Salvianic acid A sodium
Salvianic acid A sodium is Liangxue Huoxue Tiaojing, removing blood stasis and relieving pain, carbuncle, heart Chufan, yangxueanshen. English name Salvianic acid A sodium and the synonym B - (3, 4 dihydroxy phenyl lactic acid), D (+) B (3, 4-Dihydroxyphenyl) lacticacid salvianic acid A, phenolic aromatic acids, brown yellow powder or yellow powder. Salvia miltiorrhiza could obviously inhibit the aggregation of platelet, and increase the fluidity of platelet membrane, which indicated that it was effective for coronary heart disease.
Chemical name: Propanoic acid, 3-(3, 4-dihydroxyphenyl)-2-hydroxy-
Plant origin: Labiate Salvia miltiorrhiza Bge. and the root of Salvia przewalskii.
Content specifications: >70%;>90%;>98% Thin layer identification of only one spot, as a single ingredient.
Physical properties: white long needle crystal, melting point 84 to 86 degrees C, density 1.546.
In the ethanol can not be measured by the rotation, FeCl3 reaction was yellow green.
Haoxiang Bio Extraction process: Salvia miltiorrhiza, crushing, adding 12 times amount of water, soak overnight, decocting two times, each time 2h. The extract was concentrated to the density of 1.3, plus 70% ethanol precipitation, and recovered ethanol. Twice with ether extraction, aquifer using saturated salt water precipitation, salting out filtration, the filtrate is placed by the white precipitate in water recrystallization Danshensu content is about 98%.
