Methods Eighteen batches of commercial medicinal materials of Lignum Dalbergiae Odoriferae were identified and analyzed by macroscopical identification, thin layer chromatography (TLC), and volatile oil assay according to the Chinese Pharmacopoeia published in 2010. Visible spectrometry was used to determine the content of total flavonoids from the qualified samples. And the gas chromatography was applied to evaluate the content of nerolidol from volatile oils of the qualified samples. Results Only 33.3%of the samples met the standard of Chinese Pharmacopoeia. The total flavonoid content of the qualified samples was in the range of 21.6-29.0 mg/g. The content of nerolidol from volatile oils of the qualified samples was in the range of 294-574 mg/g.
