1.Carbohydrates - ans¢Gums - Acacia, Tragacanth, Guargum
¢Mucilages - Plantago seed
¢Others - Starch, Honey, Agar, Pectin, Cotton
Advantage of pharmacological classification - ans¢This system of classification can
be used for suggesting substitutes of drugs if they are not available at a particular
place or point of time.
Advantages of alphabetical classification - ansIt is easy and quick to use
There is no repetition of entries and is devoid of confusion.
In this system location, tracing and addition of drug entries is easy
Advantages of chemical classification - ans¢This system of classification is a
popular approach for phytochemical studies.
advantages of morphological system of classification - ans¢This is more convenient
for practical study especially when the chemical nature of the drug is not clearly
understood.
¢
¢Morphological classification is more helpful to identify and detect adulteration.
Advantages of taxonomic classsification - ansAllows for precise and ordered
arrangement of drugs.
It is helpful for studying evolutionary developments
Accommodates any drug without ambiguity
alkaloids - ans¢Nitrogenous substances of plant origin
¢Pyridine and Piperidine - Lobelia, Nicotiana
¢Tropane - Coca, Belladonna, Datura, Stramonium, Hyoscyamus, Henbane
¢Quinoline - Cinchona
Alphabetical classification - ansAlphabetical classification is the simplest way of
classification
¢Crude drugs are arranged in alphabetical order of their:
Botanical names
Common names
Local/ vernacular names
Arthritis - ansinflammation of a joint
, Crude Druge family, synonym, family pharmacognosy
Ascites - ansaccumulation of fluid in the peritoneal cavity
Asphyxia - ansInability to breath
Atrophy - ansto waste away a tissue or an organ
Carcinogenic - anscausing cancer
Carcinoma - anscancerous tumor
Cardiac depressant - ansSlows down the action of the heart
Cardiotonic - ansdrug that increases the strength of the heart contractions
Carminative Drug - anscausing the release of stomach or intestinal gas
Cathartic - ansHaving the power of cleaning the bowels-purgative
Chemical Classification - ansThe crude drugs are divided into different groups
according to the chemical nature of their relevant constituent.
The chemical classification of drugs is dependent upon the grouping of drugs with
identical constituents.
Classification of crude drugs may include - ansAlphabetical classification
Morphological classification
Pharmacological classification
Chemical classification
Taxonomic classification
Differences between organized and unorganized drugs - ansOrganized Drugs
These may be of plant or animal origin.
Unorganized Drugs
These may be of plant, animal or mineral origin.
These are direct part of plants or animals.
Unorganized Drugs
These are the product of plant or animals.
These have well defined cellular structure.
Unorganized Drugs
These do not have well defined cellular structure.
