Miller, is an unconventional food plant native to South America. This study aimed to investigate the influence of different ultrasonic extraction times (10, 20, 30, and 40 min) on the phytochemical profile, antioxidant and antibacterial activities of ethanolic extracts obtained from lyophilized Miller (ora-pro-nobis) leaves, an under-researched plant. Morphological structure and chemical group evaluations were also conducted for the lyophilized leaves.

In this study, the peels of the yellow passion fruit ( flavicarpa) were used to develop a flour that was evaluated in terms of its physicochemical, microscopic, colorimetric, and granulometric characteristics, its total phenolic compound and carotenoid contents, and its antioxidant capacity. Fourier Transform Infrared (FTIR) spectroscopy measurements were employed to investigate the constituent functional groups, compounds' chemical profiles were assessed by Paper Spray Mass Spectrometry (PS-MS), and the compound's chemical profiles were evaluated by Ultra-Performance Liquid Chromatography (UPLC). This flour presented a light color, heterogeneous granulometry, high carbohydrate, carotenoid, and total phenolic compound contents with high antioxidant capacity.

Jabuticaba () and jambolan () fruits are rich in phenolic compounds with antioxidant properties, mostly concentrated in the peel, pulp, and seeds. Among the techniques for identifying these constituents, paper spray mass spectrometry (PS-MS) stands out as a method of ambient ionization of samples for the direct analysis of raw materials. This study aimed to determine the chemical profiles of the peel, pulp, and seeds of jabuticaba and jambolan fruits, as well as to assess the efficiency of using different solvents (water and methanol) in obtaining metabolite fingerprints of different parts of the fruits.

This integrative review aims to identify the main flavonoids present in some species of the Myrtaceae family. Studies published between 2016 and 2022 were selected, specifically those which were fully available and written in Portuguese, English, or Spanish, and which were related to the fruits araçá (), cambuí (), gabiroba (), jabuticaba (), and jambolan (). Scientific studies were gathered and selected in Google Scholar, Scielo, and Science Direct indexed databases, out of which 14 were about araçá, 7 concerned cambuí, 4 were about gabiroba, 29 were related to jabuticaba, and 33 concerned jambolan, when we observed the pre-established inclusion criteria.

Article Synopsis
  • This study examined the physicochemical traits and bioactive compound production of a plant (Mill.) across different harvest times, focusing on chemical profiles and antioxidant properties.
  • Analytical techniques like paper spray mass spectrometry (PSMS) and high-performance liquid chromatography (HPLC) were used to assess phenolic acids, flavonoids, and various chemical characteristics such as pH and total soluble solids.
  • The findings revealed that while most chemical traits remained stable across seasons, certain compounds like azelaic acid appeared only in winter-harvested leaves, with no significant seasonal differences in bioactive compound production or antioxidant activity.

Angiostrongylus costaricensis is a parasite that causes abdominal angiostrongyliasis in humans. The treatment for it includes the use of anti-inflammatory drugs, despite the lack of studies to justify this approach. The objective of this paper was to evaluate the effect of betamethasone and Arctium lappa on the evolution of intestinal lesions induced by this parasite.
