Introduction. The growing interest in secondary metabolites of plants has directed attention to methods for their extraction. Natural products are extracted by conventional methods such as Soxhlet and room temperature solvent extraction, 1-7 or by ultrasound, 8-14 microwaves, 15-18 supercritical solvents 19-30 or other methods. 31-34 In this paper a new method is developed to extract alkaloids With plant material, the primary extraction is usually effected with organic water-immiscible solvents after the liberation of the alkaloidal bases from their salts by treatment with a mineral base. Ammonia is sufficiently basic to liberate most of the common alkaloids without much risk of undesirable reactions. In addition, as ammonia is volatile, it can easily be removed afterwards.

Phenolics can be extracted from fresh, frozen or dried plant samples. Usually before extraction plant samples are treated by milling, grinding and homogenization, which may be preceded by air-drying or freeze-drying. Generally, freeze-drying retains higher levels of phenolics content in plant … With plant material, the primary extraction is usually effected with organic water-immiscible solvents after the liberation of the alkaloidal bases from their salts by treatment with a mineral base. Ammonia is sufficiently basic to liberate most of the common alkaloids without much risk of undesirable reactions. In addition, as ammonia is volatile, it can easily be removed afterwards.
To isolate alkaloids from plants, the dried and powdered plant material is extracted with pet ether (or hexane, colemans etc.) first. This removes fats, oils, terpenes, waxes etc. This extract is discarded. The material is now subjected to an alcohol extraction, eg with methanol or ethanol. The extract is evaporated to leave the crude alkaloids The general methods of extraction of alkaloids from the plant sources solely depend upon the purpose and scale of the operation (e.g., pilot scale or commercial scale).It is also based on the quantum and bulk of the raw material to be employed in the operation. Of course, for research purposes column chromatography using ion-exchange resins have been used successfully and effectively to strip

Alkaloids ppt 1. Presenter: MAHEYA MIDHAT KHAN Department Of Pharmacy Jinnah University For women, Karachi. 2. the term “alkaloid” (alkali-like) is commonly used to designate basic heterocyclic nitrogenous compounds of plant origin that are physiologically active. Keywords: alkaloids, extraction, sonication, surfactants, Mayer reagent Introduction The growing interest in secondary metabolites of plants has directed attention to methods for their extraction. Natural products are extracted by conventional methods such as Soxhlet and room temperature solvent extraction,1-7 or by
