Abstract. a-tocopherol in in viva has the strangest antiaxidant activity amang ather farms of tocopherols, such as /3, }, and b This is due to. its ability in transferring hydragen ian tofree radicals, sa thefree radicals are stable. During oxidation pracess, a-tocopherol generates radikal tacapheraxyl that is cansidered to [unction as prooxidant. One of stableform of a-tocopherol is a-tocopher…
Background: The increase in the homocysteine levl is related to the heightening of blood pressure and hypertension risk. Hyperhomocysteinemia encourages the production of free radical which can oxidize lipid. Lipid peroxidation can be prevented by several antioxidant such as vitamin C and E. Objective: This study is aimed at finding out the nature of the interaction effect between homocysteine …
Abstract: Formulation of lozenges containing: A) green tea extract; B) green tea extract with sodium ascorbate; and C) green tea extract with grape seed extract have been carried out. Antioxidant activities were compared to the activity of raw active materials. Lozenges were tested for physical characteristics, hedonic values, dissolution rate, and stability during storage. Physical tests indic…
Abstract: Synthesis of I ,S-bis(3' -etoxy-4' -hydroxyphenyl)-I ,4-pentadiene-3-on (EHP) by aldol condensation method from ethyl vanilin and acetone, using hydrochloride acid as a catalyst, has been conducted. Identification of the EHP compound was done through interpretation of UV- Vis, FT-IR, GC-MS and NMR data. The antioxidant activity of EHP (ICso 8.66 ug/ml.) is higher than curcumin (ICso 1…
The production of free radiacals (oxidants) that are not in balance with antioxidant activity can cause cell damage. The need for antioxidant is absolutely necessary not only endogenous but also exogenous. Yellow soybean is one of the plants that have antioxidant activity, which can reduce the effects of free radicals while vitamin E is a powerful antioxidant which is used. This study aims to d…
The stem bark of Garcinia moluensis Lauterb afforded a benzophenone epicambogin (1). The structure was elucidated using IR, MS, NMR spectroscopy and comparison of its spectroscopic data with data reported in the literature. This compound was tested for its bioactivity as antioxidant and toxicity test. The antioxidative activity was evaluated using 1,1-diphenyl-2-picrylhydrazyl (DPPH) method. T…
