Isolation and HPLC-MS analysis insecticidal activity franctions from Japropha curcas fruit shell
Bibliographic record
Abstract
To seek insecticidal activity components from Jatropha curcas fruit shell, using alcohol crude extract of butanol partitioned extract in J.curcas fruit shells as an experimental material in our investigation,and then silica gel chromatography,at same time, separated products of the each stage were carried out by tracking activity,analyzed by HPLC-MS,and the main components of active part were initially identified. The results showed that the concentration of colony WD1 reached 8 g·L-1,Myzus persicae and Pieris rapae corrected mortality exceeded 70% in 24 h(72 h),which showed that toxic activity was very high. Through the analysis of WD1 by HPLC-MS,seven compounds with maximum contents were identified,with total amount up to 80.72%. They were 2α,3a,23-Trihydroxyurs-12,20(30)-dien-28-oi,Cyclgrossine B,Vitexin,Diterpene ,Jatrophlone A,Curcusone A or Curcusone B.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
