selection of potential indonesian plant species for antioxidant,antimicrobial and antioxidant herbs can be used as complementary therapy in dfu and these properties will be strengthened by silver nanoparticles (agnps). this study was performed for screening of indonesian herbs promising as antioxidant which can be subsequently involved in the green synthesis of agnps.
this study is aimed at determining antioxidant and immunomodulatory activities of 25 select vegetables, herbs, and spices commonly consumed in indonesia. phytochemical profiles were determined by measuring total flavonoid content and 1 h-nmr.
indonesian dtpd (dmpd) for antioxidant and- mdpi
radical scavenging activity of commonly used indonesian vegetables. in this study, ethanolic extracts of vegetables were measured for antioxidant activity using several methods including dpph, superoxide (so) anion, and hydroxyl free radicals scavenging assay.
selection of potential indonesian plant species for antioxidant,phyllanthus niruri and orthosiphon stamineus exhibited the strongest antioxidant power with ic 50 of 102 and 133 μg/ml, followed by curcuma domestica, stelechocarpus burahol, and curcuma xanthorriza with the ic 50 of 363, 481, and 540 μg/ml, respectively.
widely used antioxidant dtpd ( dmpd) for antioxidant
one of the government of indonesia's strategic plans in health is to develop new antidiabetic from nature. in this study, nineteen vegetable species were collected and evaluated for their
evaluation of antioxidant activity using an improved dmpd,ferric reducing power assay, dpph inhibition, and dmpd inhibition assays were used to assess antioxidant activity. qualitative and quantitative phytochemical analysis was done.
review on in vitro antioxidant activities of curcuma species
the antioxidant capacity of samples analyzed by dmpd method lies in a range of values higher and more comparable with those obtained by the abts method.
correlation study of antioxidant activity with phenolic,our approach concluded that c. longa is the greatest source of natural antioxidants among 12 indonesian indigenous zingiberaceae herbs. the use of a mixed-method approach to augment the findings of solitary methods might facilitate future researchers to uncover deeper and hidden meanings.
natural products chemistry of global tropical and subtropical
the existence of volatile oils and oleoresins, and is widely dis-tributed in indonesia. volatile oils or essential oils consist of numerous complex terpenoid mixtures which are widely used in a variety of therapeutic activities: antimicrobial, antiar-thritic, antioxidant, anticancer, antiinflammatory, antidiabetic,
indonesian vegetables: searching for antioxidant,this study aimed to subject nineteen indonesian commonly served vegetables to investigate the in vitro antioxidant activity of their ethanolic extract along with an in silico evaluation of their potential antidiabetic activity.
- How does DMPD + affect antioxidant capacity?
- In this level of concentrations, the antioxidant Trolox is able to transfer a hydrogen atom to the radical cation DMPD Å+ , so the colour of the solution of the radical diminishes proportionally to its concentration (Asghar et al., 2007). These results confirm the capacity of the radical cation DMPD Å+ to evaluate the antioxidant capacity. ... ...
- How does DMPD decolorize a food sample?
- An improved decolorization method for measuring the antioxidant activity of food samples using N,N-dimethyl-p-phenylenediamine (DMPD) is developed. DMPD radical cation (DMPD •+) is generated through a reaction between DMPD and potassium persulfate and is subsequently reduced in the presence of hydrogen-donating antioxidants.
- Can antimicrobial and antioxidant herbs be used as complementary therapy in DFU?
- Antimicrobial and antioxidant herbs can be used as complementary therapy in DFU and these properties will be strengthened by silver nanoparticles (AgNPs). This study was performed for screening of Indonesian herbs promising as antioxidant which can be subsequently involved in the green synthesis of AgNPs.
- Does DMPD scavenge free radicals?
- The free radical scavenging activity as antioxidant of the monoterpenes was evaluated using the stable radical N,N-dimethyl-1,4-phenylenediamine (DMPD) with concentrated 100 mM DMPD solution (Asghar et al. 2007; Badawy et al. 2016;Fogliano et al. 1999). Standard solution of ascorbic acid (50-1000 mM) was prepared in deionized water. ... ...
