2.4. Preparation of Plant Extracts for HPLC Analysis The methanolic and n-hexane–Et2O (1:1) extracts were prepared by dissolving 2.5 g of dried powdered root bark into 100 mL of organic solvents, and afterwards macerated for 72 hours at 25 °C. Both extracts were concentrated under reduced...
of plant materials by developing a new no-waste extraction method for eucalypt leaves and by investigating the phytochemical and pharmacological properties of eucalypt extracts and their 3D-printed dosage forms. The present extraction method enabled us to prepare both hydrophobic soft extracts and ...
