Abstract:Lonicera hypoglauca and Lonicera japonica belong to Lonicera, their morphological characteristics and pharmacological effects are similar. In order to investigate the functional components of the Lonicera hypoglauca grown in Xiaoguan Suiyang, Guizhou province and the distribution patterns of functional components in different flowering stages and different parts of the plant, representative samples were collected from the same origin but different parts of Lonicera hypoglauca and at different flowering stages in this study. Ultra Performance Liquid Chromatography-Quadrupole-Time of Flight Mass Spectrometry was used to analyse the composition of these samples from Lonicera hypoglauca. Forty compounds were identified. Comparisons were made on the composition of functional components and changes in their amounts for the samples collected from the flowers, leaves and branches of Lonicera hypoglauca between budding stage and full blooming stage. These studies not only demonstrated the main functional components of Lonicera hypoglauca and associate technical methods and approaches for examining and utilizing these active components, but also revealed the accumulation and distribution patterns of main medicinal components throughout a growth cycle of the plant. It was found that the different functional components of Lonicera hypoglauca have their own suitable timing and location for collection, and the flowers and leaves of the plant, irrespective of budding or full blooming stage, could be used for the development of pharmaceutical products and functional foods. This research also provides theoretical foundations in standardizing the cultivation, harvesting and deep processing of Lonicera hypoglauca.
