Figure Lengend Snippet: ( a ) The UV-visible spectrum of PTX solution and ( b ) the calibration curve for amounts of PTX dissolved in ethanol solutions ranging from 25 ppm to 150 ppm.

Article Snippet: Due to the hydrophobicity of PTX (Sigma-Aldrich, St. Louis, MO, USA), we dissolved it in an alcohol solution with a concentration range of 25 to 150 ppm, measured its absorbance using UV-Visible spectroscopy (Hitachi U-3010, Tokyo, Japan), and used the resulting absorbance values to create a calibration curve that adhered to established standards.
