Cyperus rotundus cyperaceae: a study of phytochemistry, total polyphenol content, flavonoid content, and antioxidant activity

Abstract

Cyperus rotundus is a folk medicine with many benefits such as anti-inflammatory, anti-cancer, antioxidant, etc. It is widely used in many parts of the world. This study provided data on the phytochemical composition of Cyperus rotundus rhizome, including the active groups of alkaloids, flavonoids, phenols, tannins, and triterpenoids. The polyphenols content in the ethanolic and aqueous extracts of Cyperus rotundus were 26.89 ± 4.33 (mgGAE/g) and 51.84 ± 6.46 (mgGAE/g), respectively. While, the flavonoids content in the ethanolic and aqueous extracts of Cyperus rotundus were 78.03 ± 3.11 (mgQE/g) and 20.28 ± 2.25 (mgQE/g), respectively. According to the ABTS assay, the IC50 values of the aqueous and ethanolic extracts were 117.8 ± 19.85 (μg/ml) and 162.02 ± 11.43 (μg/ml), respectively. According to the DPPH assay, the IC50 values of Cyperus rotundus extracted by water and alcohol were 337.42 ± 22.84 (μg/ml) and 447.53 ± 33.8 (μg/ml), respectively. With the rich presence of secondary compounds, antioxidant activity confirmed in many studies, Cyperus rotundus is evaluated as having potential applications in many different fields such as pharmaceuticals, cosmetics, and functional foods.

The Effect of Using Different Levels of Cyperus Rotundus Tubers in the Diet on the Productive Performance Characteristics of Broilers

“…Through the results, which indicate a significant improvement in live body weight, weight gain, feed consumption and feed conversion efficiency in favor of the Saad treatments compared to the control treatment, this improvement in the productive characteristics is due to the fact that the Saad tubers contain active compounds such as phenols, flavonoids and tannins [27], as flavonoids activate the process of manufacturing the hormone thyroxine and increase metabolic rates as well as support and manufacture proteins to build muscle mass in the body and thus act as growth catalysts by improving metabolism in favor of increasing the growth of muscle tissue [28,29] and this It is consistent with what was mentioned by Fiesel and others [30] that adding the powder of some plant sources rich in polyphenols to the diet as nutritional supplements for chickens can improve the flavor and palatability of the feed, which increases feed consumption and productive performance and increases the physical immunity of the bird. These plants have been proven to stimulate the secretion of digestive enzymes and thus It increases the digestion and absorption of nutrients and thus improves the rate of body growth and the cumulative weight gain due to an improvement in the food conversion factor [31,32] that the improvement in growth is also linked to the improvement of the body's immunity, as these compounds have proven their role as antibiotics for harmful microorganisms, inhibiting their pathogens in the intestine, and bringing about a balance in the intestinal flora [33].…”
