[Chemical contrast research on Buyang Huanwu complex ultramicro powder soak and traditional decoction].
OBJECTIVE
To study the chemical composition of Buyang Huanwu complex ultramicro powder soak and traditional decoction.


METHODS
Extractive determination, heavy metal and arsenic determination, TLC and HPLC were used to analysis the chemical composition.


RESULTS
The extract of Buyang Huanwu complex ultramicro powder soak was higher than that of traditional decoction. The lamellar spot of Buyang Huanwu complex ultramicro powder soak was clearer than that of traditional decoction. Astragalin in Buyang Huanwu complex ultramicro powder soak was correspond with the traditional decoction.


CONCLUSIONS
The way of soaking ultramicro powder not only can avoid losing active component, but also can release it quickly.
