title: Identification of prescription drugs in adulterated Chinese herbal medications.
abstract: Analytical difficulties involved in the detection of a wide range of suspected polar and nonpolar drugs in botanical matrices have been solved by adopting a multipronged approach. Preliminary screening of Chinese herbal medications can be accomplished by a combination of thin-layer chromatography and gas chromatography/mass spectrometry and/or the employment of liquid chromatography/mass spectrometry as a probe introduction technique.
