Terminalia ferdinandiana, also called the gubinge, billygoat plum, Kakadu plum or murunga, is a flowering plant in the family Combretaceae, native to Australia, widespread throughout the tropical woodlands from northwestern Australia to eastern Arnhem Land.

Its vitamin C concentration may be as high as 1000–5300 mg/100g [1] (compared with 50 mg/100g for oranges), possibly the highest known of any fruit.

It should not be confused with Planchonia careya, with which it shares some common names.

Description[edit]

Terminalia ferdinandiana is a slender, small to medium-sized tree growing up to 32 m in height, with creamy-grey, flaky bark and deciduous pale green leaves. The flowers are small, creamy-white, perfumed, and borne along spikes in the leaf axils towards the ends of the branches. Flowering is from September to December. (Southern hemisphere spring/summer.)

The fruit is yellow-green, about 2 centimetres long and 1 centimetre in diameter, almond-sized with a short beak at the tip, and contain one large seed. They ripen from March onwards.

Uses[edit]

The fruit, now commonly known as Kakadu plum or billygoat plum, is used as bush tucker by the Australian Aborigines. The roundish, light green fruits are usually eaten raw, although they can also be made into a jam.

The Kakadu plum is most notable for its high vitamin C content. Major (Ret.) Les Hiddins of the Australian Army was introduced to them by aboriginals, and had them analyzed by Food Standards Australia, confirming Kakadu plum as an exceptionally rich source of vitamin C.[2]

Kakadu plum is more commonly sold as an ingredient for cosmetics but has possible markets as a nutraceutical in food supplements and fortified beverages. While the fruits have been cultivated and some harvests are now supplying market demand, the vitamin C levels tend to fall with the less harsh growing conditions compared to wild trees.[citation needed]

Folk medicine[edit]

T. ferdinandiana was used as a traditional medicine for the treatment of numerous ailments. The fruits were eaten by Australian Aborigines on long treks or hunting trips and were considered more valuable as a medicine rather than as a food.[3][4][5] The inner bark of the tree was used to treat a variety of skin disorders and infections including wounds, sores and boils.[6] A recent study has reported on the antibacterial activity of T. ferdinandiana.[7][non-primary source needed]
