[Chemical changes of compatibility for shaoyao decoction].

OBJECTIVE

To probe the regular patterns of interactions among chemical components in Chinese medicinal complex prescriptions.

METHOD

The active components of Rhubarb, Coptis root and Baikal skullcap root in different patterns of compatibility were determined by TLC-scanner.

RESULT

The berberine content in Coptis root can be decreased obviously by Rhubarb, Baikai skullcap root and Licorice root, especially by Rhubarb. Coptis root can also decrease the contents of acid components.

CONCLUSION

The acid components can affect each other, thus reducing the contents of effective components.
