RESUMEN
Pumpkin is a well-known multifunctional ingredient in the diet, full of nutrients, and has opened new vistas for scientists during the past years. The fruit of pumpkin including the flesh, seed, and peel are a rich source of primary and secondary metabolites, including proteins, carbohydrates, monounsaturated fatty acids, polyunsaturated fatty acids, carotenoids, tocopherols, tryptophan, delta-7-sterols, and many other phytochemicals. This climber is traditionally used in many countries, such as Austria, Hungary, Mexico, Slovenia, China, Spain, and several Asian and African countries as a functional food and provides health promising properties. Other benefits of pumpkin, such as improving spermatogenesis, wound healing, antimicrobial, anti-inflammatory, antioxidative, anti-ulcerative properties, and treatment of benign prostatic hyperplasia have also been confirmed by researchers. For better drug delivery, nanoemulsions and niosomes made from pumpkin seeds have also been reported as a health promising tool, but further research is still required in this field. This review mainly focuses on compiling and summarizing the most relevant literature to highlight the nutritional value, phytochemical potential, and therapeutic benefits of pumpkin.
RESUMEN
Aim of present study was to screen medicinal plants for flukicidal activity in vitro to develop alternative sources of treatment for trematodes infection. For this purpose, crude methanolic extracts (CME) of Cymbopogn jwarancusa and Conyza canadensis were prepared and live adult flukes viz; Fasciola gigantica, and Paramphistomum cervi isolated from liver and bile ducts of slaughtered buffalo were subjected to different drug concentrations as well as positive and negative control. Motility inhibition and paralysis leading to the death of parasites was considered as flukicidal activity of plants extracts. The results revealed that CME of C. jwarancusa and C. canadensis showed significant (P<0.05) flukicidal activity compared to positive control. Also there was a significant effect of different concentrations (P<0.05) and exposure of time on the flukes (P<0.05). Furthermore, ED50 for C. jwarancusa and C. canadensis against F. gigantica were 13.1 and 41.4 mg/ml, respectively. In the case of P. cervi, it was 10.8 and 29.0 mg/ml. It can be concluded that both tested plants showed greater flukicidal activity as compared to positive control with Albendazole till the 8(th) hr. These potent plants needs further studies invivo to elucidate their mode of action.
