Phytochemical Study of Steroidal Sapogenin “Tigogenin” Present in the Leaves of Yucca aloifolia Cultivated in Iraq
...Show More Authors

This study detects the presence of the most important steroidal sapogenin “Tigogenin” in the leaves of Yucca aloifolia widely cultivated in Iraq. The absence of any study concerning the Tigogenin content of this medicinal plant in Iraq, and the industrial importance of Tigogenin depending on its role as a precursor in the synthesis of some steroidal drugs, acquired this study its value. This study concerned with extraction, identification, isolation, and purification of Tigogenin from the leaves of Yucca aloifolia. Extraction of this compound was carried out using two methods. Identification of this compound was done using thin layer chromatography (TLC) where different solvent systems had been tried. Libermann – Burchard reagent was used for detection. This identification was further augmented by using high performance liquid chromatography (HPLC) and then this steroidal saponin was isolated and purified. The identification of isolated Tigogenin was carried out using melting point (M.P.), Thin layer chromatography (TLC), infrared spectroscopy (IR) and High performance liquid chromatography (HPLC) . This study confirms the presence of Tigogenin in the leaves of Yucca aloifolia cultivated in Iraq. Also the result of this study showed that the second extraction method was the best, because the amount of both extract and Tigogenin were higher than one extraction method.

Key words : Yucca aloifolia , Steroidal saponin , "Tigogenin"

Abstract

Background: The novel coronavirus 2 (SARS?CoV?2) pandemic is a pulmonary disease, which leads to cardiac, hematologic, and renal complications. Anticoagulants are used for COVID-19 infected patients because the infection increases the risk of thrombosis. The world health organization (WHO), recommend prophylaxis dose of anticoagulants: (Enoxaparin or unfractionated Heparin for hospitalized patients with COVID-19 disease. This has created an urgent need to identify effective medications for COVID-19 prevention and treatment. The value of COVID-19 treatments is affected by cost-effectiveness analysis (CEA) to inform relative value and how to best maximize social welfare through eviden

Insulin Resistance in Association with Metabolic Syndrome in Wasit University Students in Iraq
...Show More Authors

In Iraq 1.4 million of people have diabetes, the prevalence of T2DM was ranged (8.5%—13.9%), and the cluster of metabolic abnormalities has long been identified as the risk factors for type 2 diabetes and is now commonly described as metabolic syndrome/MetS. Insulin resistance takes a key role in the process of the MetS and has even been hypothesized as its underlying cause. Clinical and epidemiologic studies also indicate that obesity and life style habit might be correlated with IR. This study examined the relationship between IR and MetS in a sample of young, healthy university students in Iraq. It discovered that the severity of IR is positively correlated with the clustering of MetS risk factors in Iraqi students, suggesting
