Screening of the Active Fractions of Antipyretic Analgesics Powder by Molecular Distillation / 中国药房

ABSTRACT

OBJECTIVE: To study the active fractions from Antipyretic analgesics powder.METHODS:The active fractions were extracted from Antipyretic analgesics powder by supercritical-CO2 fluid extraction technique,separated and purified by molecular distillation(MD) technique.The active fractions were selected with the analgesic effect as index.RESULTS: The active fractions obtained showed remarkable analgesic effect.CONCLUSION: The result serves as a theoretic basis for the development of the active fractions-based new drugs.
