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.
