Review and Comparison of Acceptance Criteria for Senna and Its Preparations According to BP (2015 and 2020) and USP-NF (39-34 and 43-38)

Quality and quantity assurance of herbs are global concerns. This study aimed to classify and compare the monographs and test procedures of Senna parts and preparations according to two editions of BP and USP-NF. The monographs and specifications were compared to suggest a practical approach to extract relevant data.

BP 2015 and 2020, USP-NF 39-34 and 43-38, and scientific databases were used for literature review.

In both editions of USP-NF, determination of heavy metals was solely included for the powder and tablet of sennosides. In both editions of BP, assessment of microbial contamination was merely included in the monograph of dry extract of Senna, not for the rest of the monographs. Comparing two editions of BP indicated that in BP 2020, LC and HPTLC methods were added to assure the quality of pods and leaflets of Senna species.

Preparation of tabular data will assist analysts in extracting desired information and guidelines to prepare licensed herbal products. This approach could be applicable to select relevant tests according to the facilities and equipment of laboratories.
