Background: Acute kidney injury (AKI) is a kidney disease resulting in high morbidity and mortality levels in humans. One of the disorders classified as AKI is ischemia-reperfusion injury (IRI), characterized by two phases. The first phase is Ischemia in the kidneys due to obstruction of the renal arteries or veins, followed by the second phase, which is the occurrence of reperfusion with blood flowing back in the renal arteries veins. The aim of this current research is to analyze the efficacy of Artocarpus altilis on Kidney ischemiareperfusion model rats. Methods: To this end, first, we established Ischaemia-reperfusion kidney injury rat. We then evaluated the Artocarpus altilis extract on IRI model rats. A total of 36 rats have grouped into six groups. Group I is the Sham group, Group II is the negative control group, Group III is the positive control group (vitamin C 100 mg/kg BW), Group IV is Dose I of Artocarpus altilis extract 50 mg/kg BW), Group V is Dose II Artocarpus altilis extract 100 mg/kg BW), Group VI is Dose III Artocarpus altilis extract 200 mg/kg BW). The vitamin C and Artocarpus altilis extract administered 14 days before and after Ischemia-reperfusion treatment. At day 0, Ischemia was made by bilateral renal pedicle clamping method for 30 minutes, sacrificed 14 days after reperfusion. The blood and histology samples were collected on day 0, a day after reperfusion, at 24 hrs after reperfusion, at 48 hrs after reperfusion, and 14 days after treatment. Results: The clamping duration of 30 minutes leads to achieving the most representative clinical IRI conditions. It shows the most significant recovery of injury conditions within the 14-day reperfusion period in IRI animal models, making it ideal for IRI operations for the preliminary test. The administration of 100 mg/kg BW of Artocarpus altilis extract could reduce the malondialdehyde plasma compared with the sham group. The SOD and Catalase activity showed improvement after reperfusion. Conclusion: Artocarpus altilis extracts showed antioxidant activity to prevent the kidney from ischemia-reperfusion injury by modulated SOD and Catalase.

Degenerative diseases such as cancer, heart disease is one of the diseases caused by free radicals. Dengen (Dillenia serrata) is one of Indonesia{\textquoteright}s endemic local plants that has the potential to bind free radicals. So far, only limited to the use of fruit and consumed directly. This study aims to determine the ability of dengen stem bark extract to bind to free radicals expressed in IC50. In the initial research, the total content of polyphenols in dengen stem bark extract was 444.8 mg GAE / g or 44.48\%. Dengen stem bark is extracted by maceration using 70\% ethanol solvent. Antioxidant activity was calculated based on IC50 (Inhibition Concentration) values using the DPPH method, and measured at a wavelength of 516 nm. Ethanol extract of dengen bark is made in 5 concentration series, namely 10 ppm, 20 ppm, 30 ppm, 40 ppm and 50 ppm. Ethanol extract of dengen bark has a very active antioxidant activity with an IC50 value of 48.33 ppm. Whereas for comparison vitamin C has an IC50 value of 15.448 ppm. From the results, it can be concluded that the ethanol extract of dengen bark has the ability to bind free radicals with IC50 48.33 ppm

Introduction: Electron Paramagnetic Resonance (EPR) spectroscopy is a unique technique able to identify and quantify free radicals in the complex biological matrices. In this study, free radical scavenging activity of aqueous and methanol extracts of fruits, shoots and roots of dill and parsley was examined using EPR technique, in addition to the determination of their contents of total polyphenols (TPC) and flavonoids (TFC). Method: The hydroxyl anion scavenging activity (HASA) of the tested extracts was determined using EPR spin trapping technique and hypoxanthine/xanthine oxidase system generating (O{\textbullet}-2). The TPC and TFC were determined using Folin-Ciocalteu and aluminum chloride colorimetric assays. Results: Both aqueous shoot of dill (ADSh) and methanol root of parsley (MPR) demonstrated the strongest inhibition of HASA. On the contrary, the aqueous extract of dill fruit at a concentration of 0.5 mg/ml was found to be pro-oxidant (49.43 \%), but at 10 mg/ml demonstrated potent inhibition of HASA (98.12 \%). TPC was found to be the highest in the methanol extract of parsley fruit (MPF, 88.62 {\textpm} 0.6 mg GAE/g) and the lowest in MPR (4.34 {\textpm} 0.050 mg GAE/g). On the other hand, TFC was the highest in MPF (584.29 {\textpm} 2.10 mg GAE/g) and the lowest in the methanol extract of dill fruit (MDF, 1.28 {\textpm} 0.02 mg rutin/g). Conclusion: In this study, EPR provided a direct insight that all tested apiaceous plants extracts showed effective HASA except two extracts that proved to be pro-oxidant at 0.5 mg/mL This study confirmed that there is no correlation between antioxidant potential and TPC and TFC.

Background: Acacia senegal (Fabaceae) Wild is a leguminous tree with economic values, but its leaves are under-utilised. Objective: To investigate the phytochemical constituents and antioxidant potential of crude extracts from A. Senegal{\textquoteright}s leaves. Methods: Methanol and acetone crude extracts of leaves of A. senegal were prepared by maceration using organic solvents, methanol and acetone respectively. Qualitative and quantitative phytochemical analysis of the crude extracts were evaluated using Association of Agricultural and Chemist (AOAC) protocols. Antioxidant activities of the crude extracts were determined using 2, 2'-azino-bis-(3-ethylbenzothiazoline-6-sulphonic acid (ABTS) and 2, 2-diphenyl-1-picrylhydrazyl (DPPH) respectively. Results: The crude extracts (acetone and methanol) showed vary quality of phytochemical constituent including flavonoid, alkaloids, carbohydrate, saponins, tannin, steroids, and terpenoids. Acetone crude possessed significant (P \< 0.05) higher total flavonoid and proanthocyanidin content in comparison with methanol extracts. Whereas, methanol crude extract possessed significant higher total phenol content compared with acetone crude extract. The crude extracts showed antioxidant activities as evidence in scavenging ABTS and DPPH radicals. However, acetone crude with lower IC50 of 0.09 mg/mL possessed significant higher ABTS scavenging ability compared to methanol (0.07 mg/mL) and ascorbic acid (0.07 mg/mL). Conclusion: The crude extracts could serve as a promising natural antioxidant agent in management of oxidative stress diseases. For further studies, bioactive compounds need to be ascertained.

Introduction: Radicals were compounds that generated in normal metabolism and create cell damage. A significant increase of free radical and decreased radical elimination can lead to oxidative stress. Oxidative stress plays an important role in the development of many diseases. Enhanced supply of antioxidants will help prevent the morbidity of many diseases. Garcinia hombroniana Pierre has potency as an antioxidant, but study to evaluate the active fractions as an antioxidant has not been done. Objective: The objective of the study was to evaluate antioxidant activity of fractions separated from ethyl acetate (EtOAc) and methanol (MeOH) extract of Garcinia hombroniana leaves and to obtain active fractions to facilitate finding a pure antioxidant compound. Methods: The extract was fractionated using column chromatography, while antioxidant activity assay was conducted in vitro using spectrophotometric methods with DPPH and FRAP method. Results: EtOAc extract of G. hombroniana leaves yielded EA-8 with radical scavenging percentage 32.67\% (10 ppm, with DPPH method) and EA-11 with antioxidant activity percentage 25.73\% (10 ppm, with FRAP method) as the most active fraction from EtOAc extract, while MeOH extract yielded M-3 with radical scavenging percentage 37.42\% (10 ppm, with DPPH method) and 26.70\% (10 ppm, with FRAP method) as the most active fraction from MeOH extract Conclusion: Most active fractions has good antioxidant activity, worthy for further study to isolate antioxidant compound which is responsible for antioxidant activity. However, the percentage of radical scavenging or antioxidant activity of all active fractions were smaller than quercetin as a positive control.

Background: Health-benefit properties of natural pigments have been intensely studied, especially the anthocyanins. In the last few decades, research on anthocyanins has attracted biologists by the increasing evidence of their health beneficial effects. Osbeckia, belongs to Melastomataceae and is well-known for colouring pigments and other bioactive compounds. In the present study, total anthocyanin and antioxidant capacity indicators were evaluated from 8 Osbeckia spp. and anthocyanin was extracted from in vitro cultures of O. aspera and O. reticulata. Materials and Methods: The antioxidant effect was studied using ABTS (2, 2\’-azino-bis-3-ethyl benzthiazoline-6-sulphonic acid) radical cation decolourisation assay, the FRAP, the scavenging ability of hydroxyl radicals and the superoxide anion scavenging activity. Anthocyanin extracted from in vitro cultures were purified and fractionated using column chromatography and LC-MS MS analysis. Results: In vitro cultures of O. aspera was obtained in MS medium fortified with various combinations of Benzyl Adenine (BA), Naphthalene acetic acid (NAA) and 2, 4-D. The chromatograms of O. aspera revealed the presence of malvidin-3 -diglucoside, peonidin, delphinidin and cyanindin whereas O. reticulata cultures accumulated large amounts of malvidin, cyanindin and cyanidin aglycone. The purified anthocyanins of these species were evaluated for their antioxidant potential and was found more remarkable than the crude extracts. Conclusion: Osbeckia species are rich in anthocyanin and therefore display potential AOX power. O. aspera and O. reticulata callus was induced in vitro production of anthocyanins. The pool of anthocyanins was purified and fractionated by LCMS/ MS and AOX assays were performed with the purified anthocyanin which showed higher level activities.
