Abstract
Coumarins are benzopyrones found in several plant genera, including Pterocaulon (Asteraceae). These compounds represent an important source of new treatments, especially as antimicrobial and antifungal agents. In this study, two coumarin-rich extracts from Pterocaulon balansae using green technologies were obtained through aqueous maceration (AE) and supercritical fluid extraction (SFE). Such extracts were incorporated into nanoemulsions (NAE and NSFE) composed of a medium-chain triglyceride oil core stabilized by phospholipids. The nanoemulsions exhibited droplet sizes between 127 and 162 nm, pH above 5.0, and viscosity of approximately 1.0 cP, properties compatible with the topical route. The coumarins permeation/retention from formulations through ear porcine skin using Franz-type diffusion cells were evaluated. Whatever the extract, coumarins were distributed in skin layers, especially in the dermis in both intact and impaired (tape stripping) skin. In addition, a significant increase in coumarins that reached up to the receptor fluid was observed for impaired skin, with increases of approximately threefold for NAE and fourfold for NSFE. Finally, antifungal activity of nanoemulsions was evaluated according to minimum inhibitory concentrations, and the values were 250 µg/mL for all strains tested. The overall results demonstrated the feasibility of incorporating P. balansae extracts into nanoemulsions and showed a potential alternative for the treatment of sporotrichosis.

Abstract
Experimental mixture design was drawn to evaluated the effects of the interactions between water, methanol and ethyl acetate mixtures on the extraction efficiency of coumarin (1,2-benzopyrone) from Dipteryx odorata seeds. Solvents were defined considering those preferred as green solvents for natural products extraction. Ultrasonic-assisted extraction method developed was simple, fast, low cost and highly selective. Analyses were performed by reversed-phase liquid chromatography using acetonitrile/water (40:60 v/v) as mobile phase, a C18 column, and a diode-array detector at 274 nm. Results were evaluated in linear, quadratic, special cubic, and full cubic models. The Full cubic model showed the best extraction results with a total error of 3.67%. The optimal extraction point was obtained using 15% water, 20% methanol, and 65% ethyl acetate (v/v). Based on the Guide for the Expression of Uncertainty in Measurements and Monte Carlo simulations, the uncertainty expression presented deviations of 1.18 and 1.64, respectively, showing the reliability of the analytical method. D. odorata seeds are popularly used in the pharmaceutical, food, and cosmetic applications due to high content of coumarins. However, the yield of coumarins extraction depends on the proper choice of the extraction method and solvents. The ternary mixture was optimized and resulted in 3.82% coumarin (weight/seed), which, compared to literature, showed a good increase over that obtained using common solvents, without considering the mathematical modeling.

Abstract
Trichomonas vaginalis causes trichomoniasis, a nonviral sexually transmitted infection with a high prevalence worldwide. Oral metronidazole is the drug of choice for the treatment of this disease, although high levels of T. vaginalis resistance to this agent are well documented in the literature. This study describes the anti-T. vaginalis activity of an optimized coumarin-rich extract from Pterocaulon balansae. Optimization was performed to maximize extraction of total coumarins by means of a 3-level Box-Behnken design, evaluating the effect of three factors: extraction time, plant : solvent ratio, and ethanol concentration. Optimum conditions were found to be 5 h extraction time and a plant : solvent ratio of 1% (w/v) and 60% (v/v) ethanol, which resulted in approximately 30 mg of total coumarins/g of dry plant. The coumarin-enriched extract exhibited a minimum inhibitory concentration of 30 µg/mL and an IC50 of 3.2 µg/mL against T. vaginalis, a low cytotoxicity, and a high selectivity index (18 for vaginal epithelial cells and 16 for erythrocytes). The coumarins permeation/retention profile through porcine vaginal mucosa was evaluated in Franz-type diffusion cells. After 8 h of kinetics, coumarins were detected in the tissue (4.93 µg/g) without detecting them in the receptor compartment. A significant increase of coumarins in the mucosa layers (8.18 µg/g) and receptor compartment (0.26 µg/g) was detected when a T. vaginalis suspension (2 × 105 trophozoites/mL) was previously added onto the mucosa. No alterations were visualized in the stratified squamous non-keratinized epithelium of the porcine vaginal mucosa after contact with the extract. Overall, these results suggest that the P. balansae coumarin-rich extract may have potential as a treatment for trichomoniasis.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Species of the genus Pterocaulon (Asteraceae) are used in different parts of the world for treating skin and liver diseases, as well as disorders of the respiratory system, among others. AIM OF THE STUDY This review aims to discuss the present state of the art concerning the ethnobotanical uses, secondary metabolites and biological effects of Pterocaulon species and their chemical components. MATERIALS AND METHODS The available information on the genus Pterocaulon was gathered from scientific databases (Web of Science, Pubmed, ScienceDirect, Scopus, ChemSpider, SciFinder ACS Publications, Wiley Online Library). Information was also obtained from local publications, M.Sc. and Ph.D. dissertations. All studies on the ethnobotany, phytochemistry, pharmacology and toxicology of the plants until December 2017 were included in this review. RESULTS Approximately 40 coumarins and 30 flavonoids have been isolated from Pterocaulon species. Coumarins have been considered the chemotaxonomic markers in the genus and the most active components. Pharmacological studies carried out with extracts and isolated compounds revealed in vitro bioactivities that include antifungal, antiviral, and cytotoxicity. Most of the pharmacological investigations were not correlated with traditional uses of the plants. CONCLUSIONS Pterocaulon species, a rich source of coumarins, have great ethnomedical potential. Nevertheless, further studies into the pharmacological activities are necessary since none of the purported effects of these plants was fully assessed. In-depth research regarding the toxicity are also required to ensure the safety of these medicinal plants.

Abstract
Supercritical fluid technologies offer a propitious method for drug discovery from natural sources. Such methods require relatively short processing times, produce extracts with little or no organic co-solvent, and are able to extract bioactive molecules whilst minimising degradation. Supercritical fluid extraction (SFE) provides a range of benefits, as well as offering routes to overcome some of the limitations that exist with the conventional methods of extraction. Unfortunately, SFE-based methods are not without their own shortcomings; two major ones being: (1) the high establishment cost; and (2) the selective solvent nature of CO2, i.e., that CO2 only dissolves small non-polar molecules, although this can be viewed as a positive outcome provided bioactive molecules are extracted during solvent-based SFE. This review provides an update of SFE methods for natural products and outlines the main operating parameters for extract recovery. Selected processing considerations are presented regarding supercritical fluids and the development and application of ultrasonic-assisted SFE methods, as well as providing some of the key aspects of SFE scalability.
