Evaluation of antioxidant properties of Thaumatococcus daniellii seeds

Thaumatococcus daniellii is a large rhizomatous flowering herb with height of about 3-4 m having large papery leaves1. Flowers of this plant are pale purple and fruits bear soft crimson color that consists of shiny black seeds1. It is usually referred to as miraculous fruit, miraculous berry, serendipity berry and katamfe as well.

It is actually a non-woody fiber plant and is utilized to supply wood fiber during paper manufacturing process2. This plant is generally termed as “ewe eran” in Southwest Nigeria3 and is famous for producing naturally thaumatin; an internationally traded protein sweetener4. This low-calorie sweet eneris appropriate for patients, suffering with diabetes as it is about 2000 times sweeter as compared tosucrose and this natural sweetener is not harmful in case of diabetes5.

Seeds of this plant are black and hard and impervious and were employed by local communities in medicines to treat pulmonary issues6. Moreover, the jelly present on the seed can also be utilized as an alternative for agar7.

However, according to some investigations, by grinding and mixing the seed of this herbaceous plant to food, positive impacts on sight as well as total wellness of an individual can be observed. But, there is no scientific proof to confirm these claims at present. Many studies have been performed on seeds of T. daniellii, but little was known on the in vivo impact of the seed7,8.

Therefore, considering this situation, scientists conducted a new research to study the antioxidant and biochemical impacts of T. daniellii seeds in the liver as well as kidney of male wister rats9.

For this purpose, seeds were macerated with ethanol and filtrate was concentrated to obtain ethanolic crude extract. Rats were then subjected to oral dose of vitamin C, with 500, 1000 and 1500 mg kg–1 of the extracts for fourteen days. Then, scientists analyzed the antioxidant and biochemical parameters as well as Liver histology9.

This study exhibited that Thaumatococcus daniellii seed is a natural source of antioxidants. Moreover, it was found that the in vivo antioxidant characteristics are favorable in comparison with vitamin C. Conclusively; these seeds can be employed for antioxidant bioactive components for the improving liver as well as kidney ailments.
