“…An aqueous plant extract of E. alata has proved efficient when used as a reducing and capping agent for the synthesis of copper oxide nanoparticles [187]. Similarly, other Ephedra extracts have been used to prepare various types of composite nanoparticles [187][188][189][190]. A bright future may be anticipated in front of Ephedra plant extracts in medicine, green chemistry, and the food industry.…”

Ephedra species are among the most popular herbs used in traditional medicine for a long time. The ancient Chinese medical book “Treatise on Febrile Diseases” refers to the classic traditional Chinese medicine prescription Ge Gen decoction, which consists of seven herbs, including an Ephedra species. Ephedra species are utilized all over the world to treat symptoms of the common cold and coughs, and to combat major human diseases, such as asthma, cancers, diabetes, cardiovascular and digestive disorders, and microbial infections. This study aimed at identifying specific Ephedra species used traditionally in Morocco for therapeutic purposes. The plant parts, their preparation process, and the treated pathologies were identified and analyzed. The results revealed five ethnobotanically important species of Ephedra: Ephedra alata Decne, Ephedra altissima Desf., Ephedra distachya L., Ephedra fragilis Desf., and Ephedra nebrodensis Tineo. These species are used traditionally in Morocco for treating people with diabetes, cancer, rheumatism, cold and asthma, hypertension, influenza virus infection, and respiratory ailments. In addition, they are occasionally used as calefacient agents, to regulate weight, or for capillary care. Few studies have underlined the antibacterial and antioxidant activities of some of these Moroccan Ephedra species, but little information is available regarding the natural products at the origin of the bioactivities. Further phytochemical investigations and clinical data are encouraged to better support the use of these plants.

As an additive for diesel engines, copper oxide nanoparticles (CuONPs) are thought to offer a lot of promise. In this work, an experimental investigation was conducted to ascertain the impact on a diesel engine of adding copper oxide (CuO) particles made from a Rubus fruticosus leaf extract product using a novel green synthesis approach. The presence and morphology of the CuO were analyzed by different characterization studies. Subsequently, was investigated the effects of the addition of CuONPs at two concentrations (15 and 20 ppm) on diesel engine performance, brake‐specific fuel consumption (BSFC), carbon monoxide (CO), hydrocarbon (HC), nitrogen oxide (NOX), and smoke emissions. From the experimental outcomes, the D100 + 20 ppm CuO blend shows a significant reduction in CO, HC, and smoke emissions by 58.19%, 25.15%, and 26.67%, respectively, when compared with standard diesel. Also, it was found that the D100 + 20 ppm CuO blend showed better engine performance with enhanced combustion characteristics. The experimental results provided a reduction of around 1.10% in BSFC. This study demonstrates how changes in fuel composition through the addition of nanoparticles to commonly used diesel fuel can provide meaningful improvements in engine performance and emissions.

Synthesis of nano‐particles using various greener approaches such as the use of plant extract, microbes, etc. is gaining a lot of popularity in the scientific community due to their advantages of being a cheaper protocol, reduction in the use of less hazardous chemicals, more environmentally benign method and good yield. It has been previously reported by many research groups that plant material provides reducing, capping as well as stabilizing agents and brings down biological and environmental risks in the green synthesis of nano‐particles. So it was thought worthwhile to synthesize copper oxide nano‐particles (CuO NPs) using some locally available medicinal plants. Rivina humilis L. plants which are available in our region of Vidarbha in Maharashtra State, India are considered to be the herbal plant for the treatment of respiratory‐related disorders mainly for asthma and cold by local tribal peoples. It has been found that it contains a variety of phytochemicals which can be employed for the synthesis of nanomaterials. With this aim it was thought worthwhile to present an efficient and greener approach for the synthesis of copper oxide nano‐particles using Rivina humilis L. (RH) whole plant extract. For characterization of bio‐synthesized CuO NPs, various spectral and analytical techniques such as UV‐Vis spectroscopy, FT‐IR, XRD, SEM, TEM, and EDS were employed. The newly synthesized CuO NPs were also tested for their potential biological activities against six different bacterial stains namely E. coli, P. aeruginosa, S. aureus, P. vulgaris, B. subtilis, and S. typhi using the well diffusion method. The antioxidant efficacy of the synthesized CuO NPs was undertaken through 1,1‐Diphenyl‐2‐picrylhydrazyl (DPPH) free radical scavenging activity. Their results have been presented and discussed in the present work.
