Background: Resveratrol is a non-flavonoid polyphenol possesses many biological properties with great potential to develop into various products. In order to cure a wide variety of diseases, resveratrol has attracted a great deal of attention for medicinal purposes. Objective: The present review aimed to provide a comprehensive literature summary of latest scientific evidences on the chemistry, biological properties and therapeutic potentials of resveratrol. Methods: To complete this review, relevant literatures were collected from several scientific databases, including Google Scholar, Pubmed and ScienceDirect, using keywords {\textquotedblleft}source{\textquotedblright}, {\textquotedblleft}chemistry{\textquotedblright}, {\textquotedblleft}bioavailability{\textquotedblright}, {\textquotedblleft}pharmacokinetics{\textquotedblright}, {\textquotedblleft}isolation{\textquotedblright}, {\textquotedblleft}anticancer{\textquotedblright}, {\textquotedblleft}analgesic{\textquotedblright}, {\textquotedblleft}antiinflammatory{\textquotedblright}, {\textquotedblleft}antidiabetic{\textquotedblright}, {\textquotedblleft}nephroprotective activity{\textquotedblright}, {\textquotedblleft}neuroprotective activity{\textquotedblright}, {\textquotedblleft}antiobesity{\textquotedblright}, {\textquotedblleft}cardioprotective effects{\textquotedblright}, {\textquotedblleft}antioxidant{\textquotedblright}, {\textquotedblleft}anti-aging{\textquotedblright} with resveratrol. After a detailed screening process for inclusion and exclusion, the information obtained was summarised. Results: The information on the source, chemistry, bioavailability, biological and therapeutic potentials of resveratrol were tabled. In various pathological conditions, resveratrol can be considered as powerful antioxidants along with multidimensional molecular targets such as NF-ҡB, MAPK, AMPK, SIRT-1, Nrf-2, m-TOR, PI3K/Akt and PPAR-γ signaling pathways. Conclusion: Based on the existing knowledge, we may believe that resveratrol has a significant therapeutic potential for the treatment of various diseases. To accelerate the development and utilization of resveratrol as promising products, in-depth studies should be focused on exploiting its properties and developing phytopharmaceuticals.

Background: Ionizing radiation, such as gamma irradiation, serves as a useful approach to inhibit spore germination and to control pathogens in postharvest seeds. Recently, its application on phytochemical sources and its influence on antioxidant activity of various phytochemical compounds has become an interesting topic to be explored. Objective: The objectives of this study were to determine the effect of gamma irradiation as sterilization method on the resveratrol content and its antioxidant, HMG-CoA reductase inhibitory and dipeptidyl peptidase-4 (DPP-4) inhibitory activities of Melinjo (Gnetum gnemon) seeds. Methods: In this research, melinjo seeds were irradiated by 0.0; 2.5; 5.0; 7.5; and 10.0 kGy with gamma irradiation and then extracted with ethanol. The extracts were tested for resveratrol content with HPLC, antioxidant activities by DPPH assay, HMG-CoA inhibitory activity using HMG-CoA reductase assay kit and DPP-4 inhibitory activity using DPP-4 Inhibitor Screening Assay Kit. Gamma irradiation has effect on resveratrol content, antioxidant activity, HMG-CoA reductase inhibition and DPP-4 inhibitory activity. Results: From the research, the highest value of resveratrol content is 0.18{\textpm}0.004 mg/g seeds powder found in 5.0 kGy gamma irradiation treatment with IC50 94.64{\textpm}0.236 μg/mL, while the highest HMG-CoA reductase inhibition is shown in 2.5 kGy irradiation dose. Melinjo seeds irradiated by 2.5 kGy gamma irradiation also shown a significant increase of DPP-4 inhibition activity. Conclusion: This study suggests that 2.5-5 kGy radiation is the effective gamma irradiation dose to improve the quality of melinjo seeds.

Thus present research work deals with the development and evaluation of topical photo protective formulation, containing antioxidant, wound healing, anti-inflammatory and rather photo protective poly phenols like curcumin, quercetin, resveratrol and safranal. The present research work provides stable natural photo protective formulation with antioxidant potential, high SPF and more important uniform UVA/UVB protection.

Introduction: The fetal programming hypothesis states that conditions during pregnancy, including stress, will have long-term effects on adult health, probably via epigenetic mechanisms. Methodology: Pregnant rats were subjected to restrain stress either during early or late pregnancy with and without resveratrol. Blood and liver tissues were collected from 40 days old offsprings of the above rats to study the prenatal effect on corticosterone, and stress development. Results: It was found that levels of corticosterone advanced protein and lipid oxidation products, GSHRx, increase significantly in offsprings of stressed rats and decreased on intervention with resveratrol, whereas total antioxidants, vitamin C, GSH, SOD and Na+K+- ATPase decreased with stress and increase on resveratrol intervention as compared to controls. Conclusion: The alterations may be due to the effect of stress on HPA axis. Results also support the prevention/protective effect of resveratrol on oxidative stress and may be used as a measure to prevent the metabolic changes in adult life due to prenatal stress.
