Embodiment 1
[0024] Example 1 Preparation of tanshinone extract and total phenolic acid extract from Danshen.
[0025] Take 200kg of Danshen decoction pieces, add 2000L of 85% ethanol solution, soak at 80°C for 1.5 hours, collect the extract, recover the ethanol, concentrate and dry to obtain tanshinone extract containing tanshinone ⅡA; add 1600L of water to the dregs, soak at 80°C After 1 hour, collect the extract, let it cool, put it directly on the column through macroporous resin D-101 (300L), wash with water until the effluent is colorless, and then use 20% ethanol solution (700L) to elute at a flow rate of 1.0 BV / h , collect the eluate, spray dry after evaporating ethanol to obtain the total phenolic acid extract of Salvia miltiorrhiza containing salvianolic acid B.
[0026] The content of tanshinone Ⅱ A in the tanshinone extract was determined to be 8.7% by high performance liquid chromatography. The yield of salvia miltiorrhiza extract was 1.2%, the total phenolic acid content of ...
Embodiment 2
[0027] Example 2 Preparation of tanshinone extract and total phenolic acid extract from Salvia miltiorrhiza.
[0028] Take 200kg of Danshen decoction pieces, add 1600L of 85% ethanol solution, soak twice at 75°C for 1 hour each time, collect the extract, recover the ethanol, concentrate and dry to obtain a tanshinone extract containing tanshinone ⅡA; add 2000L of water to the dregs, Soak twice at 75°C for 1 hour each time, collect the extracts and combine them, let them cool, and put them directly on the column through macroporous resin D-101 (340L), wash with water until the effluent is colorless, then use 30% ethanol solution ( 550L) was eluted at a flow rate of 1.2 BV / h, the eluate was collected, and after the ethanol was evaporated, it was spray-dried to obtain the total phenolic acid extract of Salvia miltiorrhiza containing salvianolic acid B.
[0029] The content of tanshinone Ⅱ A in the tanshinone extract was determined to be 9.6% by high performance liquid chromatogra...
Embodiment 3
[0030] Example 3 Preparation of Tanshinone Extract and Total Phenolic Acid Extract from Salvia Miltiorrhiza.
[0031] Take 500kg of Danshen decoction pieces, add 4500L of 90% ethanol solution, soak twice at 75°C for 1.5 hours each time, collect the extracts and combine them, recover the ethanol, concentrate and dry to obtain the tanshinone extract containing tanshinone ⅡA; add 3000L of water to the dregs , soaked twice at 75°C for 1 hour each time, collected the extracts and combined them, concentrated them properly and let them cool, put them on the column with macroporous resin D-101 (800L), washed them with water until the effluent was colorless, and then used 40% The ethanol solution (1000L) was eluted at a flow rate of 1.2 BV / h, the eluate was collected, and the ethanol was evaporated and then dried by microwave to obtain the total phenolic acid extract of Salvia miltiorrhiza containing salvianolic acid B.
[0032] The content of tanshinone Ⅱ A in the tanshinone extract w...
