The protein from the seeds of melinjo ( Gnetum gnemon ) was purified using a precipitation method and ion exchange chromatographic techniques to identify the potent antioxidant and free radical scavenging activities. Two antioxidant protein fractions were isolated from G. gnemon seed with molecular
In this study, antioxidant activities and identification of the bioactive substances in Gnetum gnemon L. (Gg) seed hard shell were evaluated. The seed of Gnetum gnemon L., an Indonesian native plant, is commonly consumed as a vegetable or further processed as cracker. Isolated substances from Gnetum
OBJECTIVE
To estimate the prevalence of DR and to correlate cardiometabolic, sociodemographic, and oxidant/antioxidant imbalance data to the prevalence of DR.
METHODS
This case-control study included type 2 DM (T2 DM) patients with DR (n = 66), T2 DM patients without DR (N = 84), and healthy
Introduction:Gnetum ula is a notable medicinal plant used to cure various ailments. The stem part of the plant is used traditionally to treat jaundice and other disorders. The present work is to investigate the in vitro hepatoprotective and antioxidant activity of ethanol
The aim of this study is to evaluate the effects of gamma radiation treatment on three medicinal plants, namely Euodia malayana, Gnetum gnemon and Khaya senegalensis at two different forms; methanol leaf extracts and dried leaves respectively.The microbial Evidence from epidemiological studies has strongly suggested that diets rich in fruits and vegetables play a vital role in disease prevention. The aim of this study was to determine nutrient and antioxidant content for 15 varieties of indigenous vegetables and fruits collected from Southern
A new flavonoid, named 5,7,2'-trihydroxy-5'-methoxyflavone (1), was isolated from the acetone extract of the lianas of Gnetum macrostachyum together with 5,7,4'-trihydroxy-3'-methoxyflavanone (2) and seven known stilbenoids (3-7). The structure of the new compound was determined by interpretation of
Three stilbene trimers (gnemonols D, E, F) were isolated from the root of Gnetum gnemon. The structures were determined by spectroscopic analysis. In addition, the antioxidant activity of the compounds on lipid peroxide inhibition and super oxide scavenging activity were also investigated.
Four stilbene derivatives, gnemonols K and L (resveratrol trimers), M (isorhapontigenin dimer), and gnemonoside K (glucoside of resveratrol trimer) together with eleven known stilbenoids and a lignan were isolated from the acetone, methanol and 70% methanol soluble parts of the root of Gnetum gnemon
This paper describes the isolation and structural determination of a new stilbene dimer, named 7a-epi-gnetin C, from melinjo (Gnetum gnemon L.) seed extract. The relative structure was elucidated based on NMR spectroscopic evidence, while the absolute configuration was assigned by a
Belinjau (Gnetum gnemon L.) seed flour was evaluated for nutritional composition, antioxidant activity and functional properties. Seed flour was found to be rich in protein (19.0g/100g), crude fibre (8.66g/100g), carbohydrates (64.1%), total dietary fibre (14.5%) and encompassed adequate amounts of
Isolated oligostilbenes from G. macrostachyum exhibited sbLOX-1 inhibitory activity with IC50 values ranging from 0.14-11.91 microM. Of these oligostilbenoids, 12 (IC50 0.14 +/- 0.01 microM), 10 (IC50 0.33 +/- 0.11 microM), 11 (IC50 0.49 +/- 0.05 microM) and 7 (IC50 1.03 +/- 0.43 microM) were more
Gnetum parvifolium is a rich source of materials for traditional medicines, food, and oil, but little is known about the mechanism underlying its seed dormancy and germination. In this study, we analyzed the proteome-level changes in its seeds during germination using isobaric tags for relative and
The oxidative damages induced by a redox imbalance cause age-related changes in cells and tissues. Superoxide dismutase (SOD) enzymes play a pivotal role in the antioxidant system and they also catalyze superoxide radicals. Since the loss of cytoplasmic SOD (SOD1) resulted in aging-like phenotypes
As a traditional natural medicine for treating many kinds of diseases, Gnetum parvifolium showed apparent inhibition on xanthine oxidase (XO). In this study, ultrafiltration combined with liquid chromatography-mass spectrometry (LC-MS) is used for the screening of XO inhibitors from Gnetum
