Abstract

This study investigated the antidiabetic activity of the aqueous extract of the leaves of Ageratum conyzoides. Streptozotocin induced hyperglycemia male adult albino rats were used to study the antidiabetic effect of Ageratum conyzoides aqueous extract (at doses of 100, 200 and 300 mg/kg respectively). The diabetic rats were housed in metabolic cages, for the whole period of the experiment. Body weight was evaluated at the beginning of the experiment and on days 7, 14, and 21 afterward. Water intake, food intake and urine excretion volume were also estimated. At the end of the experiment the rats were sacrificed and serum insulin concentration, total serum proteins and hepatic glycogen content were estimated. Lipid profile (total cholesterol (TC), High density lipoprotein (HDL)-cholesterol, low density lipoprotein (LDL)-cholesterol and triglycerides (TG)) were also assessed. The results showed significant effect of stimulating body weight growth at the doses of 200, 300 mg/kg. The effect of the extract on the food, water intake and water excretion showed a significant decrease in the 200 and 300 mg/kg extract treated groups. In treated rats, both doses (200 and 300 mg/kg) induced a significant reduction in serum glucose and the Area Under the glucose Curve, with concomitant increases in serum insulin and protein levels. Furthermore, A. conyzoides treatment improve lipid profile by increase HDL and reducing triglycerides and LDL at 200 mg/kg. The present study clearly indicates that Ageratum conyzoidesaqueous extract leaves exhibited significant antidiabetic activity and supports its uses in traditional medicine.

Fractionation and Identification of Phenolic Compounds from Ethylacetate Fraction of Ageratum Conyzoides Methanolic Leaf Extract

“…It is frequently referred to as "horny goat weed." A. conyzoides is used in conventional medicine to treat a number of illnesses, including diabetes [8]. For instance, ethyl acetate extracts have been demonstrated to have anticancer and free radical scavenging activities, while aqueous extracts of the entire plant have been utilized as dermatological treatments [9].…”

“…A phytochemical screening showed that the roots of this plant extract contained various bioactive components such as flavonoids, saponins, tannins, terpenoids, alkaloids, coumarins, chromenes, benzofurans, sterols, terpenoids, and cardiac glycosides, but have been shown to contain no anthracene derivatives [11][12][13][14]. Additionally, antifungal substances such as precocene II and polymethoxy flavones have been found in A. conyzoides [8]. Due to reports of high levels of phenols and flavonoids in A. conyzoides leaf extracts and as a follow-up to work Ozioko et al [11] (which claimed that the ethyl acetate fraction of the methanolic leaf extract of A. conyzoides has a high total flavonoid and phenol content as well as excellent antioxidant and antidiabetic effects), the goal of the current study was to fractionate and identify phenolics from the ethyl acetate fraction.…”
