PHYTOCHEMICAL ANALYSIS OF СО<sub>2</sub>-EXTRACTS FROM DAMAGED SEEDS OF WHEAT VARIETY «CANADIAN»
Bibliographic record
Abstract
This article presents the results of qualitative and quantitative analysis of whole and germinated (damaged) seeds of wheat variety «Kanadskaya». An extract was obtained from germinated (damaged) wheat grain by supercritical fluid CO2-extraction. According to the results of phytochemical analysis, carbohydrates, amino acids, flavonoids, and fatty acids were detected in the composition of CO2-extract. Using gas chromatography method, the extract was found to contain 14 fatty acids, most of which were methyl myristate (42,57%), methyl decanoate (25,85%), methyl ester of cis-10-pentadecenoic acid (16,80%) and methyl palmitate (7,35%). No significant difference was observed in the extract obtained from the damaged variety of wheat «Kanadskaya» in comparison with CO2-extract obtained from pure whole grain of wheat «Uralosibirskaya 2». Only the amount of methyl laurate was 4 times less, methyl stearate – 12 times less, methyl ester of cis-10-heptadecenoic acid – 3 times less. On the contrary, in the CO2-extract obtained from damaged wheat, the amount of methyldecanoate was higher by 4,48% and methyl ester of cis-10-pentadecenoic acid by 14,52%. In addition, methylundecanoate, methyl palmitate and methyl behenate of saturated fatty acids were found in this extract, which were not present in the CO2-extract obtained from pure whole wheat grain «Uralosibirskaya 2». It should also be noted that representatives of unsaturated fatty acids were detected in the CO2-extract obtained from the damaged variety of wheat «Kanadskaya». In total, their share amounted to 19,7%. According to the results of capillary electrophoresis, the proportion of vitamin B1 from B vitamins was higher and amounted to 0,13±0,03 mg/100 g; however, compared to the normal amount, this figure was 3 times lower. The proportion of amino acids was also very low, with phenylalanine content being slightly more dominant at 0,098%. Vitamin E content (0,72 mg/100 g) was determined by high-performance liquid chromatography, while vitamin A was absent in the extract.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
