Antioxidant activity of delphinidin and pelargonidin: Theory and practice

Journal of Food Biochemistry, 2022
The quantum chemical density functional theory and in vitro chemical-based antioxidant assays were used to research the reaction mechanism of delphinidin/pelargonidin with free radicals including superoxide anion radicals (O2 - ∙) and hydroperoxide radicals (OOH∙). The geometric configuration, bond dissociation energy, PCM (polarizable continuum model)

Molecular Structure and Antioxidant Properties of Delphinidin

The Journal of Physical Chemistry A, 2008
Density functional theory calculations were performed to evaluate the antioxidant activity of delphinidin, taking into account its acid/base equilibrium. The conformational behavior of both the isolated and the aqueous solvation species (simulated with the polarizable continuum model) were analyzed at the B3LYP/6-31++G(d,p) level, considering the ...

Delphinidin Induces Autolysosome as well as Autophagosome Formation and Delphinidin‐Induced Autophagy Exerts a Cell Protective Role

Journal of Biochemical and Molecular Toxicology, 2012
ABSTRACTAnthocyanidins, which are polyphenols that are believed to be effective for preventing cancer, are composed of a basic structure of the plant pigment anthocyanin. In this study, we investigated the biological activity of anthocyanidins, including delphinidin, against HeLa cells.

The Multifunctional Benefits of Naturally Occurring Delphinidin and Its Glycosides

Journal of Agricultural and Food Chemistry, 2019
Delphinidin (Del) and its glycosides are water-soluble pigments, belonging to a subgroup of flavonoids. They are health-promoting candidates for pharmaceutical and nutraceutical uses, as indicated by exhibiting antioxidation, anti-inflammation, antimicroorganism, antidiabetes, antiobesity, cardiovascular protection, neuroprotection, and anticancer ...

Blockade of the Renin-Angiotensin System with Delphinidin, Cyanin, and Quercetin

Planta Medica, 2012
Overactivation of the renin-angiotensin system is one of the most important risk factors for the development of hypertension. The use of the crude extracts and/or active compounds, such as anthocyanins and quercetin, of herbal plants that have antihypertensive effects is beneficial for decreasing of blood pressure level.

Delphinidin- and cyanidin-chlorides, promotors of cell aggregation in vitro

Cell Biology International Reports, 1978
Delphinidin-chloride and Cyanidinchloride cause cells in cell culture to form aggregates instead of the usual monolayers, without impairing viability or proliferation. The process is reversible.

Delphinidin accumulation is associated with abnormal flower development in petunias

Phytochemistry, 2004
The relative floral anthocyanidin contents of 195 commercial petunias with floral colours other than white and yellow were determined using HPLC, and the presence of five anthocyanidins (cyanidin, peonidin, delphinidin, petunidin, and malvidin) was confirmed. Pelargonidin was not detected, and delphinidin was not a major component.

Delphinidin 3-xylosylrutinoside in petals of Linum grandiflorum

Phytochemistry, 1995
Abstract A new anthocyanidin triglycoside was isolated from the scarlet flowers of Linum grandiflorum cv Scarlet Flax as a major anthocyanin. The structure of this pigment was determined to be delphinidin 3-O[2-O(β- d -(xylopyranosyl)-6-O-α- l -rhamnopyranosyl)-β- d -glucopyranoside].

Activity of delphinidin on microvascular damage models in rodents

Phytotherapy Research, 1992
AbstractDelphinidin chloride (IdB 1056) was found to possess a significant activity by the intraperitoneal and oral routes in different experimental models of microvascular damage. It antagonized the increase in skin capillary permeability induced by histamine in rats and rabbits, by bradykinin and hyaluronidase in rats and by xylol in mice ...
