Chlorogenic acid and caffeine are among the important components in coffee beans, determining the taste and aroma. In addition, phenols and antioxidants content possess vital health values. The main aim of this study is to determine the levels of caffeine and chlorogenic acid in several coffee samples of different origins and degrees of roasting. The coffee samples were extracted using hot water. The levels of caffeine and chlorogenic acid were quantified using high-performance liquid chromatography (HPLC) equipped with a diode array detector, a reverse phase system, and an ODS column (C18). Total phenol and antioxidant contents were previously determined for the same samples. The results showed that the highest content of caffeine was found in the medium roasted coffee (203.63 mg/L), and the highest content of chlorogenic acid content was found in the green coffee (543.23 mg/L). The results demonstrated a negative correlation between the chlorogenic acid levels with the degree of roasting, while it showed a positive correlation between the caffeine levels with the degree of roasting till a certain point where the levels dropped in the dark roasted coffee. The origin of coffee samples did not show any effect on any of the measured variables. Antioxidant effects of coffee samples were largely determined by chlorogenic acid content.

Phenolic and antioxidant compounds have received considerable attention due to their beneficial effects on human health. The aim of this study is to determine the content of total phenols and antioxidants in fifty-two coffee samples of different origins, purchased from the Jordanian local market, and investigate the effect of the degree of roasting on the levels of these compounds. The coffee samples were extracted using the hot water extraction method, while Folin–Ciocalteu (FC) and 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay methods were used to analyze these compounds. The results showed that the highest content of total phenol (16.55 mg/g equivalent to GAE) was found in the medium roasted coffee, and the highest content of antioxidants (1.07 mg/g equivalent to TEAC) content was found in the green coffee. Only light and medium roasted coffee showed a significant correlation (p < 0.05, R² > 0.95) between the average of total phenolic and antioxidant content. A negative correlation between the antioxidant content and the degree of roasting (p < 0.05, R² > 0.95) were shown, while it did not correlate with phenolic contents. Previously, a positive correlation between antioxidant and chlorogenic acids content was observed, with no correlation between the origin of coffee samples nor heavy metal content, which was previously determined for the same coffee samples. These findings suggest that the antioxidant content for coffee extracts is largely determined by its chlorogenic acid content, rather than the coffee origin or total phenolic and heavy metals content.

Background: Nutrients are widely used for treating illnesses in traditional medicine. Ginger has long been used in folk medicine to treat motion sickness and other minor health disorders. Chronic non-healing wounds might elicit an inflammation response and cancerous mutation. Few clinical studies have investigated 6-gingerol’s wound-healing activity due to its poor pharmacokinetic properties. However, nanotechnology can deliver 6-gingerol while possibly enhancing these properties. Our study aimed to develop a nanophytosome system loaded with 6-gingerol molecules to investigate the delivery system’s influence on wound healing and anti-cancer activities. Methods: We adopted the thin-film hydration method to synthesize nanophytosomes. We used lipids in a ratio of 70:25:5 for DOPC(dioleoyl-sn-glycero-3-phosphocholine): cholesterol: DSPE/PEG2000, respectively. We loaded the 6-gingerol molecules in a concentration of 1.67 mg/mL and achieved size reduction via the extrusion technique. We determined cytotoxicity using lung, breast, and pancreatic cancer cell lines. We performed gene expression of inflammation markers and cytokines according to international protocols. Results: The synthesized nanophytosome particle sizes were 150.16 ± 1.65, the total charge was −13.36 ± 1.266, and the polydispersity index was 0.060 ± 0.050. Transmission electron microscopy determined the synthesized particles’ spherical shape and uniform size. The encapsulation efficiency was 34.54% ± 0.035. Our biological tests showed that 6-gingerol nanophytosomes displayed selective antiproliferative activity, considerable downregulation of inflammatory markers and cytokines, and an enhanced wound-healing process. Conclusions: Our results confirm the anti-cancer activity of PEGylated nanophytosome 6-gingerol, with superior activity exhibited in accelerating wound healing.

This study aims to investigate the anti-hyperlipidaemic effect of ethanolic leaf extract of Equisetum ramosissimum. 2,2-Diphenyl-1- picrylhydrazyl assay for antioxidants, Folin-Ciocalteu, AlCl₃, and UHPLC-MS/MS analysis, focusing on phenols and flavonoid content were performed. Anti-hyperlipidemic effect of the extract on lipid profile and body weight was evaluated alone or in combination with Atorvastatin in rats. The extract was shown to contain phenols (0.032±0.001 µg/g, equivalent to gallic acid), flavonoids (0.044±0.003 mg/g, equivalent to quercetin), and antioxidant IC₅₀ value of (1000.00±0.78 µg/mL). UHPLC-MS/MS analysis revealed the presence of 8 different phenols and flavonoids. An in vivo study on healthy standard diet-fed animals and an induced hyperlipidaemic model showed a significant (P < 0.05) reducing effect of the extract alone and in combination with Atorvastatin on serum lipid profile. These findings revealed the potential advantages of the extract alone and in combination with statins for preventing or treating hyperlipidaemia, but need to be further explored.

The Pharmacy One™ Poising Call Center (P¹PCC), located in Amman, Jordan, was created to address deficiencies identified by the pharmacy service, including in the management of poisoning cases. The aims of this study were to analyze the patterns of poisoning cases reported to the P¹PCC and to describe the role of the P¹PCC pharmacist in ensuring preparedness and managing the response to poisoning cases. In addition, the information from these interventions was used to survey human poisoning in Jordan. This is a retrospective descriptive study of acute poisoning incidents in the Jordanian population, as recorded by the P¹PCC during the period 2014‐2018. Inquiries received by the P¹PCC were recorded on a predesigned form. The year, patient demographics, toxic agent involved, and circumstances of the poisoning event were all fully documented utilizing Oracle and Excel spreadsheets. A total of 1992 poisoning incidents were reported to the P1PCC, predominately (68.59%) via 911 phone calls. Reports were predominantly from males (1.67:1). Children were the second most common age group after adolescents (22.62% and 42.49%, respectively). The most frequent causative nonpharmaceutical agents were household products (17%) in preschool children and animal bites (20%) in adolescents. Most of the poisoning incidents (74.63%) occurred at home. Unintentional poisoning (54.12%), with mild medical outcomes (61.45%), accounted for most of the poisoning incidents caused by exposure to household products. These data may represent the most recent picture of poisoning incidents in Jordan. Emergency medical services were provided by experienced pharmacy practitioners at the P¹PCC, to respond to emergency needs in the community in a professional manner. Therefore, the need for unnecessary hospitalization and the cost of ambulance dispatch were minimized, which are highly valuable outcomes.

Poison control centers provide surveillance data that can be used to estimate the magnitude of poisoning cases and the level of public awareness and to evaluate control measures. The aim of this study is to describe the drug‐related poisoning queries received by the Pharmacy One™ Poisoning Call Center (P¹PCC) in Jordan. This is a retrospective descriptive study of the acute drug‐related poisoning incidents in the Jordanian population recorded by the P¹PCC during the 2014‐2018 period. The inquiries received were recorded on a predesigned form. The demographic data, including the age and the sex of the patient, the route of and reason for exposure and the drug therapeutic groups, in addition to medical outcomes, were extracted utilizing computerized Oracle and Excel spreadsheets. During the period of evaluation, 900 drug‐related poisoning incidents were reported to the P¹PCC. The majority of calls (48.5%) were received via 911, followed by the public (48.56%) and healthcare professionals (27.1%). More than half of the poisoning incidents were recorded among males (52.5%). Adults were the most affected group (40.5%), followed by children (34.0%). Unintentional exposure was the most common cause of poisoning (58.6%), followed by suicide attempts (25.3%). Nonsteroidal anti‐inflammatory drugs and paracetamol caused the majority of the reported cases. Poisoning incidents were mainly classified as mild to moderate (56.1%), while only 16.6% were severe. The P¹PCC has demonstrated an important and vital role in improving patient safety and providing education on rational drug use. Reflections on these data can be used to increase public awareness in promoting the rational use of medications among Jordanian citizens.
