Abstract:
The tanshinone ⅡA,an effective component of Radix Salviae Miltiorrhizae(RSM)can be extracted up to 90% in alcohol,but mostly decomposed in the later concentrating and drying procedures.Although reducing-pressure concentrating processes can reduce the decomposi- tion in experiment,but it can not preserve effectively the tanshinone during the large scale production because of the extended time of tanshinone in dampness and heat.Supercritical carbon dioxide extraction(SFE-CO_2)of RSM can give crystalline substance and dark red modifier when the alcohol is used as modifier at extraction pressure of 10 Mpa and the tem- perature at 40℃.The SFE-CO_2 technology can get higher concentration of tanshinone and be used during preparation production directly.The SFE-CO_2 technology is superior to the alco- hol-extraction technology.
