Phenolic acids can be found in mushroom basidiomycetes species. [45] For example, protocatechuic acid and pyrocatechol are found in Agaricus bisporus [46] as well as other phenylated substances like phenylacetic and phenylpyruvic acids. Other compounds like atromentin and thelephoric acid can also be isolated from fungi in the Agaricomycetes class.
It is difficult to evaluate the physiological effects of specific natural phenolic antioxidants, since such a large number of individual compounds may occur even in a single food and their fate in vivo cannot be measured. [1] [6] [8] Other more detailed chemical research has elucidated the difficulty of isolating individual phenolics.
Medicinal fungi are fungi that contain metabolites or can be induced to produce metabolites through biotechnology to develop prescription drugs.Compounds successfully developed into drugs or under research include those treating infection with amoeba, bacteria, fungus, virus, inhibitors of cholesterol and ergosterol synthesis, and psychotropics.
Natural phenols in horse grams (Macrotyloma uniflorum) are mostly phenolic acids, namely 3,4-dihydroxy benzoic, p-hydroxy benzoic, vanillic, caffeic, p-coumaric, ferulic, syringic, and sinapinic acids. [citation needed] Phenolic acids can be found in several mushroom-forming species of basidiomycetes. [2] It is also a part of the humic ...
[1] [2] [3] Polyphenols include phenolic acids, flavonoids, tannic acid, and ellagitannin, some of which have been used historically as dyes and for tanning garments. Curcumin , a bright yellow component of turmeric ( Curcuma longa ), is a well-studied polyphenol.
Phytochemicals are generally regarded as research compounds rather than essential nutrients because proof of their possible health effects has not been established yet. [4] [5] Phytochemicals under research can be classified into major categories, such as carotenoids [6] and polyphenols, which include phenolic acids, flavonoids, stilbenes or ...
According to Cancer Research UK, "there is currently no evidence that any type of mushroom or mushroom extract can prevent or cure cancer". [92] Nerium oleander (or oleander) – one of the most poisonous of commonly grown garden plants, is the basis of an extract which is promoted to treat cancer and other ailments. According to the American ...
UV visible spectrum of protocatechuic acid. Protocatechuic acid (PCA) is a dihydroxybenzoic acid, a type of phenolic acid. It is a major metabolite of antioxidant polyphenols found in green tea. It has mixed effects on normal and cancer cells in in vitro and in vivo studies. [4] It is produced commercially from vanillin. [5]
