Abstract
The acute and sub-acute toxicity studies were performed in male and female Swiss albino mice as per the guidelines mentioned in OECD. The oral administration of M. tridentata stem extract (MSE) showed no treatment-related mortality and body weight change in mice up to the single dose of 30,000 mg/kg body weight in the acute toxicity study and up to a dose of 30,000 mg/kg/day body weight in the sub-acute toxicity study. Moreover, the clinical signs, body weight, gross pathology, organ weight, hematology (except for platelet count), biochemical analysis, and histopathology did not show significant variation at a medium dose of 15,000 mg/kg/day body weight compared to the control group. However, toxicological signs in behavior, very mild interstitial nephritis, as well as significant variation in platelet count and total protein parameters were observed at a dose of 30,000 mg/kg/day in the 28-day oral toxicity study. Thus, the no-observed-adverse-effect level was determined at a dose of 15,000 mg/kg/day body weight. Based on study results, it is concluded that MSE showed LD50 of greater than 5000 mg/kg/day body weight. Hence, this could be a potential candidature as a future safe pharmaceutical product.

Abstract
In vivo and in vitro anti-allergic activities of ethanol extract of Xenostegia tridentata (L.) D.F. Austin & Staples were investigated using passive cutaneous anaphylaxis reaction assay and RBL-2H3 cell degranulation assay, respectively. The crude ethanol extract exhibited promising activities when compared with the known anti-allergic agents, namely dexamethasone and ketotifen fumarate. The ethyl acetate subfraction showed the highest anti-allergic activity among various sub-partitions and showed better activity than the crude extract, consistent with the high abundance of total phenolic and flavonoid contents in this subfraction. LC-MS/MS metabolomics analysis and bioassay-guided isolation were then used to identify chemical constituents responsible for the anti-allergic activity. The results showed that major components of the ethyl acetate subfraction consist of 3,5-dicaffeoylquinic acid, quercetin-3-O-rhamnoside, kaempferol-3-O-rhamnoside and luteolin-7-O-glucoside. The inhibitory activity of the isolated compounds against mast cell degranulation was validated, ensuring their important roles in the anti-allergic activity of the plant. Notably, besides showing the anti-allergic activity of X. tridentata, this work highlights the role of metabolomic analysis in identifying and selectively isolating active metabolites from plants.

Abstract
The antidiabetic activity of stem-ethanol extract (SE) and the flavonoid-rich fraction (FF) of Merremia tridentata (L.) were investigated on alloxan-induced diabetic mice. Apigenin, cosmosiin, and quercitrin are flavonoids isolated for the first time from stem extracts. In addition, cynaroside was found to be at the highest level in SE and FF with a percentage of 4.375% and 58.430%, respectively. The administration of SE (100 mg/kg) and FF (50, 75 mg/kg) daily for 20 days resulted in a better hypoglycemic effect than the reference drugs, glibenclamide (5 mg/kg), and metformin (10 mg/kg). Furthermore, SE and FF were shown to significantly improve the plasma lipid profiles at the end of the study. Docking's study suggests that cynaroside, cosmosiin, and quercitrin are the most desirable compounds for hypoglycemic effects in many antidiabetic targets. Especially, SE and FF showed strongly α-amylase and α-glucosidase inhibitory activities (IC50 = 1.61-1.72 mg/mL on α-amylase and IC50 = 0.24-0.44 mg/mL on α-glucosidase). Therefore, SE and FF of Merremia tridentata is a potential drug with antidiabetic and hypoglycemic action as indicated by in vivo, in silico, and in vitro studies.

Abstract
The genus Merremia Dennst. ex Endl. (Convolvulaceae) is a rich source of structurally diverse phytochemicals with therapeutic relevance. This review presents the first comprehensive, up-to-date information and research progression on the nutritional value, ethnomedicinal uses, phytochemistry, pharmacological activities, and toxicity of the genus Merremia. Using the key search term “Merremia”, relevant documents and information were retrieved from electronic databases. Relevant documents were uploaded in RStudio with installed bibliometric software packages and used for data retrieval, tabulation, and network visualization. Bibliometric analysis revealed that ca. 55% of the studies related to Merremia were published in the last decade, which can be grouped into four thematic areas: (i) drug formulation, (ii) taxonomy, (iii) chemical analysis, and (iv) treatment of diseases. Ethnomedicinal uses, phytochemistry, and biological activities studies showed that species in the genus are promising medicinal plants with various pharmaceutical potentials. However, clinical studies to validate the efficacy of the reported bioactivities and the mechanisms underlying the various activities are lacking and should constitute a future research focus. Additionally, reports on the nutritional and antinutritional constituents of Merremia species revealed that the species meet high nutritional quality criteria for animals and are therefore suitable for inclusion in livestock diets. The few available investigations on toxicity indicated that most Merremia species are safe for human and animal use but not with prolonged chronic administration.

Abstract
Background Increasing natural drug demand for pharmaceutical uses has encouraged scientifics all over the world to explore medicinal plants recognized as efficient remedies. In this context, extracted oil from pumpkin seeds (Cucurbita pepo L.) is an interesting target, as it is composed with prominent pharmacological properties to possible wound healing treatments. Methods The composition and content of certain bioactive constituents of the cold pressed oil obtained from pumpkin seeds (Cucurbita pepo L.) were analyzed and studied for their wound healing properties. Uniform wounds were induced on the dorsum of 18 rats, randomly divided into three groups. The wounds were photographed, and topically treated with saline solution (control group), 0.13 mg/mm2 of a reference drug (“Cicaflora cream®”), and 0.52 μl/mm2 of pumpkin’s oil each 2 days until the first group is completely healing and so far biopsies were histologically assessed. Results The composition and content of tocopherols, fatty acids, and phytosterols were determined. The results showed an excellent quality of pumpkin oil with high content of polyunsaturated fatty acids (Linoleic acid: 50.88 ± 0.106 g/100 g of total fatty acids), tocopherols (280 ppm) and sterols (2086.5 ± 19.092 ppm). High content of these bioactive components were in agreement with an efficient wound healing by the mean of an in vivo study. In fact, morphometric assessment and histological findings revealed healed biopsies from pumpkin oil treated group of rats, unlike untreated group, and a full re-epithelialization with reappearance of skin appendages and well organized collagen fibers without inflammatory cells. Conclusions This study showed the significance of oil from pumpkin seeds (Cucurbita pepo L.) as a promising drug to healing wounds in animal assays. As a whole, pumpkin’s oil would be recommended in the nutritional and medicinal purposes.

Abstract
OBJECTIVE To investigate the antidiabetic effect of aqueous extract of Merremia tridentata (M. tridentata) root (MTRAE) in normal, glucose-loaded hyperglycemic and streptozotocin (STZ)-induced diabetic rats. METHODS Oral administration of MTRAE at the doses of 50, 100 and 150 mg/kg was studied in normal, glucose-loaded and STZ-diabetic rats. The three doses caused significant reduction in blood glucose levels in all the models. RESULTS The effect was more pronounced in 100 and 150 mg/kg than 50 mg/kg. MTRAE also showed significant increase in serum insulin, body weight and glycogen content in liver and skeletal muscle of STZ-induced diabetic rats while there was significant reduction in the levels of serum triglyceride and total cholesterol. MTRAE also showed significant antilipidperoxidative effect in the pancreas of STZ-induced diabetic rats. The antidiabetic effect of M. tridentata was compared with glibenclamide, a well known hypoglycemic drug. CONCLUSIONS The results indicate that aqueous extract of M. tridentata root possesses significant antidiabetic activity.

Abstract
The aim of this study was to determine the palynological origin, phenolic content, antioxidant and antimicrobial properties of pollen from five Portuguese Natural-Parks [Parque Nacional Peneda Gerês (PNPG); Parque Natural do Montesinho (PNM); Parque Natural do Alvão (PNA); Parque Natural da Serra da Estrela (PNSE) and Parque Natural do Douro Internacional (PNDI)]. Eight families were found in the mixture of bee pollen: Rosaceae, Cistaceae, Boraginaceae, Asteraceae, Fagaceae, Ericaeae, Myrtaceae and Fabaceae. The phenolic compounds content, determined by the Folin-Ciocalteu method, varied between 10.5 and 16.8 mg of gallic acid equivalents/g of extract (mg GAE/g) found in bee pollen from PNM and PNDI, respectively. The free radical scavenging measured showed the highest effective extract - PNM with EC(50) 2.16, followed by PND with 2.24 mg/mL. In the β-carotene bleaching assay the same behaviour as in the DPPH method was verified. We also verified that the presence of pollen differentially affected the growth of bacteria Gram-positive, Gram-negative and yeasts under study, depending this on the microorganism and the pollen used. This is an important study since, as far we know, it is the first time that Portuguese bee pollen from Natural Parks was studied, and their characterization can increase their economic value.
