Significance of Crude extract
Crude extract refers to unrefined preparations obtained from plants that contain a mixture of various natural compounds. These extracts are derived through methods such as solvent extraction or maceration, and they may exhibit significant biological activities, including antibacterial properties. Crude extracts are often subjected to initial assessments for their therapeutic potential, as they have not undergone any purification processes. They can provide concentrated solutions that may be further analyzed for their medicinal benefits or bioactivity.

(1) This is the concentrated extract remaining after the majority of the solvents have been removed from the mixture.[1] (2) Crude extract is an extract that has not been purified, and high flavonoid and phenolic content have been reported in the crude extract of P. betle.[2] (3) The crude extract was prepared using a maceration method, and galls were extracted with a solvent at a specific ratio, highlighting a key step.[3] (4) These are the substances obtained from the plant material using different solvents, and the antimalarial and toxicological activities of these extracts were investigated.[4] (5) Unrefined substances that were not resuspended in an aqueous solution, instead being reconstituted in dimethyl sulfoxide, ethanol or methanol, thus confounding the studies.[5]
