The principle involved in this technique is similar to the maceration. In both these methods samples are soaked in boiled or cold water. The advantage of this method is the shorter maceration period. Decoction is employed particularly for extracting the heat stable constituents and also for extraction from plant materials that are hard such as roots or barks.

Leaves of C. grandifolia O. Berg were collected in September 2013 in Teutônia (29° 26′ 52″ S, 51° 48′ 21″ W), Southern Brazil. The material was authenticated by Prof. Dr. Elisete M. de Freitas, a botanist from the University of Vale do Taquari – Univates. For further analysis, leaves of C. grandifolia were dehydrated in a circulating air oven at 38ºC for 24 hr. After drying, plant material was crushed with pestle and ground with a blender. An aqueous extract was then prepared by decoction in water at 70°C for 120 min. This process was repeated twice, and resulting biomass combined, filtered using a vacuum system (Kitasato + vacuum pump), and dried in a rotary evaporator at 40°C. The resultant dried material was then solubilized in ultrapure water at a concentration of 20 mg/ml.

Vernicia fordii seed extract had prepared by the decoction extraction method. The plant seeds were cleaned gently to eliminate dirt and dust, air-dried at room temperature. Five grams of seeds were mashed in a mortar and soaked with 50 mL of water and are gently boiled for 2 h at 70–75 °C using a water bath and cooled followed by filtration using a Buchner funnel and Whatman filter paper No. 1 and centrifuged for 10 min at 10,000 rpm. The filtrate had manipulated for the integration of ZnO and CuO NPs.
Antimicrobial evaluation of Tripleurospermum callosum (Boiss. & Heldr.) E. Hossain extracts using in vitro and in vivo Caenorhabditis elegans model against urinary system pathogens

To the best of our knowledge, all Tripleurospermum callosum compounds reported in the present study were detected by LC-MS/MS for the first time. The relative concentration of the compounds analysed within the extracts was highest in the infusion, less in the decoction, and the least in the ethanol extract.
