Study Notes

Storage of Crude Drugs

The most common method for preserving plant material is drying.
All drugs should be preserved in well-closed and filled containers, stored in water-proof, fire-proof, and rodent-proof premises.

Examples of Poor Storage Conditions

Opium: Loss of morphine occurs when stored in the open.
Digitalis: Should be stored with a dehydrating agent to prevent enzymic reactions.
Squill: Should be stored in a tightly closed container to prevent moisture absorption.
Biological preparations: Need to be stored at low temperatures to preserve their activities.

Storage Premises

Storage facilities should be well-aerated, dry, and protected from light, with air-conditioning and humidity control equipment.
The floor should be tidy, without cracks, and easy to clean.
Shelves should keep the material a sufficient distance from the walls, with measures to prevent pest infestation.

Storage Conditions

Plastic sacks effectively seal the contents, but long-term storage is not recommended.
Ideal conditions are always in a cool and dry place, away from light.
Temperature, water, and light are the main factors that affect drugs.

Special Storage Requirements

Digitalis and Indian hemp should not be allowed to become air-dry, or they lose a considerable part of their activity.
Volatile oils and fixed oils should be stored in sealed, well-filled containers in a cool, dark place.
Air-dry drugs are liable to attack by insects and other pests, and should be examined frequently during storage.

Deterioration of Crude Drugs

Moisture can cause rapid changes of active principles due to enzymes requiring a sufficient moisture to activate them.
Light can affect drugs, especially those containing marked colors.
Hygroscopic materials can become deteriorated by absorbing moisture in a humid atmosphere.

Packaging and Storage

Processed medicinal plant materials should be packaged in clean, dry boxes, sacks, bags, or other containers in accordance with standard operating procedures.
Materials used for packaging should be non-polluting, clean, dry, and in undamaged condition.
Fresh medicinal plant materials should be stored at appropriate low temperatures, ideally at 2-8°C; frozen products should be stored at less than -20°C.
Small quantities of crude drugs can be stored in air-tight, moisture-proof, and light-proof containers.
Wooden boxes, sacks, bales, and paper bags should not be used for storage of crude drugs.
