“…Free radicals are also involved in the defense system; phagocytes release them to destroy pathogenic microbes [33, 34]. They also participate in cellular signaling systems [29, 31, 32, 35] and seem to play a role in the regulation of insulin receptor kinase activity [33] and in the apoptosis of defective cells [36, 37]. In summary, free radicals at low/moderate levels are essential for optimal human health.…”

: Oxidative stress has been proven to be related to the onset of a large number of health disorders. This chemical stress is triggered by an excess of free radicals, which are generated in cells because of a wide variety of exogenous and endogenous processes. Therefore, finding strategies for efficiently detoxifying free radicals has become a subject of a great interest, from both an academic and practical points of view. Melatonin is a ubiquitous and versatile molecule that exhibits most of the desirable characteristics of a good antioxidant. The amount of data gathered so far regarding the protective action of melatonin against oxidative stress is overwhelming. However, rather little is known concerning the chemical mechanisms involved in this activity. This review summarizes the current progress in understanding the physicochemical insights related to the free radical–scavenging activity of melatonin. Thus far, there is a general agreement that electron transfer and hydrogen transfer are the main mechanisms involved in the reactions of melatonin with free radicals. However, the relative importance of other mechanisms is also analyzed. The chemical nature of the reacting free radical also has an influence on the relative importance of the different mechanisms of these reactions. Therefore, this point has also been discussed in detail in the current review. Based on the available data, it is concluded that melatonin efficiently protects against oxidative stress by a variety of mechanisms. Moreover, it is proposed that even though it has been referred to as the chemical expression of darkness, perhaps it could also be referred to as the chemical light of health.

A variety of natural vinegar products are found in civilizations around the world. A review of research on these fermented products indicates numerous reports of health benefits derived by consumption of vinegar components. Therapeutic effects of vinegar arising from consuming the inherent bioactive components including acetic acid, gallic acid, catechin, ephicatechin, chlorogenic acid, caffeic acid, p-coumaric acid, and ferulic acid cause antioxidative, antidiabetic, antimicrobial, antitumor, antiobesity, antihypertensive, and cholesterol-lowering responses. The aims of this article are to discuss vinegar history, production, varieties, acetic acid bacteria, and functional properties of vinegars.

“…4 Though there are no direct evidences to the said anti-microbial and anti-bacterial properties of the sakuraleaves, few researches on the antioxidant activity of Prunus species are available. [5][6][7][8] The reason behind the use of the leaves of the sakura tree, in particular the double cherry blossom leaves, for edible use is thought to lie in its numerous metabolites, including the presence of isoroflavone purnetin, its glycoside plunnetrin, flavonoid isoquercitrin, and merylose side of coumarin glycoside; and there are some related literature available from flowers and leaves. 7,9,10 These compounds have been reported to have sedation, antitussive, expectorant, insomnia, mental stability, and relaxing effects.…”

The present research examines the possibility of finding bio-molecular compounds from the double cherry blossom (termed as 'Gosen-Sakura' of Gosen-city, Niigata-prefecture, Japan) leaves, which have been long used in the preparation of the traditional Japanese sweet (wagashi)-'sakura-mochi'. Based on its indicated anti-microbial properties historically, our study provides a new low temperature vacuum extraction method for extracting 'near natural form of water soluble leaf (cell) extracts from the Gosen-Sakura, and demonstrates the presence of some 'novel' compound(s) with anti-tumor cell lines proliferation inhibitory affects through the MTT assay. To our knowledge, no reports exist on the sakura tree 'leaf (cell) extracts' inhibiting tumor cell line growth. We further examined and compared the effects of known compounds with anti-tumor activity, coumarin and benzyl alcohol with Gosen-Sakura leaf extract; results lead us to hypothesize that the Gosen-Sakura leaf extract contains substance(s) other than the above two known compounds, with antitumor effect. Additionally, we speculate on the underlying mechanism of action of the Gosen-Sakura leaf extract by targeting cell division at the point of DNA synthesis and causing apoptosis. In conclusion, we present scientific evidence on the presence of certain 'novel' biomolecule(s), with anti-tumor activity, in the Gosen-Sakura leaf which has been long used in Japanese sweetthe 'sakura-mochi'.
