What if a desert fruit could fight bacteria, stabilize glucose, and protect cells all at the same time?
A study published in the Journal of Food Quality confirms that ethanolic extracts of Opuntia dillenii (HIGO TINTO®), obtained from the seeds, juice, and skin of the fruit , possess bioactive compounds with potent antidiabetic effects , as well as significant antimicrobial and antioxidant activity. .
What was investigated?
Ethanolic extracts of the following were studied:
-
Seeds
-
Juice
-
Fruit peel
And its properties were evaluated:
-
Antioxidants (polyphenol and flavonoid content)
-
Antidiabetic agents (inhibition of α-amylase and α-glucosidase)
-
Antibacterial and antifungal
Notable chemical composition
Phytochemical analysis revealed high concentrations of polyphenols (up to 341 mg GAE/100 g ) and a rich presence of bioactive compounds such as:
| Compound | Part with higher concentration |
|---|---|
| Gallic acid | Juice (447.6 mg/100 g) |
| Syringic acid | Seeds (252.7 mg/100 g) |
| Quercetin-3-O-glucoside | Seeds (199.6 mg/100 g) |
| Kaempferol | Skin (166.7 mg/100 g) |
| Catechin, naringin, rutin, ferulic acid | Various parts of the fruit |
Potent antidiabetic activity
All extracts significantly inhibited the digestive enzymes responsible for sugar absorption:
-
α-amylase (responsible for the breakdown of starch)
-
α-glucosidase (converts disaccharides into glucose)
The fruit peel extract was the most effective, with activity equal to or greater than that of the standard drug acarbose. .
Furthermore, molecular docking simulations confirmed that compounds such as naringin, catechin, and kaempferol bind strongly to the active site of human α-amylase, even better than the reference drug.
What are the implications?
-
It decreases glucose absorption after meals.
-
Prevents sugar spikes
-
It contributes to glycemic control in people with type 2 diabetes or insulin resistance.
These properties make the RED FIG® an ideal candidate for nutraceuticals and metabolism supplements.
Does it have an antimicrobial effect?
Yes, the juice extract specifically showed activity against:
-
Escherichia coli
-
Salmonella braenderup
-
Listeria monocytogenes
No significant activity was detected against fungi ( Candida spp. ), nor against Staphylococcus aureus. .
Which Tuno Canarias products take advantage of these effects?
-
Digestive Creamer
Sugar-free formula with prebiotic fiber, ideal for improving the digestion of sugars and fats -
BOOST with RED FIG®
Functional blend for energy and active metabolism, with RED FIG® extract, ginger and turmeric -
Organic RED FIG® Powder
100% pure, for inclusion in capsules or customized glycemic control supplements
Conclusion
The study confirms that Opuntia dillenii (TINTO FIG®) is not only notable for its color and flavor. Its extract inhibits key digestive enzymes , reduces glucose absorption , and exhibits antimicrobial and antioxidant properties , supported by both in vitro assays and molecular simulations.
The skin, seeds, and juice of the RED FIG® are not waste. They are active ingredients with a promising future in natural health.
