The biological activity of the wine anthocyanins delphinidin and petunidin is mediated through Msn2 and Msn4 in Saccharomyces cerevisiae [PDF]

FEMS Yeast Research, 2010
Polyphenols are considered to be responsible for some of the health benefits derived from the consumption of red wine. These protective effects might probably be explained in the context of the xenohormesis theory that considers plant metabolites as interspecific chemical signals.

Targeting NOX 4 by petunidin improves anoxia/reoxygenation-induced myocardium injury

European Journal of Pharmacology, 2020
Oxidative stress is the key factor of myocardial ischemia-reperfusion injury (MIRI). Anthocyanins are considered to be effective anti-oxidants. In this study, we observed the anti-MIRI effect of petunidin, one member of anthocyanins, and further explored its mechanism.

A computational exploration into the structure, antioxidant capacity, toxicity and drug-like activity of the anthocyanidin “Petunidin”

Heliyon, 2019
A computational investigation on the structure and antioxidant property of a natural food colorant Petunidin (PT) was performed under DFT/B3LYP/6-31+ G (d, p). PT has a drug score of +0.804 which indicates its drug-like nature. The antioxidant property of PT was well explained by HAT mechanism and it has been found that the electron releasing ...

A new petunidin tetraglycoside and tulipanin fromOphiopogon seeds

Botanical Magazine, 1980
Blue seed-coats ofOphiopogon jaburan have been found to contain two kinds of anthocyanins. By means of paper chromatographic and spectral analyses, one present as a minor component was determined to be delphinidin 3-rutinoside, tulipanin, and the major component, a new anthocyanin, was identified as petunidin 3-O-β-(2G-glucosylrutinoside)-5′-glucoside,

Effects of heat, ultrasound, and microwave processing on the stability and antioxidant activity of delphinidin and petunidin

Journal of Food Biochemistry, 2019
The effects of conventional heating, ultrasonic, and microwave treatments on the stability and antioxidant activities of anthocyanidin standards (delphinidin and petunidin) were studied. The antioxidant activities of delphinidin and petunidin significantly decreased during the treatments, which suggested that the antioxidant activities of the ...

Petunidin, a B-ring 5′-O-Methylated Derivative of Delphinidin, Stimulates Osteoblastogenesis and Reduces sRANKL-Induced Bone Loss [PDF]

International Journal of Molecular Sciences, 2019
Several lines of evidence suggest that oxidative stress is one of the key pathogenic mechanisms of osteoporosis. We aimed to elucidate the bone protective effects of petunidin, one of the most common anthocyanidins, considering its potent antioxidative activity. Petunidin (>5 μg/mL) significantly inhibited osteoclastogenesis and downregulated c-fos,

Synergistic antioxidant effects of petunidin and lycopene in H9c2 cells submitted to hydrogen peroxide: Role of Akt/Nrf2 pathway

Journal of Food Science, 2020
Abstract Phenolics and carotenoids coexist in fruits and vegetables and could possess interaction effects after consumption. The present study aims to elucidate the possible mechanisms of the antioxidant interactions between anthocyanins and carotenoids using petunidin and lycopene as ...
