[Objectives] This paper aimed to study the quality standard of pummelo pericarp from Guangxi. [Methods] The medicinal material was identified by microscopy and thin-layer chromatography, and the contents of moisture, total ash, acid-insoluble ash and extract in the medicinal material were determined according to the methods of the Chinese Pharmacopoeia(2010 edition). [Results] The content limits for moisture, total ash, acid-insoluble ash and extract were determined (moisture ≤ 12%; total ash ≤ 6.0%; acid-insoluble ash ≤ 0.6%; water-soluble extract ≥ 43.0%; naringin ≥ 10.00 mg/g). The micro-characteristics of pummelo pericarp were identified, and a thin-layer chromatography identification and content determination method was established. [Conclusions] The established method can provide an experimental basis for the formulation of quality standard for pummelo pericarp. [ABSTRACT FROM AUTHOR]
