A new ferulic acid ester and other constituents from Tamarix nilotica leaves.
Phytochemical investigation of the leaves of Tamarix nilotica (Tamaricaceae) has led to isolation of methyl ferulate 3-O-sulphate (1) for the first time from natural sources. In addition, coniferyl alcohol 4-O-sulphate (2), kaempferol 4'-methyl ether (3), tamarixetin (4) and quercetin 3-O-beta-D-glucupyranuronide (5) were isolated from the n-butanol soluble fraction of the extract. The pentacyc...
متن کاملHydrolyzable Tannins of Tamaricaceous Plants. 7.1 Structures and Cytotoxic Properties of Oligomeric Ellagitannins from Leaves of Tamarix nilotica and Cultured Tissues of Tamarix tetrandra.
Partially unacylated new oligomeric hydrolyzable tannins, nilotinin T2 (1, trimer) and nilotinin Q1 (2, tetramer), together with four known trimers, nilotinin T1 (3) and hirtellins T1-T3 (4-6), and a dimer, tamarixinin B (7), were isolated from the aqueous acetone extracts of leaves of Tamarix nilotica. Among them, the new trimer 1 and the known trimers 4 and 6, in addition to the partially una...
متن کاملMalic dehydrogenase from tamarix roots: effects of sodium chloride in vivo and in vitro.
Soluble and mitochondrial malic dehydrogenases (MDH) were isolated from root tips of the halophyte Tamarix tetragyna L. grown in the presence and absence of NaCl. The activity of the enzymes isolated from root tips grown in the presence of NaCl was lower than that of the enzymes isolated from roots grown in absence of NaCl. The mitochondrial MDH was much more sensitive to salinity than the solu...

15 صفحه اولAntioxidant activity of tea polyphenols in vivo: evidence from animal studies.
Tea is particularly rich in polyphenols, including catechins, theaflavins and thearubigins, which are thought to contribute to the health benefits of tea. Tea polyphenols act as antioxidants in vitro by scavenging reactive oxygen and nitrogen species and chelating redox-active transition metal ions. They may also function indirectly as antioxidants through 1) inhibition of the redox-sensitive t...
