“…Consequently, the extraction process was shortened without the need for a second filtration step. However, higher yields in the extraction process do not necessarily indicate higher efficiency [ 15 ]. Furthermore, difficulties in handling lyophilized extracts are encountered in these methods because, despite generally having a higher mass without precipitation, the extracts exhibit viscous and adhesive properties.…”

Plinia cauliflora (Mart.) Kausel, popularly known as jabuticaba, possesses bioactive compounds such as flavonoids, tannins, and phenolic acids, known for their antioxidant, antibacterial, wound healing, and cardioprotective effects. Therefore, this study aimed to standardize the P. cauliflora fruit peel extraction method, maximize phenolic constituents, and evaluate their antioxidative and antimicrobial effects. Various extraction methods, including vortex extraction with and without precipitation at 25, 40, and 80 °C, and infusion extraction with and without precipitation, were performed using a completely randomized design. Extraction without precipitation (E − P) showed the highest yield (57.9%). However, the precipitated extraction (E + P) method displayed a yield of 45.9%, higher levels of phenolic derivatives, and enhanced antioxidant capacity. Major compounds, such as D-psicose, D-glucose, and citric acid, were identified through gas chromatography–mass spectrometry (GC-MS) analysis. Ultra-high-performance liquid chromatography–tandem mass spectrometry (UHPLC-MS/MS) analysis identified citric acid, hexose, flavonoids, tannins, and quercetin as the major compounds in the extracts. Furthermore, the extracts exhibited inhibitory effects against Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli bacteria. In conclusion, the E + P method efficiently obtained extracts with high content of bioactive compounds showing antioxidant and antimicrobial capacities with potential application as a dietary supplement.

Echinodorus grandiflorus and Echinodorus macrophyllus are medicinal plants that are widely used in Brazilian folk medicine. The aims of this study were to evaluate the effect of oven drying with ventilation on the chromatographic profile of volatile compounds and to compare the leaf anatomy and volatile compounds of different commercial E. macrophyllus (Kunth) Micheli and E. grandiflorus Mich. Samples. The components found in fresh and dried samples were extracted by SPME and analysed by GC-MS, and the anatomical features of the leaves were observed microscopically. A total of 46 compounds were identified; five compounds were present in the dried and fresh samples of E. grandiflorus and all of the commercial samples. The anatomy analyses confirmed the authenticity of the species. Apparent differences in the volatile composition between the species were observed, allowing the identification of chemical marker. The results showed that commercial establishments do not conform to regulations, and the techniques used were effective for the characterization of volatile compounds and for quality control of medicinal plants.

Ononis natrix is one of the wild plants from the Fabaceae family. The infusion of the plant is traditionally used for the therapy of urinary tract disorders. Urolithiasis is a deposit of stone components (oxalate, calcium, uric acid, magnesium, cysteine) in the kidneys. The formulation of stones occurs in consecutive stages. Nephrolithiasis is consecration as one of the most common Kidney diseases. Numerous phytomolecules have several functions in the management of urolithiasis. The aim was to investigate the possible litholytic effect of O. natrix extracts against calcium oxalate urinary stones. Stones were collected from urolithiasis patients after surgical procedures. The type of the stones was determined by FTIR spectroscopy, selected of calcium oxalate type, and the experiment was performed by incubating three concentrations (0.5, 1, 2) g/L of aerial parts and root extracts (ethanolic 70% and aqueous) in-vitro with physiological saline (NaCl 9 g/L) for 6 weeks. The results were presented as dissolution rate % compared to positive control (sodium citrate 3 mmol/L) and negative control (physiological saline 9 g/L). The ethanolic 70% extract of the aerial parts in the concentration of 2 g/L showed the highest litholytic activity (47.73% ± 0.66%) at the end of the experiment (week 6) followed by the concentration of 1 g/L (34.81 %± 1.25%) with statistically significant difference (P <0.0001) in comparison with sodium citrate (4.18% ± 2.13%) and physiological saline (1.37% ± 0.22%). The results exhibit that the litholytic activity of O. natrix extracts was higher in the aerial parts than the roots, it was also higher in the ethanolic extracts than the aqueous extracts, which is related to their flavonoid content.
