  • US Pat. No. 4,774,229 claims a method for the treatment of tumors of the skin of mammals.
  • the tumors are treated topically with a novel mixture of a plant extract of the family Zygophyllaceae and a non-alkaline metal halide.
  • this invention is based on the idea that, depending on the particular concentration, highly cytotoxic salts of antimony, cadmium, copper and zinc can be converted into complexes with phenolic compounds and thus better applied for the desired applications.
  • a dry extract of plant parts of guaiac should be produced, which should be suitable for the supportive treatment of rheumatic complaints in accordance with Commission E's monograph.
  • the addition and concentration must be such that during this process, such an alcohol and water concentration is maintained that neither the gum arabic precipitates nor separate the plant extractives contained in the extract.
  • the dry extract can be obtained either by conventional spray drying, belt drying or paddle drying of the spissum extract, in particular the post-concentrated spissum extract.

  • the weight ratio of drug to extractant mixture was 1: 7.
  • the drug thus extracted was separated by stratified filtration.
  • the remaining portion of the fluid extract was continuously added to the evaporator until the entire amount of the fluid extract was drawn in and concentrated.
  • the spissum extract thus obtained had a light brown color, was free-flowing and of homogeneous consistency.
  • This spissum extract was concentrated under vacuum (300 mbar to 20 mbar) and elevated temperature (40 0 C to 55 ° C) to a dry matter content of 45% to 55%.
  • the resulting concentrated spissum extract (2 kg with 50% dry matter content) had a light brown color, was thick-flowing and of homogeneous consistency.
  • This post-concentrated spissum extract was dried in a dryer under vacuum at a pressure of 150 mbar to 10 mbar and a temperature of 40 ° C to 55 ° C.
  • the dry extract prepared according to the invention was dissolved in 90 v / v% ethanol and diluted so that a maximum concentration of 1 v / v% ethanol in Test system resulted.
