Extraction of phytochemicals from plants ppt


Plant extraction is a process that aims to extract certain components present in plants. The plant components of interest are then solubilised and contained within the solvent. The solution thus obtained is the desired extract. The solvent will eventually be eliminated to isolate the plant extract. If it is for the food industry, it is not necessary to separate it from the extract. If not, a second separation operation makes it possible to obtain a dry extract.

The origin of the extraction of active plant ingredients has been lost to time. The first extracts were essentially obtained through aqueous extraction or alcoholic fermentation, and according to procedures such as infusion, maceration, decoction and hydrodistillation. The simplicity of these procedures, as well as the tools, materials and heating methods of the time, meant that the extractor was a man of the arts rather than a scientist. Today, this activity calls upon the use of precise automatons and adapted materials.

It has benefited from advances in process engineering, phytochemistry and analytics. Moreover, new technologies to assist extraction high-pressure, microwaves, ultrasound, etc. However, the notion of expertise in plant extraction remains to this day a balanced combination of the mastery of technical parameters, and tradition.

Overspecies of plants have been documented throughout the world to date, and botanists are still discovering around more every year. The majority of the plants used by humans are dedicated to medicine, phytotherapy in particular. A passing fad for some, medicine for others, this traditional practice is based on the use of the natural therapeutic properties of plants in treating pathologies.

Although it is the oldest care technique in existence, it has been supported by various types of research clinical and pharmacological. In particular, its success arises from a deeper understanding of plants and from a qualitative selection of varieties.

In order to respond to changing consumer demands, new and more modern medicinal formats are being introduced gel capsules, tablets, hard capsules, etc. Because of the advancements made in extraction methods, new medicinal properties have been discovered, and the set of active molecules in the plant are being better and better preserved.

In the spirit of modern phytotherapy, Berkem manufactures traditional plant extracts that endeavour to respect the plant as a whole. It is thus defined as an operation of the separation of one or several constituents solid or liquid contained in a solid object by solubilisation in a fluid. This fluid, generally known as a solvent, may be a liquid or a gas water vapour or supercritical fluids. In thermodynamics, the solid object is a homogeneous mixture in equilibrium, i.

This can be compared with the treatment of heterogeneous mixtures, which can be fractionated by filtration, decantation or centrifugation, for example. Following this disturbance, the solid is no longer in equilibrium and the solid-solvent system will advance towards a new equilibrium through mass transfer. The whole art of extraction is a question of understanding the parameters that influence nature, and the kinetics of this mass transfer from the solid to the liquid.Introduction: Paris polyphylla Smith is a high value medicinal plant available in Sikkim Himalaya which is well known in local traditional medicine system.

Americas due to its robust healthcare industry accounts to the major share of global plant extracts market.Humans are dependent on plants for basic needs such as food, clothing, and shelter for centuries [ 1 ]. Plants have also been used as arrow and dart poisons for hunting, poisons for murder, hallucinogens used for ritualistic purposes, stimulants for endurance, and hunger suppression, as well as inebriants and medicines [ 1 ].

Medicinal plants have been a source of wide variety of biologically active compounds for many centuries and used extensively as crude material or as pure compounds for treating various disease conditions. Plant-based traditional medicine plays a key role in the development and advancement of modern studies by serving as a starting point for the development of novelties in drug discovery [ 3 ].

Various modern drugs were extracted from traditional medicinal plants through the use of plant material following the ethno botanical leads from indigenous cures used by traditional medical systems [ 4 ]. In developing countries and rural societies, the use of medicinal plants is both a valuable resource and necessity, and furthermore, it provides a real alternative for primary healthcare systems [ 5 ].

The use of plants as medicines predates written human history. Knowledge of plant use was widespread in ancient civilizations. Until the middle of the nineteenth century, plants were the main therapeutic agents used by humans, and even today, their role in medicine is still relevant. For example, traditional medicine TM practices have been used for thousands of years by people in Africa, China, India and many other countries [ 8 ].

Even in developed countries, plant-based traditional medicines are often termed complementary or alternative medicine CAMand their use has increased steadily. The plant chemicals used for arrow or dart poisoning purposes are largely the secondary metabolites, which are derived biosynthetically from plant primary metabolites e.

Secondary metabolites can be classified parasole socks review several groups according to their chemical classes, such as alkaloids, terpenoids, tannins, phenolics, and others [ 10 ].

Most of these secondary metabolites are used for plants defense against predators. Medicinal plants are now more focused than ever because they have the capability of producing many benefits to society especially for medicinal uses. The medicinal power of these plants is due to their phytochemicals which can cause definite physiological actions on the human body. Phytochemicals are natural compounds which occur in plants such as medicinal plants, vegetables, and fruits that work with nutrients and fibers to act against diseases or more specifically to protect against diseases [ 1112 ].

Medicinal plants because of their accessibility and affordable health care are an important source of livelihoods for indigenous and rural populations. They are also the source of many active ingredients for modern pharmaceuticals. Between 50, and 80, flowering plants are used for medicine worldwide, many of them are collected from wild resources [ 12 ].

Herb as a group of plants was also used as food vegetables and flavors for hundreds of years in many parts of the world. Herbs have been traditionally regarded as natural remedies for common ailments of a human. Nearly all cultures and civilizations from ancient times to the present day have used herbal medicines which are antimicrobial sources to cure infections [ 13 ]. Conventional antifungal and antibacterial treatment of infections becomes inefficient to cure patients, providing resistance of microorganisms.

Table 1 shows compounds or extracts are drugs or on the process of clinical trial stage derived from plants and their therapeutic use.Research Article. How to cite this article: Alemu Mekonnen Tura. DOI: Herbs and spices have been used during the middle ages for flavoring, food preservation and medicinal purposes. The aim of this study was to evaluate and compare the phytochemicals and antimicrobial properties of extracts of nine types of commercial herbs and spices commonly used in the production of ready meals.

Phytochemical screening tests was conducted for nine spice species and found that extract contains a variety of Phytochemicals like saponins, tannins, flavonoids, terpenoids, glycosides and reducing sugars and among which there is higher level of precipitation for phenol and flavonoids. As they are essential source of antimicrobial agents against pathogens, their extracts were tested for its antimicrobial activity by well diffusion method using Nutrient agar against human pathogenic bacteria like Staphylococcus aureus.

The findings showed potential antibacterial properties of the extracts against the organisms tested. Among the nine-spice extract tested, ethanol extract of garlic shows higher inhibition zone. Finding of the study concluded that Spices possesses the anti-microbial capabilities against infections diseases caused by Staphylococcus aureus and seems to be useful in the discovery of antibiotic drugs.

Keywords: Herbs, spices, Phytochemical tests, Antimicrobial activity, Disc diffusion method. The medicinal power of these plants lies in phytochemical constituents that cause definite pharmacological actions on the human body. The search for new pharmacologically active agents obtained by screening natural resources such as plant extracts has led to the discovery of many clinically useful drugs for the treatment of human diseases.

The most important of these bioactive constituents of plants are alkaloids, tannin, flavonoid and phenolic compounds [3,4]. Among these plants, Spices which include leaves coriander, mintbuds clovebulbs garlic, onionfruits red chili, black pepperstem cinnamonrhizomes ginger and other plant parts, have been defined as plant substances from in digenous or exotic origin, aromatic or with strong taste, used to enhance the taste of foods.

Spices and herbs have played a dramatic role in civilization and in the history of nations. The delightful flavour and pungency of spices make them indispensable in the preparation of palatable dishes [6]. In addition, they are reputed to possess several medicinal and pharmacological properties in particular, antimicrobial activity against different types of microbes []. Apart from enhancing the taste and flavour of food, spices have been widely believed to exert digestive stimulant action [13].

Spices have been generally believed to intensify salivary flow and gastric juice secretion, thereby aiding digestion [14]. Several pharmacological preparations available to correct digestive disorders employ certain spices besides other plant substances [15]. A few medicinal properties of spices such as tonic, carminative, stomachic, diuretic, and antispasmodic have long been recognized []. These attributes, largely empirical, nevertheless efficacious, have earned them pharmacological applications in the indigenous systems of medicine as digestive stimulants and to relieve digestive disorders [13].

Plant extracts and natural compounds purified from plants have been used by humans for many centuries for the treatment and alleviation of a variety of inflammation related diseases, including cancer [19].

Extraction, Isolation And Characterization Of Bioactive Compounds From Plants’ Extracts

Spice derived phytochemicals have an enormous potential in the prevention and treatment of cancer []. They can induce apoptosis, suppress proliferation of tumor cells, inhibit invasion and angiogenesis, and prevent even bone loss.

These phytochemicals mediate their effects through multiple targets and yet pharmacologically they are highly safe [20]. Phytochemicals are natural bioactive compounds found in plants. Phytochemicals are divided into two groups; primary and secondary compounds. These classes are according to their functions in plant metabolism.

Amino acids, sugars, proteins and chlorophyll are known as primary compounds while secondary compounds consist of alkaloids, terpenoids, phenolic compounds and many more [23]. Plant produces these chemicals to protect itself, but recent research demonstrates that many phytochemicals can protect humans against diseases. There are many phytochemicals in fruits and herbs and each works differently.Protocol DOI: This chapter presents an overview of the preparation of extracts from plants using organic solvents, with emphasis on common problems encountered and methods for their reduction or elimination.

In addition to generally applicable extraction. In addition to generally applicable extraction protocols, methods are suggested for selectively extracting specific classes of plant-derived compounds, and phytochemical procedures are presented for the detection of classes of compounds encountered commonly during extraction, including selected groups of secondary metabolites and interfering compounds. Successful extraction begins with careful selection and preparation of plant samples and thorough review of the appropriate literature for suitable protocols for a particular class of compounds or plant species.

During the extraction of plant material, it is important to minimize interference from compounds that may co-extract with the target compounds, and to avoid contamination of the extract, as well as to prevent decomposition of important metabolites or artifact formation as a result of extraction conditions or solvent impurities.
