Acylated Peonidin 3-Rutinoside-5-glucosides from Commercial Petunia Cultivars with Pink Flowers

HETEROCYCLES, 2004
Two new acylated peonidin glycosides and three known acylated or non-acylated peonidin glycosides were identified in the flowers of 17 commercial pink petunias: peonidin 3-O-[6-O-(4-O-(4-O-(6-O-(trans-caffeoyl)-β-D-glucopyranosyl)-trans-p-coumaroyl)-α-L-rhamnopyranosyl)-β-D-glucopyranoside]-5-O-[β-D-glucopyranoside], peonidin 3-O-[6-O-(4-O-(4-O-(β-D ...

An acylated peonidin glycoside in the violet-blue flowers of Pharbitis nil

Phytochemistry, 1991
Abstract A new acylated anthocyanin was isolated from the violet-blue flowers of Pharbitis nil as a major anthocyanin. The structure of this pigment was determined to be peonidin 3[6″-(4-glucosyl- trans -caffeyl)sophoroside]-5-glucoside. Peonidin 3-sophoroside-5-glucoside was also detected as a minor pigment.

Peonidin 3-Glucoside Inhibits Lung Cancer Metastasis by Downregulation of Proteinases Activities and MAPK Pathway

Nutrition and Cancer, 2010
Anthocyanins, present in various vegetables and fruits as a nature colorant, have broad activities including anticarcinogenesis and antimutagenesis, which are generally attributed to their antioxidant activities. However, limited studies have been available concerning the inhibitory effect of peonidin 3-glucoside (P3G) for cancer metastasis.

Triacylated peonidin 3-sophoroside-5-glucosides from the purple flowers of Moricandia ramburii Webb.

Phytochemistry, 2012
Triacylated peonidin 3-sophoroside-5-glucosides were isolated from the purple flowers of Moricandia ramburii Webb. (Family: Brassicaceae), and determined to be peonidin 3-O-[2-O-(2-O-(trans-feruloyl)-glucosyl)-6-O-(trans-p-coumaroyl)-glucoside]-5-O-[6-O-(malonyl)-glucoside] (1), peonidin 3-O-[2-O-(2-O-(trans-feruloyl)-glucosyl)-6-O-(cis-p-coumaroyl ...

A non toxic natural food colorant and antioxidant ‘Peonidin’ as a pH indicator: A TDDFT analysis

Computational Biology and Chemistry, 2018
A computational inestigation on the difference in colors of two plants 'Peony' and 'Morning glory' by the same pigment 'Peonidin' has been performed by means of absorption characteristics. Peonidin imparts purple color to the flowers in Peony and blue to that in Morning glory.

Structure Elucidation of Peonidin 3,7-O-β-Diglucoside Isolated from Garnacha Tintorera (Vitis vinifera L.) Grapes

Journal of Agricultural and Food Chemistry, 2010
Red wines made from Garnacha Tintorera grapes (also known as Alicante Bouschet and one of the few so-called teinturier Vitis vinifera grape cultivars, because its berry flesh is also red-colored) are usually blended with other red wines as a natural way for enhancing the color intensity of red wines.

Peonidin‐3‐O‐glucoside and cyanidin increase osteoblast differentiation and reduce RANKL‐induced bone resorption in transgenic medaka

Phytotherapy Research, 2021
Experimental and clinical studies suggest a positive impact of anthocyanins on bone health; however, the mechanisms of anthocyanins altering the differentiation and function of osteoblasts and osteoclasts are not fully understood. This work demonstrates that dietary anthocyanins and resveratrol increased proliferation of cultured human hFOB 1.19 ...

The natural food colorant Peonidin from cranberries as a potential radical scavenger – A DFT based mechanistic analysis

Food Chemistry, 2018
A theoretical evaluation of the antioxidant property of a natural food colorant Peonidin has been performed. The most suitable mechanism for explaining the radical scavenging capacity of Peonidin is the Hydrogen Atom Transfer and the most active site for radical formation is position 3 and is confirmed through Mulliken charge analysis, pKa value ...

The Anthocyanidin Peonidin Interferes with an Early Step in the Fibrillation Pathway of α-Synuclein and Modulates It toward Amorphous Aggregates

ACS Chemical Neuroscience, 2023
Parkinson's disease (PD) is characterized by progressive degeneration of the dopaminergic neurons in the brain, accompanied by the accumulation of proteinaceous inclusions, Lewy bodies (LB), mainly comprised of alpha synuclein (α-syn) aggregates. The heterogeneity and the transient nature of the intermediate species formed in the α-syn fibrillation ...

Combination of the anthocyanidins malvidin and peonidin attenuates lipopolysaccharide-mediated inflammatory gene expression in primary human adipocytes

Nutrition Research, 2016
We recently demonstrated that California table grapes and a methanol-extractable, polyphenol-rich fraction decreased adiposity, insulin resistance, or markers of inflammation in high-fat fed mice. Malvidin and peonidin glycosides were the 2 most abundant anthocyanins in the polyphenol-rich fraction.
