Study Notes
UNORGANIZED DRUGS
- Define as crude drugs from plant or animal sources, lacking cellular structure; may be mixtures or decomposition products.
- Classified into Gums, Lattices, Juices, Resins, and resin combinations.
GUM ARABIC
- Sourced from Acacia senegal and other Acacia species, primarily from Sudan and West Africa.
- Complex composition includes arabin, calcium salts of Arabic acid, polysaccharides, proteins, and approximately 47% water.
- Functions as a general stabilizer in emulsions and lozenges; used in cough and diarrhea preparations.
- Test methods:
- Nearly fully soluble in equal weight of water.
- Precipitation reaction with lead subacetate; no precipitate with lead acetate.
- Blue color with benzidine and hydrogen peroxide indicates peroxidase presence.
GUM TRAGACANTH
- Obtained from Astragalus microcephalus and related species across Western Asia.
- Composed of two fractions: tragacanthin (water-soluble) and bassorin (water-insoluble).
- Used in pharmaceuticals as a suspending agent and binder in tablets.
- Test observations:
- Swells in water to a gelatinous mass.
- Color change with iodine solutions indicating component breakdown.
STERCULIA GUMS
- Extracted from Sterculia urens, mostly produced in India and Pakistan.
- Partial hydrolysis yields D-galactose, L-rhamnose, and D-galacturonic acid.
- Granular form serves as a bulk laxative; powdered form used in pastes and denture fixatives.
- Low solubility in water but swells significantly; color change upon boiling with potash.
AGAR (JAPANESE ISSINGLASS)
- Derived from species of red algae, especially Gelidium.
- Major components include agarose (neutral polymer) and agaropectin (sulphonated polysaccharide).
- Identifies through solubility tests: insoluble in cold water but swells and dissolves in boiling water.
- Functions as a laxative, suspending agent, and disintegrant for tablets; also used in bacteriological media.
OLIBANUM (FRANKINCENSE)
- Oleogum resin obtained from Boswellia species, native to northeastern Africa and Arabia.
- Contains 3-8% volatile oil, 60-70% resin, and polysaccharides of galactose and arabinose.
- Historically used in incense and believed to have anti-inflammatory and anticancer properties, as well as cognitive enhancement in animals.
GELATIN
- Obtained by treating animal tissues, mainly skin and bones, with hot water to convert collagen into soluble gelatin.
- Primarily composed of glutin protein, indicating positive tests for proteins.
- Commonly used in capsule preparation, food products, and bacteriological culture media.
