Abstract

PURPOSE:To obtain a thrombosis inhibitor having excellent safety, containing a 1, 2-dihydroxy-4-(2-hydroxyethyl)benzene derivative. CONSTITUTION:This thrombosis inhibitor contains a compound of formula I (R1 to R3 are H or acyl; R4 and R5 are H or short chain alkyl; R6 is H or short chain alkyloxy; Rham is rhamnose residue of formula II) and/or its salt as an active ingredient. The thrombosis inhibitor shows high blood platelet control ratio, excellent inhibitory effect on thrombosis and is effective for preventing and treating thrombosis. One or more of the thrombosis inhibitors are mixed to give a composition of medicine, food, etc. The mixed amount of the thrombosis inhibitor for a daily intake per adult is 1-1,000mg/kg calculated as the amount of the thrombosis inhibitor. The compound of formula I is obtained by extracting the whole plant of Stachys riederi of labiate plant with a solvent, filtering and purifying.

To each of these, 0.02 ml of 2 μM adenosine 5'2 phosphate monosodium salt (manufactured by Boehringer Mannheim Japan) was added as a platelet aggregation inducer, and after stirring for 7 minutes, a platelet aggregation measuring device (hematracer 601, manufactured by Nikko Bioscience Co., Ltd.) was used to measure the degree of platelet aggregation. In addition, the same operation and measurement were performed using a 2 μg / ml collagen solution (hormone Chemie Munich) as a platelet aggregation inducer.
