Whole-cell receptor binding assays demonstrated that compounds found within the rooibos extracts interact with both estrogen receptor (ER) subtypes, as they displaced radiolabeled E2. Although the extracts were much less potent than E2 in inducing agonism in promoter-reporter luciferase assays, most extracts displayed ERβ selectivity with higher efficacy via ERβ than via ERα. In contrast, extract potencies were generally comparable to ICI-182,780, an ER antagonist, in antagonizing E2, while their efficacies showed no ER-subtype selectivity. The preference of selected water extracts (WEs) to signal via ERβ was apparent in their inability to induce progesterone receptor (<i>PGR</i>) mRNA expression, an ERα-activated gene. Furthermore, the lack of <i>PGR</i> stimulation was consistent with Western blot assay results, where most WEs downregulated PR-B protein expression after shorter treatment times (2 or 4 h) and inhibited E2-induced PR-B protein expression after 24 or 48 h. To our knowledge, this study is the first to report that rooibos possesses antiestrogenic activity.

A two-stage optimization strategy was employed, combining gradient elution refinement with response surface methodology based on a Box-Behnken design to systematically optimize injection volume, column temperature, and flow rate.

When applied to Lonicerae Flos samples from three geographical regions, the method revealed significant variations in chlorogenic acid, neochlorogenic acid, and 3,4-dicaffeoylquinic acid, highlighting its utility for geographical origin tracing and regional quality assessment. Specifically, chlorogenic acid showed a gradual increasing trend from Xiushan and Suiyang to Longhui, whereas neochlorogenic acid and 3,4-dicaffeoylquinic acid reached their highest levels in Longhui samples. Compared with existing methods, the proposed approach demonstrates superior performance with wider analyte coverage, improved separation efficiency, and simplified sample pretreatment.
