“…is one of the promising species of the savanna (Biome threatened in Brazil) and its use in shampoos and other related products due to the presence of saponins in various parts of the plant [8]. Saponin comes from the Latin sapo meaning soap, therefore, foams when extracts rich in this substance are stirred in water [9].…”

Ranging from the northeast of Brazil to the north of Minas Gerais, in the region of the savanna, the popularly known JuÃ¡ or Juazeiro (Ziziphus Joazeiro Mart.) is a plant that has great potential medicinal, scientific and economic that can be used in order to contextualize the chemistry teaching that increasingly is becoming fragmented and full of gaps. The aim of this study is to suggest possible concepts and chemistry discipline of content that can be worked by analyzing the properties and benefits of Ziziphus Joazeiro. For it was made a bibliographic review of the plant's properties and their uses can be different and applications in chemistry classroom. There are many chemical concepts that can be worked through juazeiro. In this paper we present some of them such as polarity of the molecules, hydrophilic and hydrophobic substances, antioxidants, solubility, and others that can be studied. It is of great importance the study of plants of a region so threatened as the savanna. This study was the starting so that teachers start to change their way of teaching and find ways to enable student learning takes place in a positive and satisfactory.

“…joazeiro (Rhamnaceae) does not lose its leaves during the dry season, always remaining green (Costa, 2018). This species has several uses such as in popular medicine, in cosmetics and toothpaste, as well as being a source animal food during drought periods (Oliveira, Coelho, Maia, Diógenes & Medeiros-Filho, 2012;Lorenzi, 2016) and in beekeeping (Coelho, Maia, Oliveira & Diógenes, 2011). M. caesalpiniifolia (Fabaceae) (Costa-Filho, Valeri & Cruz, 2013) is a species that has exploited (Freitas, Pinto, Praxedes, Nogueira & Ribeiro, 2011;Nogueira, Ribeiro, Freitas, Matuoka & Souza, 2012) for its wood and energy use (Costa-Filho et al, 2013).…”

Allelopathy is an ecological mechanism that influences the development of neighboring plants. The objective was to evaluate the allelopathic potential of Cenostigma bracteosum and Sarcomphalus joazeiro on seed germination and initial growth of Mimosa caesalpiniifolia seedlings. Seeds of this species were placed to germinate on paper towel substrate, and then moistened with extracts from dry leaf of S. joazeiro and C. bracteosum at 1.0; 2.5; 5.0 and 10.0% (w.v-1), and control (0.0% - distilled water) at 25 °C. The variables evaluated: germination, germination speed index, primary root length and root system dry weight of the seedlings. Positive allelopathic effects of S. joazeiro leaf extracts were observed on the vigor of M. caesalpiniifolia; when used in low concentrations (up to 2.6%), C. bracteosum leaf extracts stimulated germination of M. caesalpiniifolia seeds and showed more severe toxic effects when exposed to high concentrations (5.0%). S. joazeiro leaf extracts favor the germination and vigor of M. caesalpiniifolia seedlings, while C. bracteosum leaf extracts cause phytotoxic effects on seed germination and initial growth of M. caesalpiniifolia seedlings from the concentration of 5%. Therefore, there are indications of benefits for regeneration or associated forest composition between M. caesalpiniifolia and S. joazeiro.

“…Thus, research on allelopathy may lead to the production of bioherbicides to be used in weed control (Oliveira et al, 2012), providing a viable alternative for the control of species that affect crops, and replacing agricultural industrial inputs with biological herbicides, resulting in balanced pastures and free of pesticides. At the same time they would also prevent serious damage to nature such as degradation and contamination of the water table due to the increasing use of chemicals (Carvalho et al, 2002).…”

Through secondary metabolism, plants produce chemical compounds which when released into the environment can have effects on other species, such effect is called allelopathy. In this research we evaluated the Cordia oncocalyx (Boraginaceae) allelopathic potential against two weed species, Cenchrus echinatus and Calotropis procera, as well as quantified its phenolic compounds using HPLC-DAD. The experimental design was completely randomized with six treatments and one control group (distilled water). Each treatment consisted of four replicates with 25 seeds each, totaling 100 seeds per treatment. The variables analyzed were: germinating potential, germination velocity and seedling development. The hot and cold infusion extracts were prepared with 50 g of each of the three parts of the donor plant (bark, leaves and roots) immersed in 500 ml of distilled water at 100 °C (hot infusion) and 25 °C (cold infusion). The experiments were mounted in Petri dishes having substrate filter paper embedded in 3 mL of the extracts (treatments) and conducted in a germination chamber. Hot and cold infusion extracts of the C. oncocalyx leaves, barks and roots presented allelopathic activity on C. echinatus and C. procera germination and development, with the hot bark extract promoting such effect with a greater intensity. The allelopathic effect observed may be due to the presence of allelochemicals such as caffeic acid, quercentin and kaempferol present in C. oncocalyx leaves, barks and roots.
