Abstract

The aim of this study was to evaluate the effect of cultivation locality on the antioxidant compounds and the antioxidant capacity concerning two Moroccan prickly pear cultivars. Various extracts were prepared from two distinct cultivars by organic extraction using a Soxhlet for three plant parts (seeds, cladodes, and flowers). In this context, the potential of polyphenolic extracts from opuntia ficus indica and opuntia megacantha were evaluated to determine their antioxidant compounds and antioxidant activities. Quantitative analysis of the phenolic compounds shows that the extracts of the flowers had the highest content of phenolic and flavonoids (50.01 ± 0.02 mg equivalent of Gallic Acid per gram of dry mass and 13.33 ± 0.14 mg equivalent of quercetin per gram of dry mass). The antioxidant activity varied from (IC50: 0.201 ± 0.002) to (IC50: 0.96 ± 0.02 mg/ml) by DPPH assay, and (EC50: 2.40 ± 0.03 to 10.03 ± 0.08) by FRAP method.

Rationale

Lifestyles and unhealthy eating habits can intensively increase the production of reactive oxygen species in the human body which can create a disorder between the generation of these species and the body's antioxidant defenses [1]. This imbalance is called oxidative stress, which can cause various pathologies such as incurable cancers and cardiovascular diseases. For prevention, we need to look for a way to prevent oxidative stress and to seek additional intake of antioxidant compounds. In

Plant materials sites

Morocco is a country located in North West Africa. It is characterized by a very different climate depending on the region. In this work, we harvested the plant materials in different regions; each region is characterized by specific geographic coordinates and a type of climate. El Ajhar et al. [13], showed in their study the classification of the types of climates of regions of Morocco according to precipitation during the 1980–2015 period (Table 1). Therefore, the regions Rabat, Taza, and Al

Data, value and validation

Medicinal plants, especially cereals, fruits, vegetables, are the subject of numerous studies for their potential role in the prevention and control of human diseases. They give us a wealth of all kinds of phytochemical compounds as well as an excellent nutritious diet beneficial for health, the treatment of chronic patients becomes exploited bioactive compounds such as antioxidants that have a potential for scavenging free radicals in the human body. The added value of natural antioxidants

Conclusion

Some studies indicated that the consumption of vegetables and fruits can neutralize free radicals of the body thanks to the antioxidants which they contain. This can help in the prevention or treatment of diseases associated with oxidative stress. For this reason, this study includes the different parts (flowers, cladodes, seeds) of both cultivars of Moroccan cactus. through, its phenolic compounds and its antioxidants. The highest yield is obtained by seeds extract from Tiznit (16.42%).
