“…The seeds are also edible and are normally roasted and consumed as pulses [ 8 ]. Commercially, tamarind seed is used as raw material for production of tamarind seed gum, for use in industries such as food [ 9 ] and medicine, as thickening and stabilizing agent [ 10 , 11 ]. Scientifically, the aqueous seed extracts of T. indica showed potent anti-diabetic and anti-hyperlipidemic activities in streptozotocin (STZ)-induced male rats [ 12 ].…”

BackgroundTamarindus indica L. (T. indica) or locally known as “asam jawa” belongs to the family Leguminosae. T. indica seeds as by-products from the fruits were previously reported to contain high polyphenolic content. However, identification of their bioactive polyphenols using recent technologies is less well researched but nonetheless important. Hence, it was the aim of this study to provide further information on the polyphenolic content and antioxidant activities as well as to identify and quantify its bioactive polyphenols.MethodsT. indica seeds were extracted with methanol and were then fractionated with different compositions of hexane, ethyl acetate and methanol. Polyphenolic contents were measured using Folin-Ciocalteu assay while antioxidant activities were measured using DPPH radical scavenging and ferric reducing (FRAP) activities. The cytotoxic activities of the crude extract and the active fraction were evaluated in HepG2 cells using MTT assay. The cells were then pre-treated with the IC20 concentrations and induced with H2O2 before measuring their cellular antioxidant activities including FRAP, DPPH, lipid peroxidation, ROS generation and antioxidant enzymes, SOD, GPx and CAT. Analyses of polyphenols in the crude extract and its active fraction were done using UHPLC and NMR.ResultsAmongst the 7 isolated fractions, fraction F3 showed the highest polyphenolic content and antioxidant activities. When HepG2 cells were treated with fraction F3 or the crude extract, the former demonstrated higher antioxidant activities. F3 also showed stronger inhibition of lipid peroxidation and ROS generation, and enhanced activities of SOD, GPx and CAT of HepG2 cells following H2O2-induced oxidative damage. UHPLC analyses revealed the presence of catechin, procyanidin B2, caffeic acid, ferulic acid, chloramphenicol, myricetin, morin, quercetin, apigenin and kaempferol, in the crude seed extract of T. indica. UHPLC and NMR analyses identified the presence of caffeic acid in fraction F3. Our studies were the first to report caffeic acid as the active polyphenol isolated from T. indica seeds which likely contributed to the potent antioxidant defense system of HepG2 cells.ConclusionResults from this study indicate that caffeic acid together with other polyphenols in T. indica seeds can enhance the antioxidant activities of treated HepG2 cells which can provide protection against oxidative damage.

“…The tamarind tree is widely used, including its bark, leaves, fruits, seeds and roots, as a pharmaceutical ingredient, food for human and animals, etc (Semenzato et al, 2014). The fruit is its most consumed portion, containing vitamins, tartaric and malic acids, sugars and due to the bittersweet taste, it is used as spice and as an ingredient in food products such as beverages, gravies, hot sauces, and worcestershire's sauce.…”

The tamarind tree (Tamarindus indica L.) is a common tree in tropical countries with a great exploitation potential due to its high nutritional value and important pharmaceutical characteristics, justifying its potential as a promising crop. The scarcity of scientific studies of the species, especially on propagation, hinders its availability and, consequently, the supply of the product in the market. The aim of this study was to verify the obtainment of nodal segments via sexual propagation and the in vitro establishment of sweet tamarind in MS culture medium (25, 50, 75 and 100% of salts) and with or without activated charcoal (2 g.L-1). The experiment was carried out in a completely randomized design in a 2 x 4 factorial scheme (presence and absence of activated carbon x salt concentrations), with 25 replicates, each replicate consisting of a test tube with an inoculated explant. According to the results, it is possible to conclude that from seedlings with 45 days after sowing, nodal segments of sweet tamarind are obtained for in vitro establishment. As a precursor of protocol for in vitro formation of healthy seedlings is indicated the use of MS culture medium with 75 % of the salts and added with 2 gL-1 of activated charcoal to reduce the contamination index.

Name of cellulose is referred to a type of natural carbohydrate with many hydroxyl groups and high water absorption capacity. Cellulose is the most abundant natural polymer, found as the main constituent of plants (plant cellulose). Some bacteria such as Acetobacter xylinum are also able to synthesize bacterial cellulose. Cellulose-based hydrogels are superabsorbent materials, which make 3D networks. Chemical bonds or other cohesive forces such as hydrogen bonding or ionic interactions connect the cellulose chains together. Hydrogels can swell and absorb water and other aqueous fluids in their 3D networks, but they are insoluble in them. Nowadays, an increasing demand emerges for biodegradable materials and products made from renewable resources such as cellulose. The excellent biocompatibility of cellulose has prompted the large use of cellulose-based personal care products. Cellulose hydrogel is used for these products as the thickener and stabilizing agents or as moisturizing agent to improve the skin feel of the product. Hygienic cellulosic absorbent products such as diapers, panty liners, tampons, paper towels, and tissue papers are used as personal care products. These products are available in different absorbency ratings from junior to ultra-absorbency. Using cellulose-based hydrogel, superabsorbent products are made. In this review, applications of cellulose-based hydrogels in personal care products were reviewed.
