Background: The genus of Sterculia has the main compound of phenol and flavonoids. 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 Sterculia: Sterculia rubiginosa Zoll. ex Miq., Sterculia comosa (Wall) Roxb., Sterculia parkinsonii F. Muell, Sterculia macrophylla Vent, Sterculia Stipulata Korth. The simplisia were leaves and woods. Materials and Methods: 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. Sterculia comosa (Wall) Roxb., Sterculia macrophylla Vent, Sterculia Stipulata Korth., have arginase inhibitory activity. Results: 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, Sterculia stipulata Korth., wood, and leaves. The methanol extract of Sterculia comosa (Wall) Roxb. Woods has the highest content of total phenols, antioxidant activity, and arginase inhibitory activity. The methanol extract of Sterculia macrophylla Vent. has the highest content of total flavonoids, but this extract as an arginase inhibitory activity more lower than Sterculia comosa. The active extract as an arginase activity was methanol extract of Sterculia comosa (Wall) Roxb. Conclusion: The total phenols were more contributed for the response of the arginase inhibitory activity much more than antioxidant activity and total flavonoids.

Objective: The purpose of this study is to investigate arginase inhibition, antioxidant activity, total phenolic content and total flavonoid content of ethyl acetate extract of Caesalpiniaturtuosa Roxb. Material and method: stem bark of Caesalpiniaturtuosa Roxb was extracted using hexane, ethyl acetate and methanol subsequently. The ethyl acetate extract was fractioned. Then, the fractions were subjected to arginase inhibition, antioxidant activity, total phenolic content and total flavonoid assay. Correlation was considered by statistical analysis. Result: Out of eight fractions, two fractions have no activity. Two fractions (3 and 6) have strong activity in arginase with inhibition 90.72 \% and 91.41\% respectively. Fraction 3 and 6 have strong antioxidant activity with IC50 25.98 μg/mL and 48.01 μg/mL respectively. Statistical analysis shows arginase inhibitor activity was not related with antioxidant activity, total phenolic content and total flavonoid content in this plant. Conclusion: Activity in arginase inhibition of fraction from ethyl acetate extract of Caesalpiniaturtuosa Roxb are not related to antioxidant, total phenolic and flavonoid content.

Background: Achyranthes aspera, or commonly called as Sangketan in Indonesian is a wild plant that is used as a traditional medicine. The roots of Sangketan can be used as a wound healer by involving the role of arginine and its metabolites, nitric oxide, that directly affect the wound healing process itself. Objective: The aim of this study is to determine the potential of Sangketan roots extract in inhibiting arginase activity. Methods: The roots were extracted using multistage ultrasound-assisted extraction method with n-hexane, ethyl acetate and methanol solvent. Each extract from different solvents was tested for the inhibition of arginase activity using a microplate-based colorimetric method, followed by determination of total phenolic concentration and total flavonoid concentration. Results: The results of inhibition test of arginase activity by n-hexane, ethyl acetate and methanolic extracts were 9.56; 17.58; and 29.77\% sequentially/respectively at concentration of 100 μg/ml; the total phenolic concentration were 3.91; 4.83; dan 11.18 mgGAE/g of sample respectively; and the total flavonoid concentration are 0.29; 0.80; and 0.88 mgQE/g of sample respectively. Conclusion: From this research, it can be concluded that Sangketan roots extract had low potency of arginase inhibitory activity.

Background: Flavonoids, polyphenolic compounds that are ubiquitous in nature, have been known for their pharmacological as antifungal, diuretic, antihistamin, antihypertension, insecticide, bactericide, antiviral, antioxidant, and enzim inhibitor. Flavanones found in all parts Scutellaria indica, has the ability to inhibit arginase, flavanols found in the seeds of Theobroma cacao L. Previous study showed that Caesalpinia ferrea C. Mart stem bark contains flavonoid compound. Objective: The objective of this study to analyze arginase inhibitory activity and to determine the total flavonoid content of Caesalpinia ferrea C. Mart stem bark by using AlCl3 colorimetric method. Methods: Dried Caesalpinia ferrea stem barks were refluxed with three different solvent with gradual gradient polarity i.en-hexane, ethyl acetate, and methanol. Each extract was tested to determine arginase inhibitory activity. Total flavonoid content was determined on extract showed the highest arginase inhibitory activity. Results: Methanolic extract showed arginase inhibitory activity of 12.81\% and flavonoid content was 2 mgQE/g. Phytochemical screening on Caesalpinia ferrea stem bark ethyl acetate extract showed that it contains flavonoids, tannins, saponins, steroids, and terpenoids, meanwhile Caesalpinia ferrea stem bark methanolic extract contains flavonoids, tannins, saponins, and steroids. Conclusion: Caesalpinia ferrea C. Mart stem bark extracts were not potential to inhibit arginase.

Objective: The purpose of this study was to investigate the arginase inhibitory activity, antioxidant activity, and also pharmacognostical study of Sterculia macrophylla leaves. The main component of genus Sterculia was flavonoid that was well known to demonstrate arginase inhibitory activity. Methods: Sample was extracted gradually using n-hexane, ethyl acetate, and methanol solvents, subsequently. The n-hexane, ethyl acetate, and methanol extract were determined for their arginase inhibitory activity. The most active extract was methanol extract. This extract was determined for its antioxidant activity, arginase inhibitory activity, identification of chemical compound, chromatogram profile and determined the content of total flavonoid. The leaves and powder of Sterculia macrophylla were identified with microscopic and macroscopic evaluation. Results: The most active extract was methanol extract with IC50 114,659 \μg/mL for arginase inhibitory activity and IC50 78.47 \μg/mL for DPPH scavenging activity. The secondary metabolite of methanol extract presence compound of alkaloid, flavonoid, tannin, terpene, and glycoside. The total flavonoid content was 141.10 mg/gram extract. The star-shape trichoma was identified as a specific fragment. Conclusion: The methanol extract of Sterculia macrophylla showed activity as arginase inhibitor and antioxidant.
