Antioxidant Effects of Some Ginger Constituents
Hiroe Kikuzaki,Nobuji Nakatani +1 more
TL;DR: The nonvolatile fraction of the dichloromethane extract of ginger rhizomes exhibited a strong antioxidative activity using linoleic acid as the substrate in ethanol-phosphate buffer solution.
Journal ArticleDOI
Identification, Quantitative Determination, and Antioxidative Activities of Chlorogenic Acid Isomers in Prune (Prunus domestica L.)
Nobuji Nakatani,Shin-ichi Kayano,Hiroe Kikuzaki,Keiko Sumino,Kiyoshi Katagiri,Takahiko Mitani +5 more
TL;DR: 4-CQA was identified and quantified in prune for the first time, and relatively high amounts of this isomer were characteristic and each isomer showed antioxidative activities which were almost the same.
Journal ArticleDOI
Antioxidant properties of gingerol related compounds from ginger
TL;DR: The results suggested that the substituents on the alkyl chain might contribute to both radical scavenging effect and inhibitory effect of autoxidation of oils, while inhibitory effects against the AAPH‐induced peroxidated of liposome was somewhat influenced by the alKYl chain length.
Journal ArticleDOI
Antioxidant Activity of Chemical Components from Sage (Salvia officinalis L.) and Thyme (Thymus vulgaris L.) Measured by the Oil Stability Index Method
TL;DR: A new abietane diterpenoid, 12-O-methyl carnosol (2), was isolated from the leaves of sage together with 11 abietan diter penoids, 3 apianane terpenoids, 1 anthraquinone, and 8 flavonoids, which exhibited remarkably strong activity, which was comparable to that of alpha-tocopherol.
Journal ArticleDOI
Antioxidative activity of carbazoles from Murraya koenigii leaves.
TL;DR: The antioxidative properties of the leaves extracts of Murraya koenigii using different solvents were evaluated based on the oil stability index (OSI) together with their radical scavenging ability against 1-1-diphenyl-2-picrylhydrazyl (DPPH).
