| Abstract: | Objective： To compare the physical properties of vacuum water extract and atmospheric water extract of Danshen. Method： The specifi c surface area, porosity, particle size, angle of repose, bulk density and tapped density, moisture absorption percentage of two water extracts were measured and compared. Result： The specifi c surface area and porosity of Danshen vacuum extract were greater than the atmospheric extract. Particle size distribution of the vacuum extract was more concentrated with less particle size distribution range. Angle of repose and bulk density of vacuum extract were less than atmospheric extract. But tap density and moisture absorption percentage were greater than the atmospheric extract. Conclusion： Danshen vacuum water extract is more stable than atmospheric water extract. |
