Natural Materials: Sources, Properties, and Uses
It is used as a binding material in mortars for stoneware. It is used for plastering walls, ceilings, etc. It is employed for white washing and as a base coat for distempers. It is used for knotting of timber work before painting. It is used in the manufacture of paints. It is used for stabilizing the soils. For centuries, the plant has been utilized as a part of customary practices in South America particularly in Peru. Due to its anti-inflammatory and radical-scavenging activities, the plant has been used to treat rheumatic diseases and cancer [ ].
Decoctions prepared from the bark of U. The bark decoctions have strong ability to decrease the free radicals diphenylpicrylhydrazyl, hydrogen peroxide, and hypochlorous acid [ ]. Leea indica belongs to the family Vitaceae and has been traditionally used as natural folk medicine in Malaysia. In the leaves of L. Among these, total phenolic compounds possess the antioxidant activity [ ]. Polyalthia cerasoides belongs to the family Annonaceae and is a medicinal plant used in Thai native medicine.
The roots of P. The extract has the highest phenolic compound and high reactive oxygen species-scavenging activity [ , ]. Marine ecosystem has been reported as a potential source of biodiversity and chemical activities. The organisms living in marine environment are gaining the attention of industries such as pharmaceuticals, nutraceuticals, and cosmetics because of possessing various interesting and useful chemical compounds [ ]. Marine biotechnologists are trying to produce the tool for the utilization of marine biodiversity for the production of cheap source of pharmaceutical products and functional foods [ ].
Seaweeds and sponges are considered as the richest source of bioactive compounds having the antimicrobial and antioxidant activities [ ]. Seaweeds and sponges with their associated bacteria have been found to possess various health-promoting and disease prevention effects due to their phenolic compounds, polysaccharides, and useful organic acids [ ].
These are supposed to be the most protective group of foods against environmental pollutants and radiation [ ]. Among various other useful compounds, the marine organisms also contain polyphenolic compounds that are responsible for antioxidant activity including flavonoids, benzoic acid, cinnamic acid, gallic acid, quercy, and phlorotannins [ ].
Nonanimal sulfated polysaccharides are reported to have antioxidant activities [ ], which can be obtained from marine algae and other marine organisms from the phaeophyta group [ ]. A large number of different species of algae and microalgae have been studied for the use of their bioactive contents as functional food components. Algae comprised of a huge and complex group of photosynthetic organisms with simple reproductive organs, which can be multicellular, known as macroalgae and unicellular called as microalgae.
Algae grow in extremes of environmental conditions such as light, temperature, and salinity, which results in the production of a large number of reactive oxygen species ROS. To cope with these ROS, algae produce various secondary metabolites with many antioxidant activities such as phycobilins, polyphenols, carotenoids, and vitamins [ ]. People living in coastal areas use many types of seaweed, both as fresh and dry forms, as a natural source of food, and from the research, it is known that these seaweeds contain a large amount of proteins, minerals, and vitamins.
Although the composition of these seaweeds varies according to their species, geographical distribution, temperature, and seasonal variation, the overall nutritional value remains the same. Many compounds from marine algae possess anticancer activity, and recently, seaweeds have gained attention as a rich source of antioxidants [ ]. Many of the secondary metabolites produced by marine organisms reflect the presence of chloride and bromide ions in seawater.
Marine halogenated compounds assemble a large number of other useful compounds such as indoles, peptides, terpenes, phenols, acetogenins, and volatile halogenated hydrocarbons. This protective effect suggests the presence of antioxidant compounds that show their antioxidant activity as free radical scavengers, hydrogen-donating compounds, single oxygen quenchers, and metal ion chelators. Many biological compounds have previously isolated from some other marine organisms such as fish, crustaceans, and their byproducts [ ]. Seaweeds also create a suitable environment to a large number of bacteria that live on their surface having much more diversity of microorganisms as compared to other multicellular organisms [ ].
These associated microorganisms have a protective effect on the seaweeds from pathogen, and they produce a large number of bioactive compounds of biomedical importance [ ]. Exopolysaccharides produced by these bacterial species are used as an ingredient in food, petroleum, and pharmaceutical industries and emulsification of crude oil, vegetables, mineral oils, and bioremediation agents in environment management systems [ ].
Fish protein hydrolysate FPH , which is prepared from various marine organisms such as mackerel, tuna, Alaska Pollock, and yellowfin sole, has also been reported to have antioxidant activity [ , , ]. Many types of peptides are obtained from fish muscle, bone, skin, and other tissues. All of these amino acids can scavenge-free radicals, but the most powerful scavenging activity attributes to those who can easily donate hydrogen atoms.
These amino acids are cystine and methionine, which have nucleophilic sulfur-containing side chains or tryptophan, tyrosine, and phenylalanine, which have aromatic side chains. Peptide size and amino acid composition are important for the FPH because it determines its antioxidant nature [ ]. Algal antioxidants are also used in the cosmeceutical industries as antiaging agents [ ].
A carotenoid pigment known as astaxanthin, found in microalga Haematococcus pluvialis , is reported to have anti-inflammatory, immunomodulatory, and antioxidant activities [ ]. An increasing interest has been observed from the past decade in exploring the natural ingredients to be used in the food and food products.
The researchers from all over the world are focusing on the alternate sources other than the synthetic one, which will be more safe and convenient as dietary component. Moreover, the synthetic antioxidants and preservatives in the food may lead to lipid peroxidation and deterioration of food flavor and quality. The use of natural herbs, spices, and plant ingredients is in practice from the ancient times and still practiced in the traditional food preparation as preservative, aroma, and flavor.
This chapter is an effort to overview the potentials of various natural sources having reasonable antioxidant potential. The literature reports compiled here will be beneficial to identify the significance of various natural sources based on their antioxidant capacity, active ingredients, and geographic availability.

Downloaded: Abstract Antioxidants are the defense system of the body against the damage of reactive oxygen species, which is normally produced during the various physiological processes in the body. Keywords antioxidants vegetables fruits plants herbs. Introduction The formations of oxygen reactive forms as a result of rigorous oxidative processes taking place in human organism are the potent precursors of systemic cells and tissues damage.
Natural antioxidants The nature is always a significant and rich source of countless ingredients that can be served as health-promoting agents. Types of antioxidants from fruits and vegetables Polyphenols, present in fruits and vegetables, is a group of several low- and high-molecular-weight compounds having antioxidant properties that prevent lipid oxidation [ 17 ].
