ABSTRACT
<p><b>OBJECTIVE</b>To investigate the representation methods of dissolubility property of total alkaloid extract from Peganum hamala in different solvents, and to investigate the evaluation method of the dissolubility property of extracts from traditional Chinese medicine.</p><p><b>METHOD</b>The dissolubility property of the whole extract and markers of harmaline and harmine, as well as the particle diameter distribution of the extract in different solvents were evaluated by precipitation method, solubility test, and the particle diameter test.</p><p><b>RESULT</b>Both the alkaloid extract and it's index ingredients had good solubility in absolute ethanol, 95% ethanol, and 80% ethanol, while the solubility in 60% ethanol was poor, and worst in water. The sequence of particle diameter of extract in solvents was in the following order water > 95% ethanol > 60% ethanol > 60% ethanol > 80% ethanol.</p><p><b>CONCLUSION</b>The extract has good solubility in the ethanol solution whose concentration is over 80%. The results between precipitation method and index components method have certain correlation. The particle diameter method can provide distribution information of the extract in different solvents. Combination of those three methods could reflect the dissolubility property of extracts from traditional Chinese medicine more comprehensively.</p>
