Studies on the activities of tannins and related compounds from medicinal plants and drugs. VI. Inhibitory effects of caffeoylquinic acids on histamine release from rat peritoneal mast cells.

Anti-Allergic Effect of a Hot-Water Extract of Quince (Cydonia oblonga)

“…[41][42][43][44][45] These lowmolecular-weight polyphenols are therefore suggested to exhibit have had the anti-allergic effects observed in this study. However, it should be noted that anti-inflammatory polyphenols which inhibit Fc"RI chain expression and IgE production have been found in limited sources other than quince fruits and have a specific structure distinct from the above-mentioned quince fruit-derived polyphenols.…”

Antimutagenicity of Mono-, Di-, and Tricaffeoylquinic Acid Derivatives Isolated from Sweetpotato (Ipomoea batatasL.) Leaf

“…3,4,5-triCQA and 4,5-diCQA have been noted to inhibit HIV replication, 21) and 3,5-diCQA to inhibit the histamine secretion induced by concanavalin A plus phosphatidylserine from rat peritoneal mast cells. 22) Murayama et al 23) have recently identiˆed ChA, 3,5-diCQA, and 4,5-diCQA as antioxidants in edible chrysanthemums. Thus, the caŠeoylquinic acid derivatives can be expected to protect humans from various kinds of diseases.…”

Simple High-yield Purification of 3,4,5-Tri-O-caffeoylquinic Acid from Sweetpotato (Ipomoea batatas L.) Leaf and Its Inhibitory Effects on Aldose Reductase

“…Mono-and diCQAs are ubiquitously present in plants. These components have been reported to inhibit histamine secretion (Kimura et al, 1985), to inhibit HIV integrase (Kwon et al, 2000), to suppress hepatoma cell invasion (Yagasaki et al, 2000), and to act as antioxidants (Maruta et al, 1995). 3,4,5-tri-O-caffeoylquinic acid (3,4, is an ester of quinic acid and three caffeic acids (Fig.…”
