Course Goal / Objective
By the end of this course, students explain the fundamental principles of the main extraction technologies used for medicinal and aromatic plants, the process variables involved, the equipment employed, and the criteria related to yield and quality.
Course Content
This course includes information on the preparation of herbal drugs for extraction in medicinal and aromatic plants; solvent selection; classical extraction methods (maceration, infusion, decoction, percolation, and Soxhlet extraction); modern extraction methods (ultrasound-assisted extraction, microwave-assisted extraction, pressurized liquid extraction, supercritical fluid extraction, and enzyme-assisted extraction); process optimization; standardization of extracts; and approaches to obtaining essential oils and oleoresins.
Course Precondition
No prerequisities.
Resources
The course notes are sent to the e-mails of the students.
