Which are examples of official spirits?

• A. Aromatic ammonia, camphor, compound orange, peppermint
• B. Gum arabic, senna, peppermint
• C. Ethanol, methanol, acetone
• D. Water, saline solution

Answer: (A)

Spirits in pharmacopeia are clear, volatile, aromatic liquids that are officially standardized and listed for use. They are typically prepared by dissolving volatile compounds or essential oils in alcohol (or water) to create defined aromatic liquids used as solvents, flavors, or mild topical agents.

The items in the correct choice are all examples of official spirits: aromatic ammonia spirit, camphor spirit, compound orange spirit, and peppermint spirit. Each is a named, defined volatile liquid with a characteristic odor, recognized in the pharmacopoeia as an official spirit, and prepared in a standardized way for consistent use.

The other groups don’t fit the category: gum arabic and senna are a mucilage and a laxative herb, not volatile aromatics; peppermint without the “spirit” designation refers to the plant or essential oil rather than a prepared aromatic liquid; ethanol, methanol, and acetone are solvents, not official aromatic spirits; water and saline solution are aqueous preparations, not volatile aromatic liquids.
