An animal study from Dicle University in Turkey, testing goji berry extract as an antioxidant in a surgical ischaemia-reperfusion model.
How the study was done
32 Sprague-Dawley male rats randomised into four groups (control, goji, torsion, torsion-goji). Treatment groups received intraperitoneal goji berry extract before torsion; testes underwent 5 hours of ischaemia and 6 hours of reperfusion. Researchers measured total antioxidant capacity, total oxidant status and oxidative stress index, with histological examination.
What it found
Mean serum total antioxidant capacity was significantly higher in the goji-treated groups, and total oxidant status was significantly higher in the untreated torsion group than in the others.
Limitations worth stating
A rat model of an acute surgical condition, with the extract given by intraperitoneal injection rather than eaten. This is about as far from a dietary context as animal research gets, and it should not be read across to food use.
Why this matters when sourcing goji berries
Frankly, limited relevance to sourcing decisions. We keep it listed for completeness of the literature record rather than because it supports any product positioning.
