1.note:
The human life span has increased from about 55 years to 75 years in last few decades. This has been possible due to the increasing control over life threatening diseases due to parallel developments in chemical sciences, particularly in the areas of synthetic & medicinal chemistry and in biological sciences. This special issue of Biochimie on Advances in Biomolecular and Medicinal Chemistrybased on selected lectures presented at the ISCBC-2009 held at the University of Delhi, Delhi is important because of the timeliness of the discussions on research in the cutting edge areas of chemical and biological sciences. One of the problems we are facing at the moment is the maintenance of the quality of the life of growing old-aged population. Both, chemists and biologists are working together to find out solutions to contribute towards a good quality life to old-aged population and also to maximize the life span of human being, per se from 100 years to 125 years. One of the theories to explain the maximum life span and death is the homeostatic theory, which postulates that the oxidative defense mechanism of the body deteriorates with aging because of a genetically programmed reduction in the synthesis of antioxidants in cells or reduced absorption of antioxidant vitamins from the diet. 2.letter
To the Editor: I read with much interest the article by Moreno-Macias and Romieu. The authors discussed the importance of antioxidant supplements and nutrients. Over the last decade, my colleagues and I have performed experimental laboratory studies on various potential herbs and their extracts. Many of the oxidative stress disorders in experimental animals were shown to have fewer complications or even the damages were reverted once treated with herbal supplements. 我兴致勃勃地读完了Moreno-Macias Romieu的文章,文章里作者讨论了抗氧化补充剂和抗氧化营养剂的重要性。而在过去的十年里,我和我的同事们对各种潜在的草药及其提取物进行了实验研究,研究表明许多具有氧化应激障碍的实验动物,一旦食用了此类草药或其提取物,它们因氧化应激障碍而产生的并发症和对身体损害都会减少。
3.full paper: Morus is a genus of 10-16 species of deciduous trees native to warm, temperate, and subtropical
regions of Asia, Africa, North America, and southern Europe (Watson & Dallwitz, 2007. Morus nigra L. is a rustic plant growing wildly, cultivated in gardens or commonly used in sericulture. In Europe, it is appreciated more for their fruits than for the foliage (Gerasopoulos & Stravroulakis, 1997. In Italy, the berries of M. nigra and M. alba are consumed as a fresh fruit or in the form of various confectionary products such as jam, marmalade, frozen desserts, pulp, juice, paste, ice cream. Previous phytochemical studies on the fruits Morus species showed the presence of fats and fatty acids, vitamin C, minerals, phenolics, and flavonoids (Ercisli & Orhan, 2007 and, in the case of black mulberry fruits, some organic acids (Koyuncu, 2004 and anthocyanins (Dugo, Mondello, Errante, Zappia, & Dugo, 2001. M. nigra berries showed also a high antioxidant activity in the b-carotene bleaching method and against liposome oxidation as reported by Hassimotto, Genovese, and Lajolo (2005. Compared to other berries, the bioactive compounds of mulberry fruits have not been extensively studied.
Anthocyanins are a group of naturally occurring flavonoid polyphenols responsible for the colour of many plants (Tanaka, Sasaki, & Ohmiya, 2008, and are especially abundant in berries (Dugo et al., 2001. Fruit extracts containing high levels of anthocyanins, such as those from strawberry and plum, demonstrated high radical scavenging activity by the DPPH method (Espin, Soler- Rivas, Wichers & García-Viguera, 2000. High antioxidant activity was also observed on fruits of Rubus and Prunus species (Jakobek, Seruga, Novak, & Medvidovic-Kosanovic, 2009. Direct correlation between antioxidant activity and anthocyanin content was demonstrated for berries (Kalt, Forney, Martin, & Prior, 1999.
M. nigra L. fresh fruit is hardly commercialised. Because of its fragile structure and low stability in storage, it is usually processed as jelly or juice. Another possibility is commercializing fermented fruit. It has been widely reported that cardioprotective effect can be achieved by moderate consumption of some alcoholic fermented beverages (such as wine or beer as consequence of their content of phenolic compounds (Gorinstein, Caspi, Libman, & Trakhtenberg, 2000 but also ethanol. Since the antioxidant activity of phenolic phytochemicals is enhanced in presence of alcohol, it could be assumed that fermented alcoholic fruits have higher antioxidant activity than raw fruits (Chanjirakul, Wang, Wang, & Siriphanich, 2007. However there are few authors who have studied the antioxidant activity of mulberries (Chon et al., 2009; Du, Zheng, & Xu, 2008; Zhang, Han, He, & Duan, 2008. Furthermore studies on the characterization and quantification of mulberry anthocyanins are very limited (Lee et al., 2004; Pawlowska, Oleszek, & Braca, 2008 and none about the effect of fermentation in their anthocyanin content and antioxidant activity.
This article is mainly concerned with the method of extracting flavonoids from mulberry fruits and the determination of the content of flavonoids in the extracts. In parallel, the scavenging effects of mulberry extracts on free radicals were measured using the DPPH method. The effect of fermentation on antioxidant potential of Mulberries flavonoids was studied. 桑属是植物的一个属,包括有10-16个种的落叶乔木,原产于亚洲、非洲、北美洲和南欧的温带及亚热带地区。黑桑(Morus nigra L)生长或被种植于园林中,并通常用于养蚕业。在欧洲,人们更倾向于利用桑树的果实而不是它们的叶子。
4.review: Fruits and vegetables contain many antioxidant compounds, including phenolic compounds, carotenoids, anthocyanins and tocopherols (Naczk & Shahidi, 2006. Most antioxidants are polyphenolic compounds, which act as reducing agents (free radical terminators, metal chelators, singlet oxygen quenchers (Mathew & Abraham, 2006 and hydrogen donors (Miller & Rice-Evans, 1997. Fermentation is an ancient technology used to enhance the shelf-life and nutritional and organoleptic qualities of food (Frias, Miranda, Doblado, & Vidal-Valverde, 2005. Many biochemical changes occur during fermentation, leading to an altered ratio of nutritive and anti-nutritive components and, consequently, affects the products
properties, such as bioactivity and digestibility (Zhang et al., 2012. Recently, this bioprocess has been applied to the production and extraction of bioactive compounds in the food, chemical and pharmaceutical industries (Martins et al., 2011; Torino et al., 2013. For example, fermentation has been applied to increase the content of bioactive phenolic compounds in legumes, thus enhancing their antioxidant activity (Lee, Hung, & Chou, 2008; Torino et al., 2013. Torino et al. (2013 reported that the bioconversion of the conjugated forms of phenolic compounds into their free forms during fermentation improves their health-linked functionality. Lactic acid bacteria have been employed in foods to produce angiotensin converting enzyme (ACE-inhibitory peptides and c-aminobutyric acid, both of which are useful in the prevention and treatment of hypertension (Kono & Himeno, 2000; Torino et al., 2013. In general, antioxidants prevent the auto-oxidation of food components and neutralise the plethora of free radicals that are generated within the human body (He et al., 2012. Many ligninolytic and carbohydrate-metabolising enzymes hydrolyse phenolic glycosides and release free aglycones, which have the potential for high antioxidative activity and are thus very useful for applications in the food and beverage industries (Vattem & Shetty, 2003. For the reasons discussed above, the fermentation of food materials is a useful tool to improve the antioxidative activity of food products. This study provides an overview of the factors during fermentation that influence antioxidative activity and the mechanisms that augment antioxidative activities in fermented plant-based foods.
