Abstract:Objective To study the fingerprints differences of root, main stem, lateral branch, leaf, and flower of Verbena officinalis L. Methods Eleven batches of Verbena officinalis L. from different producing areas were collected. The fingerprints of medicinal material, root, main stem, lateral branch, leaf, and flower of Verbena officinalis L. were determined by ultra high performance liquid chromatography. Similarity evaluation, cluster analysis, principal component analysis, and partial least square discriminant analysis were used to analyze the chemical pattern recognition of fingerprints of different parts. Results The ultra high performance liquid chromatography fingerprints of medicinal material, root, main stem, lateral branch, leaf, and flower of Verbena officinalis L. were established, and 22, 14, 20, 20, 21, 22 common characteristic peaks were confirmed, respectively, and three components (5-hydroxyl verbenalin, verbenalin, and verbascoside) were identified. The higher similarity between medicinal material and its lateral branch, but lower similarity for root. Heat maps showed that the contents of chemical constituents in different parts were different, which mainly enriched in flower. Clustering analysis showed that the consistency between herbs and lateral branches was high. Combined with principal component analysis and partial least square discriminant analysis, 5-hydroxyl verbenalin was an important indexes of the formation of different parts of the difference. Conclusion The quality of Verbena officinalis L. can be improved by harvesting at flowering stage and removing root for medicinal application, which provided experimental reference for removing root for medicinal application.
