Checklist of Plants Used as Blood Glucose Level Regulators and Phytochemical Screening of Five Selected Leguminous Species Checklist of Plants Used as Blood Glucose Level Regulators and Phytochemical Screening of Five Selected Leguminous Species

Abstract

In the first part of this study, literature survey of plants recorded to regulate glucose level in blood was carried out. Result of this part includes their chemical constitutes and use in the different body disorders other than diabetes. 48 plants species are collected from the available literature and presented in the form of a checklist. The second part of this work is a qualitative phytochemical screening of seeds selected from the family Fabaceae, namely: Bauhinia rufescens, Senna alexandrina, Cicer arietinum, Lupinus albus, and Trigonella foenum-graecum. The studied plants are extracted in petroleum ether, water, and ethanol and different phytochemicals are detected in the extract. Alkaloids are present in all plants in the different extract, but their concentration is high in T. foenum-graecum and B. rufescens. Glycosides are highly detected in S. alexandrina and L. albus. Flavonoid is highly detected in B. rufescens, Senna and C. arietinum, and L. albus. Phenolic compound is not detected in all extract of the five plants. Saponin is observed in all plant put highly detected in L. albus. Tannin detected in Senna alexandrina. Resins are observed in plants but highly detected in C. arietinum, L. albus, and T. foenum-graecum. Terpenes are observed in all plant put highly in T. foenum-graecum. Protein: results of protein in the studied plant did not give accurate observations as expected. Alkaloids and proteins are the main components known to increase glucose levels in the blood.
