Abstract

OBJECTIVE To select an optimal extraction techno logy for Yinghuhuang capsules. METHODS An orthogonal test method based on the content of anth raquinones was used to determine an optimal technology. RESULTS Solvent was a marked factor influencing the extraction obviously (P 0.05). Time of extraction and the amount of solvent had no obvious effect.CONCLUSION The optimal condition is to extract using 4 times am ount of alcohol (95%) for 2 hours.
