alpha hederin/キヅタ属

The influence of alpha-hederin (a saponin isolated from Hedera helix), chlorophyllin, the sodium-copper salt of chlorophyll, and ascorbic acid (vitamin C) on the direct clastogenicity of doxorubicin (Adriamycin) was investigated in vitro in human lymphocytes for the induction of micronuclei. In

We report one fatal case of asphyxia caused by leaves of common ivy. Macroscopic examination of the corpse during the autopsy disclosed an incredible quantity of leaves of Hedera helix in the mouth and throat of the decedent. In order to rule out the possibility of poisoning by the toxic saponins

In this work, we have analysed the effects of alpha-hederin, a monodesmosidic triterpenoid saponin isolated from Hedera helix, on mouse B16 melanoma cells and non-cancer mouse 3T3 fibroblasts cultured in vitro. Our results indicate that, in a serum-free medium, alpha-hederin is cytotoxic and

Leaf extracts of Hedera helix L. are widely used in the treatment of upper respiratory diseases. The saponins a-hederin and hederacoside C are considered to be the main compounds responsible for the biological activity. a-Hederin and hederacoside C were determined in H. helix leaf extracts using a

BACKGROUND The dry extract of Hedera helix leaves, due to its secretolytic and antispasmodic effects, is commonly used to produce pharmaceuticals applied in case of cough and other respiratory symptoms. The results of some in vitro studies as well as the clinical signs of poisoning caused by Hedera

α-hederin, a saponin that is a major constituent of English Ivy (Hedera helix) is effective in the treatment of asthma. In the present study, the effect of α-hederin on lung tissue pathology and the levels of the inflammatory mediators; IL-2 mRNA, IL-17 mRNA, and MicroRNAs (miRNA)-133a was evaluated

alpha-Hederin, a saponin isolated from Hedera helix (L.) (Araliaceae), was tested on Candida albicans ultrastructure. The concentrations used were 6.25, 12.5, and 25 micrograms ml-1 for an exposure time of 24 h. Transmission electron microscopy observations indicated that compared with untreated

The leaves of common ivy (Hedera helix) contain the cytotoxic saponin α-hederin, which is inhibitory to Candida albicans at low concentrations. To investigate the mode of action of α-hederin, a haploinsufficiency screen was carried out using a library of 1152 Saccharomyces cerevisiae deletion

The anti-inflammatory potential of alpha-hederin (monodesmoside) and hederasaponin-C from Hedera helix, and hederacolchisides-E and -F (bidesmosides) from H. colchica was investigated in carrageenan-induced acute paw edema in rats. Saponins and indomethacin were given orally in concentrations of

The antioxidant activities of alpha-hederin and hederasaponin-C from Hedera helix, and hederacolchisides-E and -F from Hedera colchica were investigated, in this study. The antioxidant properties of the saponins were evaluated using different antioxidant tests: 1,1-di-phenyl-2-picryl-hydrazyl

Hederacoside C, alpha-hederin, and hederagenin are saponins of dry extracts obtained from the leaves of ivy (Hedera helix L.). Internalization of beta(2)-adrenergic receptor-GFP fusion proteins after stimulation with 1 microM terbutaline was inhibited by preincubation of stably transfected HEK293

Pathogenesis of neurodegenerative diseases such as Parkinson's disease (PD) and Huntington's disease (HD) are closely related to the formation of protein aggregates and inclusion body. For instance, active autophagic components from Chinese herbal medicines (CHMs) are highlighted to modulate

Colon cancer is the third most frequently diagnosed malignancy and has high morbidity worldwide. Epithelial-mesenchymal transition (EMT) has been increasingly implicated in colon cancer progression and metastasis. The present study was aimed to evaluate the potential antitumor activity of α-hederin,

Ivy (Hedera helix L., Araliaceae), is an evergreen medicinal and ornamental plant. Depending on leaf polymorphism different shaped ivy leaves were extracted and subsequently analyzed by reversed-phase high performance liquid chromatography (RP-HPLC). Quantitative determination of its most prominent

BACKGROUND The long tradition of using the dry extract of Hedera helix (common ivy) leaves in traditional and contemporary alternative medicine caused that many biological and pharmacological studies have been aimed at evaluating the effects of ivy. Some of the results suggest that Hedera helix
