chrysanthemum zawadskii/항산화물질

The flowers of Chrysanthemum morifolium were extracted by boiling water, and a water-soluble polysaccharide (CMJA0S2) with a molecular weight of 6.5 kDa was isolated by anion-exchange chromatography on a DEAE-cellulose column and gel permeation chromatography on a Sephacryl S-300 HR column.

The relationship between the antioxidant activities and inhibitory effect of 14 Chinese medicinal herbs against oxidized low-density lipoprotein (LDL) formation was evaluated. Prolongation of the lag phase of LDL oxidation depended on the concentration of the herbs. The concentration of each herb

Two new dicaffeoylquinic acids, 3,5-dicaffeoyl- epi-quinic acid (1) and 1,3-dicaffeoyl- epi-quinic acid (2), were isolated from Chrysanthemum morifolium Ramar together with six known dicaffeoylquinic acid derivatives and three flavonoids. The structures of the new compounds were elucidated using of

Chrysanthemum coronarium L. (garland) is an herbaceous plant rich in bioactive compounds. The chemical composition, bioactive compounds and antioxidant properties of a Mediterranean garland population were investigated in different organs at two phenological stages. Antioxidant capacity varied from

OBJECTIVE To study the chemical constituents from the leaves of "Chuju" Chrysanthemum morifolium. METHODS All compounds were separated and purified by column chromatography over silica gel, Sephadex LH-20 and preparative HPLC. Their structures were identified by spectral methods including 1H-NMR and

In order to evaluate the antioxidant and α-glucosidase activities of polysaccharides from Chrysanthemum morifolium cv. Hangju (CMPs), the response surface methodology was applied to optimize the parameters for extraction progress of CMPs by ultrasound, with heat reflex extraction (HRE)

OBJECTIVE In order to provide a scientific fertilizer application for the standardized cultivation, the effects of phosphate (P) fertilizer on the active ingredients and antioxidant activities of Chrysanthemum morifolium were studied. METHODS Pot experiment was adopted to study the effects of P

Chrysanthemum morifolium Ramat is a perennial flowering plant widely cultivated for use in a tea infusion and as a popular beverage. To identify and evaluate the tea infusion made with a γ-irradiated mutant chrysanthemum cultivar with dark purple petals (cv. ARTI-Dark Chocolate), its

The flowers of Chrysanthemum morifolium Ramat. have been used as an herbal tea and in traditional medicine, and the plant has been developed to produce horticultural cultivars of various colors and shapes. In this study, a new chrysanthemum cultivar with dark purple petals (C. morifolium cv.

Liquid chromatography tandem mass spectrometry (LCMS/MS)-based metabolite profiling was applied to elucidate the correlation between metabolite release and antioxidant activity during water blanching of Chrysanthemum coronarium L. (CC). Some major metabolites showing differences between fresh CC and

The essential oil of the Jordanian Chrysanthemum coronarium L. (garland) was isolated by hydrodistillation from dried flowerheads material. The oil was essayed for its in vitro scavenging activity using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) method. The results demonstrate that the oil exhibits

The stability and bioavailability of the major antioxidants in garland (Chrysanthemum coronarium L.), chlorogenic acid, 3,5-dicaffeoylquinic acid and 4-succinyl-3,5-dicaffeoylquinic acid, were investigated together with caffeic acid. These compounds were stable in artificial digestive juice, but

This study investigated the volatile flavor compounds and antioxidant properties of the essential oil of chrysanthemums that was extracted from the fresh flowers of 10 taxa of Chrysanthemum morifolium from three species; namely Dendranthema morifolium (Ramat.) Yellow, Dendranthema morifolium

Chrysanthemum is an important traditional Chinese medicine and is drunk daily as a herbal tea. Chlorogenic acids and flavonoids are generally considered as the bioactive compounds. In this work, six kinds of Juhua Tea were analyzed and their active compounds and antioxidant activities were compared.

Dietary chrysanthemum flower and wolfberry alone or together are widely consumed as a health beverage on a daily basis for centuries. The study aims to evaluate combinative effects of flower heads of Chrysanthemum morifolium cv. Hangju (C) and Lycium barbarum fruit (wolfberry, W) served as tea on
