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.

Background: Ki Hampelas (Sterculia rubiginosa Zoll. Ex Miq) is a medicinal plant with antioxidant and nephroprotective activity. Objective: This research aims to prove that Ki Hampelas leaves extract through an acute toxicity test. Materials and Methods: This study used white male rats of the Sprague-Dawley strain divided into four groups, the normal group and the 50 mg/ kg, 1000 mg/kg, 2000 mg/kg dose groups. For the acute toxicity test, a single dose with an observation of 14 days. After that, the surgery was done to see changes in the histopathology of the liver and kidneys. Results: The administration of Ki Hampelas leaf extract in the acute toxicity test did not cause death in the tested animals. There were no significant liver and kidney changes seen from the SGOT, SGPT, creatinine, urea, and histopathology. Conclusion: Ki Hampelas leaves extract did not cause death and toxic effects in the acute toxicity test.

Background: Sterculia has an antioxidant activity. The Sterculia genus has phenols and flavonoids content, and this chemical content may be have an nephroprotective activity. Objective: The study was to investigate the in vitro study of antioxidant activity with DPPH and FRAP study and nephroprotective activity of Sterculia rubiginosa Zoll. Ex Miq. Leaves extract. Materials and Methods: The leaves was extracted using ethanol. This extract was determined for antioxidant activity by in vitro study with DPPH and FRAP methods, determined the content of total phenols, total flavonoids, and also identification of chemical content. Nephrotoxicity study done by induced gentamycin. The groups divided 6 group, consist: negative control, positive control, normal control, and the extract with dose 50 mg/kg, 100 mg/kg, and 200 mg/ kg. The parameter for nephroprotective activity was tubular necrosis, the presence of tubules casts and glomerular damage, creatinine serum, and urea. Results: The ethanol extract has IC50 162.34 μg/ml for DPPH scavenging activity and 18.65 {\textpm} 3.53 FeEAC (Mol/g) for FRAP. The secondary metabolite presence flavonoids, tannins, terpenes, alkaloids, and glycosides. The total phenols 462.36 {\textpm} 9.23 mg GAE/gr, total flavonoids content 59.44 {\textpm} 0.11 mg QE/gr extract. All the dose have an nephroprotective activity, but the best dose was 50 mg/kg. Conclusion: The ethanol extract of Sterculia rubiginosa showed antioxidant activity and nephroprotective activity.

Tithonia diversifolia (Hemsl.) A. Gray is one of the plants used in traditional medicine and belongs to Compositae family. In different parts of Indonesia, it is commonly known as {\textquotedblleft}paitan and kembang bulan{\textquotedblright}. The study provides an early description of Tithonia diversifolia (Hemsl.) A. Gray) and complete the monographs data extract. This plant prospects to the main source of the raw material for the herb-drug product and some parameters identified were needed to ensure the safety, quality and efficacy of the product. The present study is to evaluate macrosand microscopic characteristic of the Indonesian plant and its quality parameter including fluorescence, physicochemical characteristics and phytochemical screening. Moisture content, ethanol and water-soluble extract was determined, and were discovered to be 11,27\%, 4,73\% and 18,01\%. Total ash value and acid insoluble ash value were determined which was 10.29 and 0.72 \% respectively. Phytochemical screening of aqueous ethanol extract of Tithonia diversifolia showed the presence of alkaloids, flavonoids, tannins, saponins and triterpenoids. The result showed that average content of flavonoid total is 69.1653 mg QE/g extract.
