Subcritical water extraction of horse chestnut (Aesculus hippocastanum) tree parts
Subcritical water extraction of horse chestnut (Aesculus hippocastanum) parts, such as seeds, seed shell, bark and leaves has been performed in a batch reactor at temperatures of 150, 200 and 250°C and extraction times of 5, 15 and 30 min. The obtained extracts were analyzed by spectrophotometric me...
