Hydrodistillation is a method described by the European Pharmacopoeia for volatile oil extraction. The equipment used for hydrodistillation is the Clevenger apparatus (Abdellatif and Hassani, 2015), which has a long tube, at the end of which the vapor is condensed and recovered. The volatile oil is removed from the top of the hydrosol.
extraction method were to be chosen to extract a some specific constituent like germacrene D and αcarophyllene, steam distillation with the apparatus described by the British Pharmacopedia should be used. However if an extraction method were to be used to extract carophyllene, water distillation should be used.
· While extracting essential oil by hydrodistillation using Clevenger apparatus, the water boils at 100°C that cause to ascend the vapour mixture (steam and extractible oil) and yield essential oil, but prolonged heating at high temperature may cause changes or .
Extraction of essential oil can be done using various methods, although some are not commonly used today. Nowadays, distiller plays an im .
Automated extraction methods using the Soxtec have gained widespread acceptance and have a number of regulatory agency approvals worldwide. The Soxtec method has been used on literally hundreds of different sample types for many extracts. For our purposes, this discussion will be limited mainly to crude fat extraction.
Soxhlet extraction apparatus. Method: Weigh into an extraction thimble 23 g of the dried sample (residue from dry matter determination can be used). Place the thimble inside the soxhlet apparatus. Place a dry, tared solvent flask in position beneath, add the required quantity of .
preserved using this method. However, freezedrying is a complex and expensive methods of drying compared to regular air drying and microwavedrying. Thus, the use is restricted to delie, heatsensitive materials of high value. Extraction methods Extraction is the separation of medicinally active portions of

Method of extraction using succellence apparatuse are a largescale manufacturer specializing in producing various mining machines including different types of sand and gravel equipment, milling equipment, mineral processing equipment and building materials equipment.
Countercurrent Extraction Craig Apparatus. Theory. A method of multiple liquidliquid extractions is countercurrent extraction, which permits the separation of substances with different distribution coefficients (ratios). A clever design known as Craig apparatus is used for this purpose (Lyman C. Craig, 1943). Lyman C. Craig,
Solvent extraction method belongs in chemical methods, and is the most popular method for separation of oil from soybeans, mainly because of the method's high extraction efficiency (over 99%) as well as its capability to handle large quantities. Soxhlet method It is a method of extraction in which the soxhlet extractor is used.
· The general methods of extraction of alkaloids from the plant sources solely depend upon the purpose and scale of the operation (, 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 ionexchange resins have been used successfully and effectively to .
method of extraction using succellence apparatus. Apparatus Used For Soxhlet Extraction Method. PROCEDURE: First of all, rinse all the glass apparatus by petroleum ether and dry it in the oven at 102°c and af

Cold extraction method with methanol solvent gave % yield whereas % yield was observed for ethanol solvent. All the values have significant difference. Recorded yield of black cutch extract was % with soxlet extraction using methanol solvent this was followed by cold extraction method using methanol solvent (%).
Filtration is the method of separation in which impurities are removed from water by using a filter paper. (Image to be added soon) The solid impurity which we get on the filter paper is called residue and the water which passed through the filter .
· A Clevenger Apparatus is a tool used for essential oil extraction using steam. This technique uses temperature to separate the aromatic oil from an organic source. Organic compounds are separated using steam, so as not to degrade the essential oil. Essential oils are what is used for perfume, food, medicines or atomizers.
· Figure 1. Hydrodiffusion extraction apparatus. Hydrodiffusion (figure 1) consists of extracting the essential oil with steam that circulates through the plant material. At laboratory scale, we bring a few liters of water to a boil, and steam rises in a column containing the more or less finely ground plant. The vapor phase is then directed to a ...
· Some extraction methods, however, such as sublimation, expeller pressing and enfleurage are rarely used in current phytochemical investigation and will not discussed in this review. A brief summary of the various extraction methods used .
up. This problem can be overcome by using a multistage process. ¾The equipment needed for this method is a vessel for the drug, together with a circulating pump and spray distributors, and a number of tanks to receive the extracted solution. ¾The extractor and tanks are connected with piping and valves as
