ABSTRACT
Background: Opuntia elatio Mill is a xerophytic plant with potentially active nutrients. It is traditionally appreciated for its pharmacological properties; however, the scientific information on this plant is insufficient. Objective: The present study evaluates the antinociceptive and anti‑inflammatory action of prickly pear. Materials and Methods: Writhing and tail‑immersion tests were carried out to evaluate analgesic action, while the carrageenan‑induced paw edema and neutrophil adhesion tests were conducted in Albino wistar rats to assess anti‑inflammatory action. Results: ED50 values of the fruit juice in writhing, tail immersion, and paw edema test were 0.919, 2.77, and 9.282 ml/kg, respectively. The fruits of Opuntia produced analgesic and anti‑inflammatory action in a dose‑dependent manner. Conclusion: The results establish the folklore use of prickly pear may be due to the presence of betacyanin and/or other phenolic compounds.
ABSTRACT
The present investigation deals with the development of agro-techniques for Opuntia ficus indica (Prickly pear)-OFI cultivation. Standardization and development of best spacing for opuntia plantation, fertilization imposition to achieve good fruit and biomass yield and alternatively fruit quality and biomass parameters was observed and concluded as the better agro-technique among the all imposed treatments. The effect of different spacing and fertilizers composition treatment on cladode yield, fruit yield, harvesting index, stem area index (SAI), Total soluble solids (TSS), Titrable acidity and Ascorbic acid (Vit-C). Correlation studies of treatments revealed that all the six characters of cladode yield, harvest index, Stem area index, TSS, TA and Vit-C exhibited non significant, positive correlation with fruit yield.
ABSTRACT
To extract, quantify, and evaluate the phenolic content in Opuntia ficus-indica skin for their antioxidant capacity with three different methods (ABTS, DPPH, and lipid oxidation) and to optimize the extraction conditions (time, temperature and ethanol concentration) in a reflux system. Methods: The extraction process was done using a reflux system. A San Cristobal II experimental design with three variables and three levels was used. The variables evaluated were time of extraction (h), concentration of ethanol (%, v/v) and temperature (°C). The extraction process was optimized using a response surface methodology. Results: It was observed that at higher temperature more phenolic compounds were extracted, but the antioxidant capacity was decreased. The optimum conditions for phenolic compounds extraction and antioxidant capacity mixing the three methods were as follows: 45% of ethanol, 80 °C and 2 hours of extraction. Values obtained in our results are little higher that other previously reported. Conclusions: It can be concluded the by-products of Opuntia ficus-indica represent a good source of natural antioxidants with possible applications in food, cosmetics or drugs industries.
ABSTRACT
We investigated dietary effects of prickly pear cactus (Opuntina ficus-indica) on plasma lipids, platelet aggregation (PA), hemolysis, plasma TBARS and liver enzymes. Twenty eight volunteer diving women in Jeju island had daily 20 g cactus tea containing 27% prickly pear cactus (PPC) powder for 4 weeks, and data for the study subjects were analyzed, on the basis of diagnostic criteria for blood pressure (BP)(> or = 140/90 mmHg), plasma cholesterol (> or = 200 mg/dL) and triglyceride (> or = 150 mg/dL). The subjects with higher BP had higher plasma total cholesterol (TC) and triglyceride (TG) concentrations than those with normal BP. Those with higher TC also had higher TG. Subjects with normal BP or normal TC had higher initial slope of PA than their higher counterpart in BP and TC. PPC intake decreased plasma TG in those with higher BP. PPC intake significantly decreased the elevated initial slope in groups with normal BP, TC, and TG. Hemolysis after PPC intake decreased significantly in all the subjects and plasma TBARS decreased in the subjects with higher plasma TC and higher TG. Glutamic-oxaloacetic transaminase (GOT) significantly increased and total bilirubin significantly decreased in all the subjects after PPC intake. The present study with diving women showed that beneficial effects of short term intake of prickly pear cactus might differ depending on the subject conditions in term of blood pressure, and plasma lipids. However, long term usage of prickly pear cactus may provide preventive effects of cardiovascular diseases to all the population, presumably by hypolipidemic, antithrombotic, and antioxidant actions of its bioactive flavonoids and soluble fiber.

Opuntia ficus-indica Mill. and Nopalea cochenillifera (L.) Lyons (Cactaceae) are alternative food sources for cattle in drought areas of the Northeastern Region of Brazil. Diaspis echinocacti (Bouché) is the unique pest of these Cactacea species and it was previously detected on the following native host plants: Cereus jamacaru DC., Melocactus sp., Opuntia dillenii Haw. and O. inamoena K. Schum. The new record of native hosts are Cereus gounellei (Weber) Luetzelb., C. squamosus Gërke. and the exotic C. hildemannianus K. Schum., from drought areas; Pereskia grandifolia Haw. and Epiphyllum oxypetalum Haw., native species from tropical forest used as ornamental plants. D. echinocacti has not infested O. monacantha Haw. in the field and in laboratory bioessays. The dissemination of the neonate scale insect transported on the body surface of the predators Chilocorus nigrita (Fabricius) and Zagreus bimaculosus (Mulsant) Coccinellidae: Chilocorinae) was registered for the first time.
Opuntia ficus indica Mill. e Nopalea cochenillifera (L.) Lyons (Cactaceae) representam fontes alternativas de alimento para o gado nas regiões secas do Nordeste do Brasil. Diaspis echinocacti (Bouché), único inseto-praga destas forrageiras, foi detectado inicialmente nas seguintes cactáceas nativas: Cereus jamacaru DC., Melocactus sp., Opuntia dillenii Haw. e O. inamoena K. Schum. Os novos registros de plantas-hospedeiras são: Cereus gounellei (Weber) Luetzelb., C. squamosus Gërke. (nativas) e C. hildemannianus K. Schum., exótica, todas provenientes de regiões secas; Pereskia grandifolia Haw. e Epiphyllum oxypetalum Haw., da floresta tropical e utilizadas como plantas ornamentais. D. echinocacti não foi observada em O. monacantha Haw. no campo, nem conseguiu se estabelecer em raquetes desta planta em condições de laboratório. A disseminação de ninfas neonatas da cochonilha transportadas no corpo dos predadores Chilocorus nigrita (Fabricius) e Zagreus bimaculosus (Mulsant) (Coccinellidae: Chilocorinae) foi registrada pela primeira vez.
