Juglone, also called 5-hydroxy-1,4-naphthalenedione (IUPAC) is a phenolic organic compound with the molecular formula C 10 H 6 O 3. In the food industry, juglone is also known as C.I. Natural Brown 7 and C.I. 75500. It is insoluble in benzene but soluble in dioxane, from which it crystallizes as yellow needles.

Juglone is a hydroxy-1,4-naphthoquinone that is 1,4-naphthoquinone in which the hydrogen at position 5 has been replaced by a hydroxy group. A plant-derived 1,4-naphthoquinone with confirmed antibacterial and antitumor activities. It has a role as a herbicide, a reactive oxygen species generator and a geroprotector.

Es la especie del género más difundida en Europa, extendiéndose por todo el suroeste y centro de Asia, hasta el Himalaya y sudoeste de China. Es cultivado por la madera, las hojas aromáticas y el fruto comestible, la nuez. Además tiene un uso ornamental.

Jun 6, 2022 · Juglone (5-hydroxy-1,4-naphthalenedione) is a naturally occurring naphthoquinone derivative that has been known for more than a century. In 1905, French scientists M. Brissemoret and R. Combes reported that juglone exists in the green portions of walnut trees (leaves, stems, and husks). Their report cites articles from 1884.

Juglone (5-hydroxyl-1,4-naphthoquinone) is a phenolic compound found in walnuts. Because of the antioxidant capacities of phenolic compounds, juglone may serve to combat oxidative stress, thereby protecting against the development of various diseases and aging processes.

Jan 10, 2025 · The commonly held belief is that walnuts and other trees in the genus Juglans produce a chemical called juglone and it is this chemical that affects other plants. It turns out that walnuts don’t produce juglone, or at least not very much of it. Instead they produce a chemical called hydrojuglone.

In this work, we make a profound review of juglone synthesis methodology, the biological actions of juglone, and mainly the synthesis and pharmacological actions of juglone derivatives.

Se revisó el estado actual del conocimiento sobre el uso potencial de juglona (5-hidroxi-1,4-naftoquinona), el aleloquímico producido por los nogales negros (Juglans nigra), que ha sido investigado para aplicaciones en una variedad de diferentes fines agrícolas.

Juglone represents the simplest 1, 4-napthoquinone derivative produced naturally in plants. The phytotoxin juglone is a naphthoquinone produced by the black walnut tree (Juglans nigra) and exhibits high reactivity with oxygen and reactive oxygen species (ROS).

Jan 1, 2012 · Juglone (5-hydroxy-1,4-naphthoquinone) is known primarily for its allelopathic effect against certain plants and toxicity towards marine organisms. It has a wide variety of potential uses...
