Chemical Composition and Antifungal Activity of Lavender ( <i>Lavandula stoechas</i> ) Oil
Bibliographic record
Abstract
The essential oil of Lavandula stoechas was examined by GC and GC-MS. Discs (5 mmi.d.) of the tested fungi ( Alternaria alternata, Fusarium oxysporum and Botritys cinerea) were inoculated separately onto each assay plate and incubated at 25 o C for 7 days. The oil yield of dried parts (v/dw) obtained by hydro-distillation was 2.9%. Thirty-two compounds representing 98.3% of the essential oil were determined. Linalool (49.9%), linalyl acetate (14.4%), lavandulyl acetate (5.7%), α-terpineol (5.6%), terpinene-4-ol (5.1%), lavandulol (3.7%), ( E)-β-ocimene (2.6%) and ( Z)-β-ocimene (2.4%) were identified as the main constituents of the oil. In addition, both doses of the lavender oil showed varying levels of inhibitory effects on the mycelial growth of tested fungi used in the experiment. The results demonstrated the strongest effect on B.cinerea, followed by A.alternata and F.oxysporum. The inhibitory effect is probably dependent on the concentration of essential oils.

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.
