Objective To examine the authenticity and quality of Chen Xiang’s products and decoction pieces. Methods Methods for characterizing, identifying and alcohol-soluble extracts were compared. The results were from 17 batches of agarwood samples from the medicinal herbs market and medical use units. Most of the appearance traits were inconsistent with the regulations. The 3 batches of samples identified were in conformity with the regulations, and 14 batches of samples were not in compliance; 16 batches of alcohol-soluble extracts were in line with “China.” Pharmacopoeia stipulates that 1 batch does not meet the requirements. Conclusion The specificity of the identification items of the “Chinese Pharmacopoeia” needs to be improved; more defective products and misuse of counterfeit goods are sold and used in the market and clinical practice.
