EFFECT OF SEA BUCKTHORN (<i>HIPPOPHAE RHAMNOIDES</i> L.) BERRY EXTRACTS ON THE ACTIVITY OF LIPASE AND LIPOXYGENASE
Bibliographic record
Abstract
ABSTRACT The inhibitory effect of various extracts (lipophilic, hydrophilic‐EtOH and hydrophilic‐MeOH) from berries of six sea buckthorn cultivars, grown in North‐Eastern Poland and Byelorussia, on lipase and lipoxygenase activities was investigated. The total content of carotenoids in lipophilic and hydrophilic‐MeOH extracts ranged from 293 to 816 mg/100 g and from 5.35 to 6.89 mg/100 g, respectively. β‐Carotene comprised between 84.3 and 95.6% of total carotenoids. The hydrophilic‐MeOH extracts were rich sources of phenolics, but lower quantities of phenolics were also detected in both lipophilic and hydrophilic‐EtOH extracts. The content of vitamin C in hydrophilic‐EtOH extracts was 93–406 mg/100 g. Lipase activity was reduced by 40–70% and 13–50% by lipophilic and hydrophilic‐EtOH extracts, respectively. The effect of hydrophilic‐MeOH extract on lipase activity was negligible. The inhibitory effect of sea buckthorn extracts on lipoxygenase activity was even greater than those exerted on lipase activity.

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.
