Abstract
Abstract Background This study investigated the in vitro antidiabetic, antioxidant, antibacterial, anti-inflammatory and antiproliferative effects of B. strigosa hydrophilic (BSTR) and lipophilic (LSB) leaves extracts. The phytochemical profile was also performed using UHPLC–ESI–QTOF–MS. Results The results indicated that BSTR and LSB showed excellent antioxidant properties in the DPPH scavenging, ABTS scavenging, FRAP and MCA assays. The extracts also demonstrated α-glucosidase (81.56–157.56 µg/mL) and α-amylase (204.44 µg/mL) inhibitory activities. In addition, the extracts showed significant cytotoxic and antiproliferative effects against oral squamous carcinoma (CLS-354/WT) cancer cells. Furthermore, the extracts showed excellent antibacterial activity against Listeria monocytogenes , Vibrio parahaemolyticus , Escherichia coli , Pseudomonas aeruginosa and Staphylococcus aureus . Both extracts exhibited a significant reduction in nitric oxide secretion against activated macrophage cells. The UHPLC–MS analysis revealed that B. strigosa is rich in terpenoids, iridoid glycosides, flavonoids, and phenolic compounds. The plethora of these compounds may be responsible for the observed activities. In addition, the bioactive compounds identified by UHPLC–ESI–QTOF–MS were analyzed using silico molecular docking studies to determine the binding affinity with α-amylase and α-glucosidase. Conclusions These results suggest that B. strigosa is an excellent pharmacological active plant and it provides the basis for further studies on the exploration of its potentials in oxidative stress induced disorders.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
