The samples’ weight losses were measured by laboratory balance with the readability 0.01g (Radwag, Radom, Poland) at ambient temperature 22 °C ± 0.5 °C and at relative humidity 62% ± 0.5%. The experiments were carried on thrice. 2.2. Methods 2.2.1. Attenuated Total Reflectance–Fourier...
The collected leaves were subjected to hot-air drying with forced air circulation (UFE 400, Memmert, Schwabach, Germany) at 50 °C such as to reach a final moisture content of 5–6% as measured using a moisture analyzer (Mac 210/NP Radwag, Radom, Poland). Dried leaves were ground using...
