Nutmeg traditionally has been used as an abortifacient. Allow the solids to settle in the centrifuge tube for a minute. And the solvent will evaporate into gas so the pressure inside will increase also. Structure-activity studies of the carcinogenicities in the mouse and rat of some naturally occurring and synthetic alkenylbenzene derivatives related to safrole and estragole.

Narasimhan B, Dhake AS. The initial mixture, containing the solute dissolved in the carrier liquid, is mixed with the solvent. A significant part of the structure proof of many natural products is their degradation by chemical reactionsto simpler structures.


US Environmental Protection Agency. Do not let filter paper dry out. Too much pressure might cause the filter to leak or fall off. Cool the beaker in ice water for 10 min, with stirring, and collect the solid by vacuum filtration on a small Hirsch funnel.

Anticonvulsant activities of nutmeg oil of Myristica fragrans. Boiling stones were then added and the condenser was inserted with the water entering from the bottom into the neck of the round bottom flask and clamped in place.
