Introduction  to Pharmacognosy: 

 

Definition

                                      The piece of data stressed remedial drugs got from plants or other ordinary sources.(Definitions from Oxford Languages) 

Pharmacognosy is the examination of plants or other normal sources as a possible wellspring of prescriptions. The American Society of Pharmacognosy describes pharmacognosy as 

 Pharmacognosy is widely portrayed as the legitimate and exact examination of the fundamental, physical, substance, and unmistakable characteristics of harsh prescriptions of vegetable, animal, and mineral start close by their arrangement of encounters, method for improvement, collection and foundation for the market. 

 Plant science fuses the ID (logical order), genetic characteristics, and advancement of plants. Engineered depiction of consolidates the disengagement, recognizing verification and estimation of constituents in plant materials. Pharmacology is the examination of the common effects that the artificial materials in restorative plants have on cell social orders, animals and individuals practical perspectives as follows 

 Quality control (character, flawlessness, consistency) 

 Efficacy (accommodating signs, pharmacological assessments) 

 Safety (opposing reactions, drug participations, contraindications, security measures 

The Scope of Pharmacognosy: 

 It is one of the five essential spaces of pharmacy. 

 Pharmacognosy gives a sound data on the vegetable meds under plant science and animal medications under zoology. 

It in like manner joins plant logical arrangement, plant raising , plant pathology, plant innate characteristics and by this data one can improve the advancement systems for both restorative and fragrant plants. 

 Nowadays phytochemistry (plant science) has gone through the basic improvement. This fuses a variety of substances that are assembled by plants and consolidated by plants. A central obligation to the movement of normal science: 

This has done by the pattern setting advancements of improvement, purifying, conspicuous evidence (depiction) of medications from nature. 

 Concepts of natural science and substance planning help with the improvement of arrangement, getting ready and limit advances of medications. It similarly gives data on chemotaxonomy, biogenic pathways for the improvement of extraordinary trimmings. A basic association among pharmacology and restorative science. 

3. Newly distinguished plant drugs are changing over into prescription as purified phytochemicals. Pharmacognosy is major for the advancement of new prescriptions since unpleasant meds are used for the arranging of galanicals or as a wellsprings of therapeutically powerful metabolites. In short Pharmacognosy is a critical association among medications and fundamental science similarly as ayurvedic and allopathic plan of remedies. 

Pharmacognosy is an investigation of dynamic guidelines of crude prescriptions and which can be help in allocating, figuring, and gathering of estimations structures. ü In substitute way the all out data on Pharmacognosy will help in the new example that is in ventures, As an assessment gadgets and in new prescription transport structures, and all of the parts of medications and one can improve the clinical benefits workplaces across the world. 

4. Basic PRODUCTS AS MODELS FOR SYNTHESIS OF NEW DRUGS :

Eg: Morphine is the model of a colossal get-together of solid prescriptions . Cocaine for close by narcotics Atropine for explicit spasmolytics

5. Drugs OF DIRECT THERAPEUTIC USES:

 Among the standard constituents which even now can't be replaced are critical social event of serums poisons, steroids, ergot alkaloids, vincristine, etc 

6. BIOSYNTHETIC PATHWAYS INVESTIGATION:

 Biosynthetic pathways are of fundamental and assistant metabolites. A part of the huge pathways are Clavin 's example of photosynthesis, Shikimic destructive pathway of fragrant blends Acetate hypothesis for antharacene glycosides, Isoprenoid hypothesis for terpens 

7. Improvement AND COLLECTION OF MEDICINAL PLANTS :clove, cinchona , cinnamon, senna, opium, etc• 

8. Arranging OF HERBAL FORMULATIONS : churnas, asvas, aristas, leha, etc• 

9. Improvement OF TISSUE CULTURED PLANTS 

Starting 

 Crude Drugs: - Crude meds are the prescriptions, which are gained from basic sources like plant, Animals, minerals, marine, microorganisms and they are used as, for instance, they occur in nature with no planning except for, drying and size decline. Crude meds is implied the basic thing that has not been in forefront in regard or improved in condition by any cycle or treatment past that which is key for its proper packaging and expectation from disintegrating. 

 Recently it joins: 

 1-Modern isolation methodologies. 

 2-Pharmacological testing procedures to design refined substances. 

 3-Cultivation and expansion by tissue culture 

SOURCES OF DRUG: 

 Drugs used in medicine may be characteristic and inorganic in nature. Characteristic drugs are fundamentally of 2 sorts . 

 1. Totally designed : The consequence of man 's arrangement of new substance components ( structures) non – existent before the hour of made science. 

 2. Drugs of characteristic start : Produced in the living cell, biogenic prescriptions (crude meds) 

 Pharmacognosy is the subject of harsh drugs procured from the plants (vegetable), animal and mineral start. Or then again It can moreover portrayed as the objective examination of unpleasant meds of the typical sources took care of tentatively.
