Study on Preparation Technology of Effervescent Tablets of Alpinia oxyphylla
Alpinia oxyphylla was used as raw material,taking the disintegration time, brittleness and foaming amount of effervescent tablets as evaluation indexes, orthogonal test method was used to determine the optimal formula of the processing technology of effervescent tablet on the basis of single factor test.The results showed that the optimal formula for processing technology of Alpinia oxyphylla effervescent tablets was 10% of Alpinia oxyphylla powder, 45% of effervescent citric acid and sodium bicarbonate (mass ratio: 1.2:1),40% of lactose,2.25% of ste-via side,lubricant PEG 6000 at 3%, and adhesive at 90% ethanol. The prepared effervescent tablets had a smooth surface, clear soup color and rapid disintegration, meeting the quality standards.
