Chemical Recognition and Spectrum-Effect Relationship of UPLC-MS Chromatograms With Anti-Complementary and Antioxidant Activities of Myricariae Ramulus.
Introduction: Myricariae Ramulus (MR) is a traditional anti-inflammatory Tibetan medicine derived from the branches and leafy twigs of various Myricaria plants, such as Myricaria wardii Marquand.
Objective: This study performed spectrum-effect analyses on 15 batches of MR, sourced from various origins and medicinal parts, to identify quality markers associated with its anti-inflammatory effects.
Materials and methods: The anti-inflammatory effects of different extracts and fractions from M. wardii were evaluated in lipopolysaccharide-infected mice. Further analysis was conducted utilizing UPLC-Q-TOF-MS/MS in the negative ion mode to recognize the compound composition of ethyl acetate (EA) fractions from the branches and leafy twigs of M. wardii. Subsequently, anti-complementary and antioxidant activities were conducted via the hemolysis and ABTS radical scavenging methods, and UPLC chromatograms for 15 batches of samples were established. Finally, spectrum-effect analysis was performed by gray relational analysis and partial least squares regression to identify the quality markers.
Results: The EA fraction effectively alleviated inflammatory responses by regulating IL-6 and myeloperoxidase. A total of 46 compounds from M. wardii were recognized, which mainly encompass gallic derivatives, phenolic amides, flavonoids, and terpenoids. Activity assays demonstrated that the two activities of leafy twigs were significantly stronger than those of branches. Moreover, an obvious distinction in chemical composition between the two parts was observed. Combining the spectrum-effect analysis results, methyl 3,4-dihydroxy-5-methoxybenzoate, myricarin A, protocatechualdehyde, and N-feruloyl normetanephrine from the branches, and protocatechuic acid from the leafy twigs were considered quality markers.
Conclusion: These results provide insights into improving the quality control of MR.
期刊介绍：
Phytochemical Analysis is devoted to the publication of original articles concerning the development, improvement, validation and/or extension of application of analytical methodology in the plant sciences. The spectrum of coverage is broad, encompassing methods and techniques relevant to the detection (including bio-screening), extraction, separation, purification, identification and quantification of compounds in plant biochemistry, plant cellular and molecular biology, plant biotechnology, the food sciences, agriculture and horticulture. The Journal publishes papers describing significant novelty in the analysis of whole plants (including algae), plant cells, tissues and organs, plant-derived extracts and plant products (including those which have been partially or completely refined for use in the food, agrochemical, pharmaceutical and related industries). All forms of physical, chemical, biochemical, spectroscopic, radiometric, electrometric, chromatographic, metabolomic and chemometric investigations of plant products (monomeric species as well as polymeric molecules such as nucleic acids, proteins, lipids and carbohydrates) are included within the remit of the Journal. Papers dealing with novel methods relating to areas such as data handling/ data mining in plant sciences will also be welcomed.
