Antioxidative activities of galloyl glucopyranosides from the stem-bark of Juglans mandshurica.[Pubmed: 18685223]

Two phenolics, 1,2,6-trigalloylglucose (1) and 1,2,3,6-Tetragalloylglucose (2), isolated from the stem-bark of Juglans mandshurica were evaluated for their antioxidative activities. The results showed that compounds 1 and 1,2,3,6-Tetragalloylglucose exhibited strong scavenging activities against 1,1'-diphenyl-1-picrylhydrazyl (DPPH), 2,2'-azino-bis-(3-ethylbenzenthiazoline-6-sulphonic) acid (ABTS(*+)), and superoxide radicals (O(2)(*-)), and also had a significant inhibitory effect on lipid peroxidation and low-density lipoprotein (LDL) oxidation. The strong superoxide radical scavenging of 1 and 1,2,3,6-Tetragalloylglucose resulted from the potential competitive inhibition with xanthine at the active site of xanthine oxidase (OX). In addition, compounds 1 and 1,2,3,6-Tetragalloylglucose displayed significant lipoxygenase inhibitory activity, the mode of inhibition also being identified as competitive. In comparison, the antioxidative activities of compounds 1 and 1,2,3,6-Tetragalloylglucose, together with gallic acid, indicated that the number of galloyl moieties could play an important role in the antioxidative activity.

Anti-complement activity of constituents from the stem-bark of Juglans mandshurica.[Pubmed: 12843637 ]

Four known flavonoids and two galloyl glucoses isolated from the stem-bark of Juglans mandshurica (Juglandaceae), namely taxifolin (1), afzelin (2), quercitrin (3), myricitrin (4), 1,2,6-trigalloylglucose (5), and 1,2,3,6-Tetragalloylglucose (6), were evaluated for their anti-complement activity against complement system. Afzelin (2) and quercitrin (3) showed inhibitory activity against complement system with 50% inhibitory concentrations (IC(50)) values of 258 and 440 microM. 1,2,6-Trigalloylglucose (5) and 1,2,3,6-Tetragalloylglucose (6) exhibited anti-complement activity with IC(50) values of 136 and 34 microM. In terms of the evaluation of the structure-activity relationship of 3,5,7-trihydroxyflavone, compounds 2, 3, and 4 were hydrolyzed with naringinase to give kaempferol (2a), quercetin (3a), and myricetin (4a) as their aglycones, and these were also tested for their anti-complement activity. Of the three aglycones, kaempferol (2a) exhibited weak anti-complement activity with an IC(50) value of 730 microM, while quercetin (3a) and myricetin (4a) were inactive in this assay system. Among the compounds tested, 1,2,3,6-Tetragalloylglucose (6) showed the most potent anticomplement activity (IC(50), 34 microM).

Inhibition effects of the classical pathway complement of isolated compounds from Quercus glauca.[Pubmed: 21078772]

Four galloyl derivatives isolated from the leaves of Q. glauca, namely 6'-O-galloyl salidroside (1), methyl gallate (2), 1,2,3,6-Tetragalloylglucose (3), and 1,2,6-trigalloylglucose (4). 1, 2, 3 and 4 showed inhibitory activity against complement system with 50% inhibitory concentrations (IC(50)) values of 224 μM, 362.4 μM, 32.3 μM, and 138.3 μM. Among the compounds tested, 1,2,3,6-Tetragalloylglucose showed the most potent anticomplement activity (IC(50), 32.3 μM). This is the first report of the isolation and anticomplement activity from Q. glauca.
