Lignans are low-molecular-weight secondary metabolites in vascular plants and thought to protect the plants from pathogens by their antibacterial and antioxidant properties. They have also been proposed as cytokinins and as intermediates in lignification, suggesting their critical roles in plant growth and development. In addition, lignans have been remarked because it is reported that they have various physiological effects for human. Until now, HPLC-DAD has been mainly used for lignan analysis. However, it is very difficult to establish the comprehensive analytical system for lignans because they exist in a very small amount and various analogs and metabolic intermediates also are in plants. In this study, we have successfully established a high-sensitive microanalytical method for lignans and phenylpropanoids using capillary LC-ESI-MS^n. Moreover, we investigated correlation between light conditions which is a critical factor for plant growth and lignans content in leaves of lignans rich plants, Forsythia spp.
