Abstract:

Metabolomics analysis of Acanthopanax senticosus(Rupr. et Maxim.)Harms and Acanthopanax sessiliflorus(Rupr. et Maxim.)Seem leaves was performed using GC-MS technology. With analysis of PCA and OPLS-DA, the leaves of A. senticosus and A. sessiliflorus were divided into three developmental periods: growth period, exuberant period, and autumn period. A total of 53 differential compounds such as sugars, amino acids, organic acids, fatty acids and polyols were filtered from the leaves of A. senticosus at three periods. A total of 51 differential compounds such as sugars, amino acids, organic acids, fatty acids and polyols were filtered from the leaves of A. sessiliflorus at three periods. Further analysis showed that the leaves of A. senticosus and A. sessiliflorus had the most differential compounds in the exuberant period and autumn period. Among these differential compounds, the leaves of A. senticosus mainly included sugars and organic acids. The leaves of A. sessiliflorus also included fatty acids and polyamine compounds except for sugars and organic acids. The results initially reveal the accumulation patterns of primary metabolites in the two medicinal plants from the same genus at different periods, and provid a theoretical basis for the leaf utilization of the two plants.

Key words: Acanthopanax senticosus, Acanthopanax sessiliflorus, metabolomics, multivariate statistical analysis
