Abstract:
Objective: To analyze the dynamic changes of phenolic acids and anthraquinones from the aerial parts of Xanthium sibiricum (Xanthii Herba) in different collection periods. Methods: To establish an HPLC method for simultaneous determination of chlorogenic acid, neochlorogenic acid, protocatechualdehyde, protocatechuic acid, cryptochlorogenic acid, caffeic acid, 1,3-dicaffeoylquinic acid, ferulic acid, 3,4- dicaffeoylquinic acid, 3,5-dicaffeoylquinic acid, 4,5-dicaffeoylquinic acid, aloeemodin, emodin, and chrysophanol in the aerial parts of X. sibiricum. Results: The contents of phenolic acids and anthraquinones in different harvest time showed dynamic changes. In mid July, the content of total phenolic acids was higher. The higher content of total anthraquinones was in late July. The contents of five total phenolic acids were higher in mid July, such as chlorogenic acid, protocatechuic aldehyde, ferulic acid, 3,5-dicaffeoylquinic acid, and 1,3-dicaffeoylquinic acid. The content of chlorogenic acid was higher in late June, and the rest of five phenolic acids were higher in mid July. Conclusion: This can provide the basis for determining the suitable harvest time of X. sibiricum.
