Rhodophiala bifida (Herb.) Traub, Amaryllidaceae, is a species native to South America known to produce alkaloids with potential pharmacological uses such as montanine, which has anti-inflammatory potential. R. bifida could be applied as a natural source of montanine. It is important to understand the genetic diversity of this species in order to a...

Sixteen known compounds, including three lignan glycosides (1–3), seven phenolic glycosides (4–10), three glycosides (11–13), and three flavonoids (14–16), were isolated from the rhizomes of Actinidia kolomikta (Rupr. & Maxim.) Maxim., Actinidiaceae. Their structures were elucidated through extensive spectroscopic analyses and comparison with those...

Antioxidant compounds are increasingly attracting more attention by neuropharmacology studies due to the property of preventing brain damage. This study aimed to evaluate the supposed enhancement of antidepressant potentiality of a flavonoid-rich extract and investigate the new bioactive compounds from Passiflora edulis f. flavicarpa leaves. Quanti...

Acute kidney injury can be induced by nonsteroidal anti-inflammatory drugs, such as ibuprofen and diclofenac. In seeking to identify functional foods with a positive effect beyond basic nutrition, the antioxidant-rich artichoke (Cynara scolymus L., Asteraceae) inflorescence was biochemical investigated for nephroprotective activity. The edible arti...

This study compared the influence of mechanical damage and drying on the chemical composition of Mikania glomerata Spreng. and Mikania laevigata Sch.Bip. ex Baker, Asteraceae, leaves. Leaves were collected 1–24 h after damage. Oven-drying at 40° C and shade-drying at ambient temperature were compared to lyophilization. Samples were extracted in 70%...

The objective of this study was to evaluate the acaricidal activity of the volatile oils of three species of Croton, Euphorbiaceae, against the cattle tick Rhipicephalus microplus. The volatile oils were obtained by hydrodistillation, analyzed by GC-MS and GC-FID and their acaricidal activity was evaluated by the larval packet test and adult immers...

Citrus fruits are recognized as an important source of bioactive molecules such as limonin and nomilin. However, these molecules exhibit low bioavailability, therefore, obtaining these molecules using biotechnological techniques may be an alternative to harvesting them directly from fruits. The aim of this study was to quantify and identify limonoi...

The pericarp of Trapa natans L., an annual aquatic floating herb belonging to Lythraceae family, is used as a folk medicine in China. In this study, extracts of Trapa natans pericarp were tested both in vitro and in vivo through a high-fat diet with a single medium dosage streptozotocin injection induced type 2 diabetic mice. Different solvent extr...
