Comparative study – American Herbal Pharmacopoeia MCQs With Answer
Introduction: The American Herbal Pharmacopoeia (AHP) is a specialized compendium focused on high-quality monographs for medicinal herbs. This blog provides M.Pharm students with a compact, comparative MCQ set to deepen understanding of AHP’s structure, analytical requirements, and how it aligns or differs from other standards such as USP, BP and WHO guidelines. Emphasis is placed on monograph components, identity and purity tests, standardization strategies, safety evaluation, and quality assurance practices including GACP and GMP. Each question probes practical and regulatory aspects important for pharmacists engaged in herbal drug analysis and formulation development.

- It only tests for microbial contamination
- It prescribes identical numerical limits for all herbs without risk assessment
Correct Answer: It provides guidance on relevant contaminants, recommended limits or references to regulatory limits, and suitable analytical methods
Q8. Which best describes the AHP’s stance on Good Agricultural and Collection Practices (GACP)?
- GACP is considered irrelevant for pharmaceutical quality
- AHP emphasizes GACP as foundational for ensuring consistent quality and minimizing contamination or adulteration
- GACP only applies to synthetic drugs
- AHP requires no cultivation guidance and focuses only on laboratory tests
Correct Answer: AHP emphasizes GACP as foundational for ensuring consistent quality and minimizing contamination or adulteration
Q9. When comparing AHP monographs to USP herbal monographs, which of the following is generally true?
- AHP monographs are always legally enforceable while USP monographs are not
- USP focuses more on finished dosage forms and compendial assays, while AHP often includes more extensive botanical, ethnobotanical and safety information
- USP excludes all chemical testing for herbs
- AHP never references pharmacopoeial methods
Correct Answer: USP focuses more on finished dosage forms and compendial assays, while AHP often includes more extensive botanical, ethnobotanical and safety information
Q10. In AHP monograph structure, which section provides recommended analytical procedures and acceptance criteria?
- Ethnobotany section
- Identification, Purity, and Assay/Analytical Methods sections
- History of cultivation
- Sales and distribution notes
Correct Answer: Identification, Purity, and Assay/Analytical Methods sections
Q11. For standardization of a polyherbal extract, how does AHP typically suggest establishing quality?
- Rely only on total extractive value without marker analysis
- Use a combination of marker compound assays, fingerprint profiling (TLC/HPTLC/HPLC), and identity tests to ensure batch-to-batch consistency
- Accept visual color as sole quality parameter
- Standardize only by moisture content
Correct Answer: Use a combination of marker compound assays, fingerprint profiling (TLC/HPTLC/HPLC), and identity tests to ensure batch-to-batch consistency
Q12. Which of the following is a distinctive feature of AHP regarding clinical information?
- AHP provides no citation of clinical research
- AHP monographs often summarize available clinical trials, pharmacology and human safety data to contextualize traditional use
- AHP prescribes specific off-label uses without evidence
- AHP only lists homeopathic dilutions
Correct Answer: AHP monographs often summarize available clinical trials, pharmacology and human safety data to contextualize traditional use
Q13. Which validation parameter is most critical when AHP recommends an HPLC assay for quantifying a marker compound?
- Regimen of patient administration
- Specificity, accuracy, precision, linearity and robustness of the method
- Brand popularity of HPLC instruments
- Storage temperature of marketed products only
Correct Answer: Specificity, accuracy, precision, linearity and robustness of the method
Q14. How does AHP address adulteration issues in herbal materials?
- It ignores adulteration as a non-issue
- It provides information on common adulterants, characteristic markers of adulteration, and recommended detection methods
- It assumes all commercial herbs are pure
- It endorses any economically motivated substitutions
Correct Answer: It provides information on common adulterants, characteristic markers of adulteration, and recommended detection methods
Q15. In comparing stability recommendations, what approach does AHP take for herbal extracts and finished products?
