“…Freshly harvested cactus pear cladodes are regarded as vegetables; they present a high content of water and a minor proportion of dietary fiber, lipids, proteins and calcium. Other constituents are antioxidants, such as ascorbic acid, phenolic compounds, β-carotene, lutein and xanthophylls [13][14][15][16][17]. This part of the plant is known for its medicinal properties, such as an auxiliary treatment for obesity, and gastrointestinal or cardiovascular disorders.…”

ABSTRACT. In this study, young cladodes corresponding to two (thorn-less and thorn-containing) varieties of cactus pear (Opuntia ficus-indica) from four different areas of Tigray region, Ethiopia, were investigated for their phenolic contents and antioxidant activities. Quantitative estimation of total phenolic contents and antioxidant activities in the cladodes was carried out using spectrophotometric methods. A 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging assay was used for the determination of the antioxidant activities, while Folin-Ciocalteau reagent, aluminum chloride and protein (albumin) precipitation methods were used for the determination of total polyphenol, flavonoid and tannin contents, respectively. The cladodes were found to be rich in polyphenols, with values in the range 18.071.4 mg gallic acid equivalent (GAE)/g of dry weight (DW). The predominant part of the polyphenols is represented by tannins, 9.0041.2 mg GAE/g of DW, followed by flavonoids, 6.4025.0 mg catchin equivalent (CE)/g of DW. The cladodes showed strong antioxidant activities, 59.385.8% inhibition compared to ascorbic acid. Application of paired t-test on the overall mean total polyphenol contents of samples collected from the different areas revealed the presence of significant variation between the thorn-less (31.6 GAE/g of DW) and thorn-containing (47.7 GAE/g of DW) varieties. One-way ANOVA also revealed that there are significant variations among samples from the same variety but collected from different areas.

“…Cactus pear is known as a multi-purpose plant since it can be used for human food (fruits and vegetables), fodder, medicinal and ornamental plants (Casas and Barbera, 2002;Rodriguez-Felix, 2002). This plant is recognized as a good indicator of noxious (Nobel, 1994).…”

In Vitro Propagation of Three Moroccan Prickly Pear Cactus Opuntia and Plant Establishment in Soil

et al. 2013

Opuntia is one of the most widespread cacti, primarily due to their edible fruit and vegetable mass used as feed. The high demand for young plants of Opuntia made it necessary to find a rapid method of multiplication of the cactus, the safest method consisting in vitro micropropagation of species belonging to this genus. With aim of large production of plant material, a propagation system of three important prickly pear cactus cultivar (Opuntia ficus-indica) in Morocco was developed. Segments of healthy young cladode (containing one areole) were cultivated in Murashige and Skoog medium (MS) containing adenine sulfate (40 mg/1), monosodium phosphate (50 mg/l), sucrose (50 g/l), phytagel (0.3%) and benzyladenine (BA) at 22.2 μM, to start the process of micropropagation. In vitro-developed shoots from areoles were used as secondary explants to induce shoot development in the MS medium with 5 mg/l of BA. All of the three studied cultivars showed an important multiplication rate in this medium. 'Sidi Ifni M' ('Moussa') cultivar shows the greatest number of shoots followed by 'Sidi Ifni A' (' Aissa') and 'Delahia' 17.26, 14.12 and 12.13 respectively. Rooting of in vitrogenerated shoots was achieved most efficiently on half-strength MS basal medium supplemented with 0.5 mg/l of indole-3-butyric acid (IBA) or IAA. Rooting frequencies were in the range from 95 to 100% and the highest mean number of root (19.1) was obtained with IBA for 'Delahia' cultivar. All micropropagated plants were transferred to greenhouse and all of them survived acclimatization process and showed good overall growth.

“…The international quality standard nopal, CODEX STAN 185-1993, provides that the tender cladodes can be marketed when they present from 9 cm to 30 cm in length (FAO-WHO, 1993). Cladodes 20 cm in length and weight of 90-100 g, are marketed as whole stalk (Cantwell, 1999); while smaller cladodes (12 cm) or longer (about 30 cm) are used for the production of fresh-cut produce (Rodriguez, 2002).…”

“…The enzymatic browning is one of the main problems limiting the marketing of nopal, both in their whole form as fresh-cut (Rodriguez, 2002). This deterioration is of great importance for its visual impact affecting the organoleptic acceptance and merchantable quality and reduce the nutritional value of fruits and vegetables (Artes et al, 2007).…”

En este trabajo se evaluó la actividad de polifenoloxidasa (PPO), el contenido de compuestos fenólicos totales y de ácido ascórbico y el grado de oscurecimiento durante el desarrollo de nopal verdura de variedades comerciales. Se cosecharon cladodios tiernos de 9 a 30 cm de longitud de nopal verdura (Opuntiaficusindica),variedadesCOPENAF-1,COPENA V-1, Milpa Alta y Atlixco. Se clasificaron en seis estados de desarrollo y se almacenaron a -20 °C. El contenido de ácido ascórbico disminuyó y la actividad de PPO se incrementó al avanzar el desarrollo de los cladodios. La actividad de PPO fue similar en las variedades evaluadas. Los cladodios de la variedad COPENA F-1 presentaron el mayor contenido de fenoles totales y de ácido ascórbico total, mientras que los de Atlixco los menores. El grado de oscurecimiento fue similar en los distintos estados de desarrollo, mostrando Milpa Alta y COPENA F-1 la mayor tendencia a oscurecerse.
