Studysummary This study developed a reliable UHPLC-MS/MS method to measure flavonoids from Pinus massoniana needles in rat plasma for pharmacokinetics, aiding further research on their potential use in external preparations to prevent hair loss. Our plain-language summary of this paper — not a Tressless recommendation.
A UHPLC-MS/MS method was developed to quantify taxifolin, quercetin, and catechin in rat plasma after administering Pinus massoniana needle extracts, traditionally used in China to prevent hair loss. The method showed good linearity (r² > 0.99), accuracy, precision, and stability. It was successfully applied to pharmacokinetic studies in healthy rats, both orally and transdermally, providing a foundation for further research on pine needle extract as an external preparation.
