Terminalia ferdinandiana (Kakadu plum) is a native Australian fruit. It is also called Billygoat Plum, Gubinge, Murunga, Guruma, etc. Indigenous Australians have been using this plant as food and medicine for centuries. Kakadu plums are better known for their Vitamin C content, but it also comes with a bunch of other nutritional elements. It is one of the best Vitamin C sources in the world and boasts more than 100 times the vitamin C of an orange and almost five times the antioxidant properties of blueberries.

Health Benefits of Kakadu Plum Beyond Vitamin C:

As the popularity and health benefits of this superfood are increasing around the world, more health-conscious people are trying to add Kakadu plum to their diet. Kakadu Plum is rich in antioxidants like polyphenols, Vitamins C and E, folic acid, and carotenoids. It comes with the same amount of folate found in broccoli (110 micrograms of folate/100 gm) and a fat-soluble antioxidant-Vitamin E 6.1mg/100g DW and 50% of the recommended daily intake.

Kakadu Plum - A Natural Antioxidant 

As many of you may already know, Antioxidants are substances that can prevent or slow damage to cells caused by free radicals, and unstable molecules. Oxidative stress happens when our body cannot process and remove these free radicals efficiently. Oxidative stress is a component linked with many diseases, including atherosclerosis, chronic obstructive pulmonary disease, Alzheimer's disease, and cancer. A study published in the journal Innovative Food Science and Emerging Technologies assessed the antioxidant power of 12native Australian fruits, and found that Kakadu plums had the highestantioxidant capacity among the tested fruits, as determined by Trolox Equivalent Antioxidant Capacity (TEAC) assay.

Anti-Cancer & Anti-Bacterial Properties

The Trolox equivalent antioxidantcapacity (TEAC) assay measures the antioxidant capacity of a given substance,as compared to the standard, Trolox (A water-soluble antioxidant, which wassynthesized as a vitamin E derivative has been used as a standard antioxidantfor these antioxidant capacity assays).  When the researchers used the Photochemiluminescence (PCL) assay (Determine the antioxidant capacityusing an automated photo chemiluminescent system which measures the capacity toquench free radicals), Kakadu plums ranked second after Tasmanian pepper.

 Kakadu plum shows values of 204.8 Trolox equivalents/ compared to blueberries’ antioxidant TEAC value of 39.45 Trolox equivalents/g. 

A study published in the journal Nutrition and Cancer found that polyphenols extracted from Kakadu plums had significant inhibitory activity against cancer cell lines. The study examined polyphenols extracted from selected native Australian fruits—Illawarra plum, Kakadu plum, muntries, and native currant for antiproliferative activity against a panel of cancer and normal cell lines.
The February 2011 issue of the 'Pharmacognosy' Journal reported that the Kakadu plum extracts have strong anti-bacterial and anti-microbial properties. A deionized water extract of Kakadu plum, for example, inhibited the growth of 11 of the 14 bacteria tested (79%).
