If we talk about the medicinal field, an extract is classified as the substance obtained from the plant that has passed or has undergone chemical procedures, applied with the purpose of achieving the maximum purification of the same where the obtaining of the most chemical bases is achieved. important or the essence of that plant.
In pharmacology the extract of medicinal plants is widely used, these can be different physical characteristics, they can be differentiated into solid, liquid and semi-solid, known as dry extracts, fluid extracts, dense extracts respectively; Plant extracts can also be classified according to their composition, allowing us to define three types of extracts, which are: adjusted extracts, they are processed so that an adequate tolerance is generated in terms of the content of their constituents and that it is enough for them to exercise therapeutic activityOn the other hand, standardized extracts can be defined in which a progressive adjustment of the amount of the extract's constituents is made to achieve the desired tolerance by adding inert material followed by mixing with batches of extracts.
As the last type of extract, the quantified extract is mentioned, which differs from the standardized ones in that the aggregation of the extra materials is carried out in a specific and known quantity, allowing the quantification or counting of the percentage of each constituent that forms the extract, A primary component for the application of the methodology used for the preparation of the extract is water, this must comply with defined health indices, failure to comply with them will produce extracts with a non- specific or unknown purification.
