PHARMACOGNOSY AND PLANT CHEMISTRY
1. A glucosan yield units on hydrolysis. While inulin is a ______
A. Fructosan
B. Hexosan
C. Pentosan
D. Diosan
E. All of these
Inulin is a D-fructofuranose polymer whose residues are linked by β-2,1 bonds
2. The usual source of tannins from plants is from the:
A. Barks/Stems
B. Seeds
C. Roots
D. Rhizomes
E. All of these
Tannins are usually localized in specific plant parts such as leaves, fruits, barks and
stems.
3. Ethanol and citric acid are produced by the cellular respiration of carbohydrates,
especially
A. Glucose
B. Sucrose
C. Fructose
D. Cathartic
E. Lactose
Glucoes is the major fuel in glycolysis, Kreb’s cycle and other important
biochemical pathways.
4. Because mannitol is absorobed from the GIT and parenterally is not metabolized, then it is
used as:
A. Digestant
B. Osmotic Diuretic
C. Acidulant
D. Cathartic
E. Laxative
Aside from these properties, mannitol is also eliminated readily by gromerular
filtration. These have led to the use of mannitol as a diagnostic aid and as an osmotic
diuretic.
5. This gum has pseudo-plastic property to enable ointments to hold their shape and spread
readily.
A. Karaya
B. Xanthan
C. Guar
D. Locust Bean
E. Indian Gum
, 6. The following are general steps in the preparation of the crude drug for commercial
market, except:
A. Harvesting
B. Garbling
C. Storage and Drying
D. None of the above
The general steps in the preparation of crude drugs include: collection, harvesting,
drying, garbling, packaging, storage and preservation.
7. The usual source of fixed oils:
A. Flower
B. Seeds
C. Leaves
D. Stems
E. Roots/Rhizomes
8. This is used as an antidote for alkaloidal poisoning:
A. Lactic Acid
B. Tannic Acid
C. Tartaric Acid
D. Picric Acid
E. Gallic Acid
Tannic Acid is an astringent and an alkaloidal precipitant
9. The most important of the opium alkaloids is:
A. Heroin
B. Codeine
C. Morphine
D. Narcotine
E. Papaverine
10. The red-colored product formed when tannins are treated with hydrolytic agents is
known as:
A. Amolonin
B. Diosgenin
C. Phlobaphenes
D. Catechin
E. Leucocyanidin
When non-hydrolyzable or condensed
11. The most widely used alkaloid is:
A. Heroin
B. Codeine
C. Morphine
D. Narcotine
E. Papaverine
