“…3). This content was lower than that observed for O. ficus indica peel polysaccharides (65%) (Forni et al, 1994), and higher than that found in dietary fibre containing material from olive mill wastewater (3.3 g /100 g) (Galanakis et al, 2010).…”

A b s t r a c t. Opuntia stricta Haw. is considered as one of the most common cactus plant growing in Tunisia. Extracting valuable compounds from its fruit peel, considered as by-product, is drawing more and more attention, making it on the verge of commercialization. Water-soluble polysaccharides were extracted from Opuntia stricta Haw. peels, and their chemical composition assessed using thin layer chromatography. The antioxidant activities of the extracted polysaccharides were assessed using 2,2-diphenyl-1-picrylhydrazyl free radical scavenging activity, total antioxidant activity and reducing power capacity. The extraction yield of water-soluble polysaccharides was 7.53±0.86%. The chemical composition revealed the presence of rhamnose, arabinose, glucose, mannose, galactose and galacturonic acid. The infra-red spectroscopic analysis showed a similar structure to that of Opuntia ficus-indica polysaccharide peels. Additionally, the extracted polysaccharides exhibited high antioxidant activities. In fact, the free radical scavenging activity (half inhibition concentration = 6.5 mg ml -1 with 94.9% inhibition at 50 mg ml -1

“…Parikh and Jones (1965) said that the mucilage of the Opuntia fulgida consisted of a main structure of galactose joined by a glicosidic linkage β (1→3) with ramifications in the C-6 that contains D-galacturonic acid, D-galactose, D-xylose, L-rhamnose, and units of L-arabinose. Forni, Penci and Polesello (1994). However, some authors (ANDERSON; SANDS; STURGIS, 1925;KLAAS, 1929;PARIKH;JONES, 1965;AMIM et al, 1970) identified rhamnose in other varieties of Opuntia.…”

“…(Silva et al 2005), and also from increased levels of vitamin C (Tetera 2006). Quinces are important also for the canning industry, especially due to their high contents of pectins (Kyzlink 1990;Forni et al 1994). From the sensory point of view, an intensive quince-like smell represents an important qualitative trait (Lutz & Winterhalter 1992); this is due to an increased content of aromatic substances (Escher & Niclass 1991).…”

Rop O., Balík J., Řezníček V., Juríková T., Škardová P., Salaš P., Sochor J., Mlček J., Kramářová D. (2011): Chemical characteristics of fruits of some selected quince (Cydonia oblonga Mill.) cultivars. Czech J. Food Sci., 29: 65-73.The basic chemical characteristics of 22 quince (Cydonia oblonga Mill.) genotypes and cultivars were determined: dry matter content, soluble solid content, the contents of organic acids, pectins, and mineral elements (nitrogen, phosphorus, potassium, calcium, and sodium). Quince fruits were harvested in the course of October and thereafter analysed at the stage of consumption ripeness after storage at the temperature of +2°C and a relative air humidity of 85%. The contents of pectins in fruits were high -the cultivar Hruškovitá contained 3.51 ± 0.19 g/100 g FW. The contents of vitamin C were also high, the cultivar Muškatová containing as much as 79.31 ± 2.01 g/100 g FW. The affinity of chemical properties of the individual cultivars was expressed by means of cluster analysis and it was found out that there were no marked differences between pear-shaped (Cydonia oblonga subsp. pyriformis) and apple-shaped (Cydonia oblonga subsp. maliformis) forms of fruit.
