摘要
丹参采用醇提工艺,可将有效成分丹参酮Ⅱ_A 提取90%以上。但经制稠膏干燥过程,丹参酮降解甚多。减压处理过程虽可减少降解,但大生产过程的湿热接触时间较实验室长,尽管采用减压处理工序仍无法有效保留丹参酮类有效成分。采用超临界 CO_2流体萃取(SFE—CO_2),加乙醇作为夹带剂,萃取压力20Mpa、温度40℃,得结晶状物及深红色夹带剂液,丹参酮Ⅱ_A 含量高,可直接用于制剂生产,优于乙醇提取工艺。
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.
