摘要
研究了浓度和压力对胭脂红酸荧光强度的影响，探讨了在弱酸性水溶液中胭脂红酸分子的可能存在形式。
The concentration and pressure effects on fluorescence of carminic acid is studied,the results showed that dimer stacking of carminic acid was formed in weak acidic solution. The conclusion that carminic acid is stable in weak acidic solution is obtained in view of molecular structure.
