用紫外分光光度法测定了（+）-松萝酸在水、乙醇、丙酮、乙酸乙酯和正己烷中的溶解度。得到的结果导致的溶解度顺序：乙酸乙酯丙酮正己烷乙醇水。用Apelblat方程、λh方程和理想模型对溶解度进行了关联。结果表明，这三个模型与实验数据吻合较好。
Using ultraviolet spectrophotometry, the solubility of (+)-usnic acid in water, ethanol, acetone, ethyl acetate and n-hexane were measured at temperatures from (278.15 to 338.15) K at atmospheric pressure. The results obtained led to the solubility order: ethyl acetate > acetone > n-hexane > ethanol > water. The solubility values were correlated with the Apelblat equation, the λh equation and the ideal model. The results showed that these three models agreed well with the experimental data.
