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.

Q1. What is the primary purpose of an American Herbal Pharmacopoeia (AHP) monograph?

• To provide legally binding regulations for herbal product marketing
• To offer a comprehensive, science-based reference detailing identity, purity, and recommended assays for a specific herb

Correct Answer: TLC/HPTLC combined with reference standards and densitometry when applicable

Q5. In the context of AHP, what is the role of DNA authentication techniques in monographs?

• They are the only acceptable identity test and replace all chemical tests
• They are recommended as complementary tools to confirm species identity, especially for processed materials
• They are discouraged due to inaccuracy
• They are unrelated to botanical identification and used solely for microbial detection

Correct Answer: They are recommended as complementary tools to confirm species identity, especially for processed materials

Q6. Which safety-related content is routinely included in AHP monographs that is particularly useful for M.Pharm students?

• Market share and brand competitors
• Known adverse effects, toxicology data, contraindications and recommended dose ranges
• Instructions for agricultural irrigation
• Exclusive information on intravenous formulations only

Correct Answer: Known adverse effects, toxicology data, contraindications and recommended dose ranges

Q7. How does AHP handle contaminants such as pesticides, heavy metals and mycotoxins relative to other compendia?

• It omits testing for contaminants entirely
• It provides guidance on relevant contaminants, recommended limits or references to regulatory limits, and suitable analytical methods
• 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?

• They are used exclusively for legal enforcement
• They replace laboratory controls completely

Correct Answer: Reference materials serve as authenticated standards for identity tests and assay calibration

Q18. How does AHP handle ethnobotanical and traditional use information within monographs?

• It ignores traditional usage and focuses only on synthetic derivatives
