Abstract
Pogang gan (Curcuma sp., Zingiberaceae family) is medicinal herb and threatened and it is usually used as a tonic. We successfully micropropagated and cultivated this species. This study determined the total alkaloid, polyphenol, flavonoid and saponin contents of its growth time in order to determine harvest time. The highest level of total alkaloid content is roots after 11 months cultivation (0.272 mg/g), total polyphenol content is rhizomes after 11 months (1.71 mg GAE/g), total flavonoid content is rhizomes after 11 months (13.89 mg QE/g) and total saponin content is tubers and roots after 11 months (5.26% and 4.78%). The total content of alkaloid and flavonoid of pogang gan is higher than Curcuma zedoaria. The total saponin content of natural pogang gan is equal to 39.5% of 6-year old Vietnamese ginseng and the saponin content in rhizomes and tubers of 11-month-planted Pogang gan is from 55.5% to 67.8%, compared with natural Pogang gan.

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
