Experimentally, the ethylene inhibitor silver thiosulphate increased volatile emission of molecules derived from the terpenoid pathway. Emission of floral volatiles can be regulated by phytohormone and defense signaling molecules. globosa was found to exhibit a diurnal pattern independent of light. The floral volatile emission of this cultivar of G. ![]() The cultivar ‘Fireworks’ has a high abundance of volatile esters such as geranyl propionate, geranyl isovalerate, benzyl isovalerate, and benzyl tiglate. globosa vary in the identity of floral volatiles but the volatile compounds of nonanal, decanal, geranyl acetone, and 4,8,12-tetradecatrienal, 5,9,13-trimethyl, were commonly detected by chromatography-mass spectrometry analysis. These compounds are stored in vacuoles in the plant. The major betacyanins identified in globe amaranth are gomphrenin, isogomphrenin II, and isogomphrenin III. Other flavanols include quercetin, kaempferol, and isorhamnetin derivatives. Gomphrenol derivatives also contribute to phenolic content. A major phenol was found to be kaempferol 3-O-rutinoside based on chromatographic and mass spectrometry techniques. The most abundant phenolic compounds present are flavonoids. globosa including six phenolic acid derivatives and fifteen specific flavonoids. Chemical properties Phytochemicals Īt least twenty-seven phytochemicals have been detected in G. 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. globosa are rich in betacyanins which have a wide range of applications as additives and supplements in the food industry, cosmetics, and livestock feed. globosa has been used in herbal medicine. This plant is common in landscape design and cutting gardens for its vivid colors and color retention. This flower is known as Rakta Mallika in Sanskrit. The flower was included in the gift sent to Britain by Jung Bahadur Rana in 1855. ![]() The flower is said to be introduced in Nepal around 18th century. The slow withering character of the flower symbolizes a long life for the brother. The garland is put around the brother's neck by their sister for protection. In Nepal, the flower is known commonly as m akhamali ful and is used to make a garland during Bhai Tika, last day of Tihar festival. ![]() In Hawaii, it is commonly used in long-lasting leis since it retains its shape and color after drying. Floral volatiles likely play a significant role in the reproductive success of the plant by promoting the attraction of pollinators. Gomphrena globosa is an outcrossing species that is pollinated by butterflies, bees, and other insects. At maturity, the flowerheads are approximately 4cm long and the plant grows up to 24 inches in height. The plant fixes carbon through the C 4 pathway. It is very heat tolerant and fairly drought resistant, but grows best in full sun and regular moisture. globosa blooms continuously throughout summer and early fall. Gomphrena globosa is native to Central America including regions Panama, and Guatemala, but is now grown globally. Within the flowerheads, the true flowers are small and inconspicuous. The round-shaped flower inflorescences are a visually dominant feature and cultivars have been propagated to exhibit shades of magenta, purple, red, orange, white, pink, and lilac. Gomphrena globosa, commonly known as globe amaranth, is an edible plant from the family Amaranthaceae.
