Isolation and characterization of a lectin from Andira anthelmia seeds
Andira anthelmia seeds, a species belonging to the Leguminosae family, Papilionoideae subfamily, Dalbergieae tribe, have a glucose/mannose specific lectin that agglutinates rabbit erythrocytes treated with trypsin. The Dalbergieae tribe has lectins which have specificity for different carbohydrates including mannose and also have several biological activities such as induction of rat paw edema,...
متن کاملAntioxidant and cytotoxic flavonols from Calotropis procera.
Phytochemical investigations of Calotropis procera leaves have led to the isolation of two new compounds: quercetagetin-6-methyl ether 3-O-beta-D-4C1-galacturonopyranoside (3) and (E)-3-(4-methoxyphenyl-2-O-beta-D-4C1 -glucopyranoside)-methyl propenoate (4), along with eleven known metabolites: nine flavonol and two cinnamic acid derivatives. All metabolites were isolated for the first time fro...
متن کاملNew isoflavones and flavanol from Iris potaninii.
Two new isoflavones, 6, 3', 4'-trimethoxy-7, 8, 5'-trihydroxyisoflavone (1), 7, 4'-dimethoxy-8, 3', 5'-trihydroxy-6-O-beta-D-glucopyranosylisoflavone (2), and 5, 3, 3'-trihydroxy-7, 4'-dimethoxyflavanone (3) have been isolated from the underground parts of Iris potaninii along with known isoflavones (4-8) and iriflophenone (9). The structures of the new compounds were determined using NMR and m...
متن کاملNew isoflavones from Iris kashmiriana.
Phytochemical investigation of the rhizomes of Iris kashmiriana (Iridaceae) led to the isolation of three isoflavones characterized by 1D and 2D NMR, IR, UV, and MS as 4'-hydroxy-8-methoxy-6,7-methylenedioxyisoflavone (isonigricin, 1), 5,6-dihydroxy-4',7-dimethoxyisoflavone (isoirisolidone, 2), and 5,7-dihydroxy-4',6-dimethoxyisoflavone (irisolidone, 3). Compound 1 is a new isoflavone, while 2 ...
متن کاملHuman Nutrition and Metabolism Dietary Intakes of Flavonols, Flavones and Isoflavones by Japanese Women and the Inverse Correlation between Quercetin Intake and Plasma LDL Cholesterol Concentration
The intake of flavonols, flavones and isoflavones by Japanese women was calculated from our food-phytochemical composition table. The relationship between intake of these phytochemicals and various anthropometric and blood chemistry data was analyzed in a cross-sectional study. The subjects were 115 women volunteers, aged 29–78 y, living in the northern part of Japan. Each subject completed a 3...
