Abstract

fetched live from OpenAlex

Physalis angulata L. is an exotic fruit of the Solanaceae family, native to the Amazon region, which has been widely introduced across many tropical and subtropical regions (e.g. Central and South America, Africa, India and Pacific islands). Often characterized as a pantropical invasive weed of crops, gardens and plantations, it contains several chemical compounds of biological interest, such as phenolic acids and flavonoids. The profiles of soluble and insoluble phenolic acids, total phenolic content (TPC) and antioxidant activity of fruits of Physalis angulata were determined in two stages of maturation in order to expand its consumption. The predominant phenolic acids in ripe and green fruits were ferulic acid and p-hydroxybenzoic acid. During maturation, the TPC increased by 9.8%, resulting in a 10.15% higher antioxidant capacity compared to the green fruits. The ripe fruits exhibited values of TPC and antioxidant activity higher than those found in ripe Physalis peruviana, another fruit of the Solanaceae family, which is already consolidated as a highly functional fruit.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
