This UPLC–MS/MS study profiles Styphnolobium japonicum cv. Jinhuai flower buds from Sichuan and Guangxi, China, seeking chemical fingerprints and origin markers for raw-material quality control.
Key findings
- The study reported 1,550 metabolites across 12 classes, dominated by flavonoids. Guangxi samples were richer in lipids and nucleotides, whereas Sichuan samples had more flavonoids and phenolic acids. Three compounds were highlighted as inter-group markers.
Why this matters globally
With replication across seasons, farms and independent samples, the fingerprint could support origin authentication and standardisation of medicinal or functional-food raw materials.
Thai researcher contribution
Leilei Zuo and corresponding author Waralee Watcharin of Assumption University contributed, although all samples and production context were in China.
Limitations to consider
A two-region comparison may confound origin with genotype, season, cultivation and storage. Untargeted annotations need further reference-standard confirmation. Database links to diseases do not establish therapeutic activity, safety or human efficacy.
