EXTRACT OF PERILLA FRUTESCENS VAR. ACUTA KUDO EFFECTIVE FOR PROPHYLAXIS AND THERAPY OF GASTRIC ULCER, ITS USE AND PROCESS FOR OBTAINING BERBERINE FROM THE EXTRACT
EXTRACT OF PERILLA FRUTESCENS VAR. ACUTA KUDO EFFECTIVE FOR PROPHYLAXIS AND THERAPY OF GASTRIC ULCER, ITS USE AND PROCESS FOR OBTAINING BERBERINE FROM THE EXTRACT
PROBLEM TO BE SOLVED: To confirm effects such as antimicrobial activity, suppression of uresase activity, intragastric fixability and interleukin-8 generation, or the like, against Helicobacter pylori which is a pathogen of gastritis, gastric ulcer and duodenal ulcer and then to identify and obtain an active ingredient against Helicobacter pylori from Perilla frutescens var. acuta KUDO which is a food material. SOLUTION: This extract comprises one or more kinds of hot-water extracts produced by adding water in an amount of 5-20 times weight based on the Perilla frutescens var. actua KUDO, carrying out hot-water extraction thereof at 80-120 deg.C for 6-15 h and carrying out vacuum concentration of the filtrate under 40-70 cmHg and a solvent extract produced by adding 50-70% ethanol in an amount of 5-20 times weight based on the amount of the crude drug material, then extracting at 50-90 deg.C for 4-8 h and carrying out vacuum concentration of the filtrate under 40-70 cmHg, and has the effects such as the antimicrobial activity and the suppressions of urease activity of Helicobacter, of gastric epithelial cell fixability and suppression of interleukin-8 purification against the Helicobacter pylori. Besides, a berberine becomes a main active ingredient in the extract of the Perilla frutescens var. acuta KUDO by dividing a water-soluble layer obtained therefrom using an organic solvent such as chloroform and an XAD-7 column chromatography and a silica column chromatography and separating the main active ingredient by using a preparative thin layer chromatography(TLC).
