Отримання й хімія
Спосіб отримання
The oil is obtained by steam distillation after maceration in water of the comminuted dried roots. Since the oil contains water-soluble components and has a specific gravity similar to that of water, it is then recovered from the distillation waters by extraction with solvents. The yield is approximately 0.7%. In another study, 400 g of coarsely powdered roots were steam-distilled with a Clevenger system for 3 h, and the essential oil yield was 3 %. Two earlier studies reported that hydro-distillation of the roots yielded oil at 0.23% and 0.89% (v/w).
