What if the intense red color of a fruit had the ability to destroy cancer cells without harming healthy cells?
A research team from India has shown that betalain and pectin extracted from the fruit of Opuntia dillenii (TINTO FIG®) induce apoptosis (programmed cell death) in tumor cells (Ehrlich ascitic carcinoma line - EAC), without significant toxicity to healthy cells.
What was investigated?
The effect of the following was evaluated:
-
Fruit pectin (extracted from the peel)
-
Fruit pulp
-
Betalain pigment (betacyanins and betaxanthins, isolated from the pulp)
...on tumor cells (EAC) and normal cells (NIH3T3) in cell cultures.
Key results
1. Inhibition of tumor growth
-
All three fractions reduced cell growth in a dose-dependent manner.
-
Betalain (pigment) was the most potent, with an IC50 of 71.9 μg/mL in EAC cells at 48 h.
-
The viability of tumor cells fell to 4.59% after exposure to pure pigment.
2. Induction of apoptosis (programmed cell death)
-
Flow cytometry analysis revealed:
-
78.88% apoptosis with pigment
-
39% with pulp
-
38% with pectin
-
-
Confirmed by:
-
Annexin-V staining
-
Fluorescence microscopy
-
TUNEL assay (DNA fragmentation)
-
3. Safety in normal cells
-
In healthy cells (NIH3T3), no significant toxicity was detected .
-
In the hemolytic assay (human erythrocytes), all extracts produced <5% hemolysis , indicating low cytotoxicity .
Why is this study relevant?
DNA damage-induced apoptosis is one of the most sought-after mechanisms in antitumor therapies. What is surprising about this study is that:
-
The compounds are not synthetic, but extracted from an edible fruit.
-
They act selectively on tumor cells.
-
They do not require complex processing to be active (the betalain was extracted by aqueous and gentle methods).
Implications for functional health
The results suggest that FIGO TINTO®, consumed in concentrated extracts or integrating its active ingredients, could be part of a prevention or adjuvant strategy in cases of tumor risk , especially in functional diets based on bioactive compounds.
At Tuno Canarias, part of this research supports the use of the pigment and fiber of the FIGO TINTO® in antioxidant formulas designed for everyday use:
-
BOOST with FIG RED® – a blend of functional extracts for cellular energy and antioxidant defense

Digestive Creamer – formula with fiber and RED FIG® that supports digestive, immune, and cellular health

HIGO TINTO® Family Max – an alternative to cocoa without sugar, with protective natural pigments

100% Organic Red Fig® Powder – ideal for capsules, smoothies or nutraceutical customization

Conclusion
This study further confirms the antitumor potential of the RED FIG® , especially its pigment (betalain). By inducing apoptosis in malignant cells without affecting normal cells, it positions itself as a strong candidate for natural prevention and support formulas .
The vibrant color of the TINTO FIG® is not just beauty. It's biochemistry with purpose.
