Micelle-Mediated Extraction Used in Analysis of Herbal Remedy

Researchers from Fourth Military Medical University (Shanxi, China) have developed a method for separating and determining hydrophobic compounds in Cnidium monnieri, an herbal remedy. The method is based on micelle-mediated extractionand cloud-point preconcentration followed by high performance liquid chromatography with photodiode-array detection. A nonionic solvent, Genapol X-080, was used as the extraction solvent. Cnidium monnieri is a leafy annual plant that grows in China and is used in traditional Chinese medicine for skin problems and as an aphrodisiac.
