithin and/or lysolecithin is added to an animal feed including an exogenous enzyme to boost the performance of the enzyme so that a desired level of performance can be maintained while reducing the amount of exogenous enzyme that must be included in the animal feed. Preferably, the surfactant includes lyso-forms of lecithin.

    摘要: This invention relates to the in situ process for converting non-free-form xanthophylls to free xanthophylls in the biological material of the plant. The method, more particularly, relates to a method that would liberate xanthophylls by transesterification of acyl-xanthophylls in plant materials which is used as a natural food colorant.
