Abstract: Provided are biologically active extracts from Aframomum aulocacarpus, Aframomum danellii, Dracaena arborea, Eupatorium odoratum, Glossocalyx brevipes and Napoleonaea imperialis which are suitable for use in treating fungal and protozoa diseases.

Abstract: Novel antiparasitic and antifungal compositions are disclosed. The antiparasitic and antifungal compositions are useful for human and veterinary therapy for the treatment and/or prevention of parasitic infection. Also disclosed are novel mechanisms of identifying antifungal and antiparasitic compositions by their biochemical action on lipid synthesis and/or metabolism and/or excretion.

Abstract: A method of preparing substantially purified alkaloids from seeds, stems, uit-rind and bark of a plant selected from Picralima nitida, Gongronema latifolia, Dorstenia multiradiata, Cola attiensis, Rothmania withfieldii and Desmodium gangeticum, for use in the treatment of protozoal diseases, comprising:pulverizing said plant;a first solvent, drying the extracted material and re-extracting the dried material with a different solvent;extracting a fresh sample of said plant with boiling water;filtering and concentrating the boiling water solvent extracts under reduced pressure;concentrating the dried extract to a gum and re-extracting said gum with an aqueous acidic HCl solution;filtering the acidic extract and making it alkaline to a pH of about 9 with a concentration NaOH solution;extracting the alkaline solution with dichloromethane;concentrating organic layers of the extracted alkaline solution to dryness under reduced pressure to obtain an alkaloid fraction; andseparating the alkaloid fraction by liquid chr

Abstract: A new compound, dioscoretine, as well as the process for making the same is described. According to a preferred embodiment, dioscoretine is derived from the tuber of Dioscorea dumetorum. Dioscoretine is a hypoglycemic agent and thus is useful for therapeutic treatment of conditions such as diabetes mellitus.
