The secondary metabolites which have an arginase inhibitory activities were phenol and flavonoids. The aim of this study was to investigate the arginase inhibitory activity from genus Sterculia. The Plant of&lt;em&gt; Sterculia: Sterculia rubiginosa Zoll.&lt;/em&gt; ex Miq., &lt;em&gt;Sterculia comosa &lt;/em&gt;(Wall) Roxb., &lt;em&gt;Sterculia parkinsonii&lt;/em&gt; F. Muell, &lt;em&gt;Sterculia macrophylla &lt;/em&gt;Vent,&lt;em&gt; Sterculia Stipulata Korth. &lt;/em&gt;The simplisia were leaves and woods. &lt;strong&gt;Materials and Methods:&lt;/strong&gt; The simplisia were extracted with n-hexane, ethyl acetate and methanol. The ethyl acetate and methanol extract determined the arginase inhibition activity. The active extracts as an arginase inhibitory, determined the total flavonoids, total phenols and antioxidant activity, and the chemical content. &lt;em&gt;Sterculia comosa&lt;/em&gt; (Wall) Roxb., Sterculia macrophylla Vent, &lt;em&gt;Sterculia Stipulata Korth.&lt;/em&gt;, have arginase inhibitory activity. &lt;strong&gt;Results: &lt;/strong&gt;The ethyl acetate extracts of Sterculia Stipulata leaves is an active extract. The methanol extract which have an arginase inhibitor activity were Sterculia comosa (Wall) Roxb. wood and leaves, Sterculia macrophylla Vent., wood and leaves, &lt;em&gt;Sterculia stipulata&lt;/em&gt; &lt;em&gt;Korth., &lt;/em&gt;wood, and leaves. The methanol extract of &lt;em&gt;Sterculia comosa &lt;/em&gt;(Wall) Roxb. Woods has the highest content of total phenols, antioxidant activity, and arginase inhibitory activity. The methanol extract of &lt;em&gt;Sterculia macrophylla &lt;/em&gt;Vent. has the highest content of total flavonoids, but this extract as an arginase inhibitory activity more lower than &lt;em&gt;Sterculia comosa.&lt;/em&gt; The active extract as an arginase activity was methanol extract of &lt;em&gt;Sterculia comosa &lt;/em&gt;(Wall) Roxb. &lt;strong&gt;Conclusion:&lt;/strong&gt; The total phenols were more contributed for the response of the arginase inhibitory activity much more than antioxidant activity and total flavonoids.&lt;/p&gt;

(Black seed), is commonly used by traditional healers as a remedy for more than four thousand years. The antidiabetic property of &lt;em&gt;N. sativa&lt;/em&gt; seeds oil is attributable to the presence of Thymoquinone (TQ). On the other hand many studies have been designed to investigate the possible effects of the TQ in Streptozotocin (STZ) and nicotinamide (NA)-induced diabetes in rats. &lt;strong&gt;Aim of the study: &lt;/strong&gt;The aim of this study was to elucidate the mechanisms underlying the glucose lowering effects of thymoquinone. &lt;strong&gt;Methods:&lt;/strong&gt; &lt;em&gt;In vitro&lt;/em&gt; and &lt;em&gt;in silico&lt;/em&gt; using glycogen phosphorylase (GPa) enzyme assay and docking tools were used. &lt;strong&gt;Results:&lt;/strong&gt; Oral administration of TQ for 60 days, dose dependently improved the glycemic status in STZ-NA induced diabetic rats. GPa activity was measured in the direction of glycogen synthesis by the release of phosphate from glucose-1-phosphate. TQ at a concentration of 0.05 Mm inhibits GPa activity by only 14.9%. &lt;strong&gt;Conclusion:&lt;/strong&gt; These results show that TQ at 60 mg/kg b.w is associated with potential antihyperglycemic effects. Furthermore, anti-diabetic properties of TQ are unassociated with glycogen phosphorylase inhibition.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">6</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">406</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p&gt;&lt;strong&gt;Nahid Mahmoud Hassan El-Ameen&lt;sup&gt;1*&lt;/sup&gt;, Manal Mohamed Elhassan Taha&lt;sup&gt;1*&lt;/sup&gt;, Siddig Ibrahim Abdelwahab&lt;sup&gt;1&lt;/sup&gt;, Asaad Khalid&lt;sup&gt;1&lt;/sup&gt;, Fatima Elfatih&lt;sup&gt;2&lt;/sup&gt;, Mona Awad Kamel&lt;sup&gt;1&lt;/sup&gt; and Bassem Yousif Sheikh&lt;sup&gt;3 &lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;
