Oxalis corniculata is well known for its medicinal properties like anti-inflammatory, digestive, diuretic, antibacterial, antiseptic etc. The present study focuses on the ability of O. corniculata to alleviate liver damage caused by over dose of paracetamol. Antioxidant activity of O. corniculata was evaluated using the free radical scavenging activity of 1, 1-diphenyl-2- picrylhydrazyl radical...

Cicer Arietinum (Leguminosae) is an annual herb, known as local Indian name ‘Kala Chana’. Its root was extracted using solvents of different polarities and explored for invitro free radical scavenging activity. Preliminary assays of three different extracts of Cicer Arietinum root, scavenges 1, 1-diphenyl-2-picrylhydrazyl stable free radicals in concentration dependent manner. All studied extra...

In vitro antioxidant activities of three sweet dihydrochalcone glucosides from the leaves of Lithocarpus pachyphyllus (Kurz) Rehd. (Fagaceae), trilobatin 2"-acetate (1), phloridzin (2) and trilobatin (3), were investigated. The IC50 (50% inhibitory concentration) values for compounds 1-3 of lipid peroxidation in rat liver homogenate were 261, 28, 88 microM, respectively. Compounds 1-3 increased...

Chemical investigation of the 1-BuOH soluble fraction of the dried fruits of Myrsine seguinii (Myrsinaceae) led to the isolation of five new glycosides, named myrseguinosides A-E (1-5), together with eight known compounds (6-13). The absolute structures of the new glycosides were elucidated by spectroscopic and chemical analyses to be a monoterpene glucoside (1), two flavonol glycosides (2, 3),...

Pemanasan pada suhu dan waktu optimum dapat meningkatkan aktivitas antioksidan madu apis trigona karena meningkatnya total fenolik, flavonoid pigmen coklat. Kemampuan diukur melalui kemampuan menangkap radikal oleh DPPH (1,1-Diphenyl-2-picrylhydrazyl). Tujuan penelitian ini untuk membandingkan perubahan parameter penangkapan serta coklat 5 jenis dari kota Bogor, Kalimantan, Sulawesi, Lombok seb...

Four new flavonoids, 3'-formyl-4',6',4-trihydroxy-2'-methoxy-5'-methylchalcone (1), 3'-formyl-6',4-dihydroxy-2'-methoxy-5'-methylchalcone 4'-O-beta-D-glucopyranoside (2), (2S)-8-formyl-6-methylnaringenin (3), and (2S)-8-formyl-6-methylnaringenin 7-O-beta-D-glucopyranoside (4) were isolated from the buds of Cleistocalyx operculatus (Myrtaceae). The structures of the new metabolites (1-4) were de...

MZ: Meso-Zeaxanthin; L: Lutein; RZ: RR-Zeaxanthin; AMD: Age-related Macular Degeneration; MD: Macular Degeneration; NAFL: Non-Alcoholic Fatty Liver; NASH: Nonalcoholic Steatohepatitis; DPPH: Diphenyl-2-Picrylhydrazyl; ABTS: 2, 2’-Azino-Bis (3-Ethylbenzothiazoline-6-Sulfonic acid); GST: Glutathione-S-Transferase; UDPGT: Uridine Diphosphate Glucuronyl Transferase; SGOT: Serum glutamic oxaloacetic...

Objective: The present study was aimed to find out antioxidant property of methanolic and aqueous extracts of Aegle tamilnadensis Abdul Kader (Rutaceae) leaf. Methods: The phenolic and flavanoid contents of methanolic and aqueous extract were determined. The antioxidant potential of the leaf samples was evaluated by using five in vitro assays such as 2, 2-diphenyl-1-picrylhydrazyl (DPPH), hydro...

Novel rutin-loaded zein-sodium caseinate nanoparticles (ZP) with antioxidant activity in aqueous medium were investigated. The results showed that the sodium caseinate concentrations, dosages of rutin and ethanol volume fractions significantly affected the zein nanoparticles' characteristics. Concerning the antioxidant properties, the highest values of rutin loaded ZP obtained using 2, 2-diphen...
