Comparative discriminant analysis of Mesua ferrea L. and its adulterants.

The Uygur medicinal material Mesua ferrea L. has different plant sources in the market. The flower bud of Mammea siamensis T. Anders, which originated from Myanmar and Thailand, is actually used in the dosage room of Uygur hospitals and pharmaceutical enterprises in Xinjiang Region. On the contrary, flowers of Mesua ferrea L. are less frequently used. In this study, the taxonomic characteristics, liquid chromatography-mass spectrometry (LC/MS) and liquid chromatography (HPLC) were used to compare the similarities and differences between the two species. The results showed that the flowers of the two plants were significantly different in morphology, but the similarity of chemical components was high. At the same time, the study also found that Mesua ferrea L. and Mammea siamensis T. Anders contain a large amount of vitexin and isovitexin, which can be used for qualitative and quantitative research. This study provides a reference for the identification, development and utilization of Mesua ferrea L medicinal materials and the revision of quality standards.
