Abstract
Derris is a genus belonging to the Leguminosae family with about 800 species that are widely distributed in tropical, subtropical areas of Asia and Africa [ 1 ]. Published studies have shown that the genus is a rich source of pterocarpans, flavonoids, particularly prenylated isoflavonoids and flavonoids [ 2 – 5 ] and these phytochemicals are associated with a broad spectrum of biological activities, including insecticidal, antimicrobial, cytotoxic, and antioxidant activities [ 3 – 7 ]. As part of a BioBioPha [ http://www.chemlib.cn/ ] objective to assemble a large-scale natural product library valuable in the discovery of new drug leads from nature [ 8 – 10 ], the phytochemical investigation on the twigs and leaves of Derris robusta led to the isolation of four new prenylated isoflavonoids, named derrisisoflavones H–K ( 1 – 4 ), and a new isoflavan, namely 6-hydroxyisosativan ( 5 ). This paper describes the isolation and structural elucidation of five new compounds (Fig. 1 ).

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
