Chemical Classification of Crude Drugs
Carbohydrates
Carbohydrates are compounds containing the elements
carbon, hydrogen, and oxygen. They are either aldehyde or
ketonic alcohols in which hydrogen and oxygen are present
in the same ratio as in water.
Glycosides
Glycosides are non reducing substances that, on hydrolysis
brought about by reagents or enzymes, yield one or more
reducing sugars among the products of hydrolysis. The nonsugar part of the molecule is called the aglycone or genin;
the sugar component is called the glycone.
Tannins
Tannins are complex organic, non-nitrogenous derivatives of
polyhydroxy benzoic acids.
Volatile Oils
Volatile oils are odorous principles found in various parts of
the plant. They are called volatile oils because they are volatile
in steam and at higher temperatures evaporate.
Lipids
The term lipid refers to fixed oils, fats, and waxes. They are
esters of long-chain fatty acids and alcohols and closely
related derivatives. They are stored in seeds, spores, and
vegetative perennial organs such as bulbs
Resins and Resin Combinations
The term resins are brittle secretions or exudations of plant
tissues, either produced normally or as the result of pathogenic
conditions. Resins, as a class, are hard, transparent or
translucent brittle substances. They are generally heavier
than water (sp. gr. 0.9–1.25).
Examples
Acacia arabica, Astragalus gummifer, Cyamopsis
tetragonolobus and Plantago ovata
Examples
Anthraquinone Glycosides: Cassia acutifolia, Aloe perryi,
Rheum emodi.
Saponins Glycosides: Glycyrrhiza glabra, Terminalia arjuna
Cyanophore Glycosides: Prunus serotina
Isothiocyanate Glycosides: Brassica alba
Cardiac Glycosides: Strophanthus Kombe, Digitalis
purpurea
Bitter Glycosides: Picraena excelsa, Swertia chirata
Examples
Emblica officinalis, Terminalia arjuna, Uncaria gambier ,
Acacia catechu and Terminilia chebula
Examples
Foeniculum vulgare, Peucedanum graveolens, Carum Carvi
Examples
Fixed oils: Ricinus communis, Oleum Olivae, Prunus
amygdalus and Hypoprion brevirostris
Fats: Theobroma cacao
Waxes: Apis mellifera, Prunus amygdalus
Examples
Podophyllum hexandrum, Cannabis sativa, Ipomoea purga,
Capsicum annuum, Curcuma longa, Ferula foetida, and
Zingiber officinalis.

Alkaloids
The term alkaloid can be defined as a plant base. Alkaloids
mean “alkali-like,” referring to the basic nature of these
plant constituents. They are essentially basic nitrogenous
compounds of vegetable origin, possessing some marked
physiological action
3. Factors Influencing Quality of Crude Drugs
Examples
Pyridine and Piperidine: Lobelia inflata, Nicotiana tabacum
Tropane: Theobroma cacao, Atropa belladonna , Datura
metel and Hyoscymus niger
Quinoline: Cinchona calisaya
Isoquinoline: Papaver somniferum, Cephaelis ipecacuanha
Indole: Claviceps purpurea, Rauwolfia serpentina
Purine: Tea, coffee
Protein: Gelatin, Ficin, Papain
Vitamins: Yeast
Triterpenes: Rasna, Colocynth
Environmental Conditions:
Plant growth and development are controlled environmental
conditions.
The long-term climatic conditions for a region determine
the type of vegetation in that region, and regional
environmental factors affect growth and development of
the plants.
The ecologically important environmental factors affecting
plant growth are light, temperature, humidity, rainfall and
altitude.
Effect of Altitude on Cultivation of Plants

Type of Soil with Its Characteristics
Type of soil Characteristics
Sandy Soil Sandy soil (0.05 to 2 mm) is good for plants. It is granular and consists of rock and mineral particles. The
texture is gritty and sandy soil is formed by the disintegration and weathering of rocks such as limestone,
granite, quartz and shale. Sandy soil retains moisture and nutrients.
Silty Soil Silty soil (0.002 to 0.05 mm) is considered to be one of the most fertile of soils. It is composed of minerals
like Quartz and fine organic particles. It is granular like sandy soil but it has more nutrients than sandy
soil and it also offers better drainage.
Clay Soil Clay soil (less than 0.002 mm) is formed after years of rock disintegration and weathering. It is also formed
as sedimentary deposits after the rock is weathered, eroded and transported.
Loamy Soil This soil is the ideal for cultivation, consists of sand, silt and clay to some extent. It is considered to be the
perfect soil. The texture is gritty and retains water very easily, yet the drainage is well.
Peaty Soil It is basically formed by the accumulation of dead and decayed organic matter and naturally contains much
more organic matter than most of the soils. It is generally found in marshy areas. Peaty soil is blocked by
the acidity of the soil.
Chalky Soil Chalky soil is very alkaline in nature and consists of a large number of stones. Chalky Soil, apart from being
dry also blocks the nutritional elements for the plants like Iron and Magnesium. The fertility of this kind of
soil depends on the depth of the soil that is on the bed of chalk. This kind of soil is prone to dryness and
in summers it is a poor choice for plantation.
