Globe amaranth

In Hawaii, it is commonly used in long-lasting leis since it retains its shape and color after drying. In Nepal, the flower is known commonly as makhamali ful and is used to make a garland during Bhai Tika, last day of Tihar festival. The garland is put around the brother's neck by their sister for protection. The slow withering character of the flower symbolizes a long life for the brother. The flower was included in the gift sent to Britain by Jung Bahadur Rana in 1855. This flower is known as Rakta Mallika in Sanskrit. This plant is common in landscape design and cutting gardens for its vivid colors and color retention. The edible plant G. globosa has been used in herbal medicine. The flowers of G. globosa are rich in betacyanins which have a wide range of applications as additives and supplements in the food industry, cosmetics, and livestock feed. Stable between pH 3 and 7, the betacyanins in globe amaranth are well suited to be used as natural food dye and have a red-violet color.

At least twenty-seven phytochemicals have been detected in G. globosa including six phenolic acid derivatives and fifteen specific flavonoids. The most abundant phenolic compounds present are flavonoids. A major phenol was found to be kaempferol 3-O-rutinoside based on chromatographic and mass spectrometry techniques. Gomphrenol derivatives also contribute to phenolic content. Other flavanols include quercetin, kaempferol, and isorhamnetin derivatives.
