| Abstract
|
| [Objective] To study the optimizing technics of the extraction of Rad ix Salviae Miltiorrhizae with microwave. [Methods] Taking Tanshinone IIA(lipo soluble component),Radix Salviae Miltiorrhizae elements(water-soluble component) and catechu aldehyde as the indexes,a method of uniform experimental design was applied to optimize the technics of microwave extraction and compared with the traditional technics. Radix Salviae Miltiorrhizae was extracted for 30 minutes with of 95% alcohol of 6-fod amount and microwave power of 320 w first, than the drug residue was extracted twice with water of 12-fold volume and 320 w microwave. [Results] The extracted amount of three components is equal or superi or to that extracted by the method being used now. [Conclusion] The extract of Radix Salviae Miltiorrhizae ketone IIA with microwave is easy, but a relative longer time is needed for xtracting Radix Salviae Miltiorrhizae elements and catechu aldehyde. |
