“…portoricensis leaves contain saponins, tannins, flavonoids and glycosides [70]. Numerous pharmacological activities have been reported, including anti asthmatic [71]; hypolipidaemic, erythropoietic [72], anti-sickling [73], anticonvulsant [74,75] anthelmintic [70], antimicrobial as well as traditional management of sickle cell anaemia and prostate cancer in Africa [71], and analgesic [76,77].…”

A study on host specificity and phytochemical constituents of leaves of mistletoe and parasitized twigs of seven host trees/shrubs was conducted in University of Benin, Benin City, Nigeria. Plant height and location were measured with Nikon Laser Rangefinder (Forestry 550) and GPS respectively while occurrence and count of mistletoe on host plants was largely anecdotal/visual. Phytochemical analyses were conducted at Faculty of Agriculture Science/Soil Laboratory, University of Benin, Benin City, Nigeria while data were subjected to One-way Analysis of Variance and means separated using Duncan Multiple Range Test (p=0.05). Results revealed mistletoe were largely generalists, and contained more phytochemicals than host plants. Tapinanthus ogowensis from Moringa oleifera was richest in alkaloid; Phragmanthera nigritana on Citrus sinensis, Tapinanthus ogowensis on Moringa oleifera and Phragmanthera capitata on Calliandra portoricensis recorded highest phenol content and differences among them were not significant (p<0.05). Phragmanthera capitata on Spondias mombin had significantly higher tannins than other mistletoe and host plants (p<0.05). P. capitata on S. mombin recorded best for saponin and flavonoid while P. capitata on Psidium guajava, Loranthus micranthus on Persia americana and P. capitata on C. portoricensis recorded more anthraquinone and were not significantly different from each other p<0.05. While the marked variation in phytochemicals in leaves of mistletoe and twigs of host plants is noteworthy; the study sufficiently established that ecological idiosyncrasies, time/season and varied environmental phenomena strongly influence incidence and/or buildup of secondary metabolites. The foregoing should serve as benchmark in selection and/or use of mistletoe for resolving infirmities.

In recent times, plant-mediated synthesis of nanoparticles has garnered wide interest owing to its inherent features such as rapidity, simplicity, eco-friendliness and cheaper costs. For the first time, silver nanoparticles were successfully synthesized using Calliandra haematocephala leaf extract in the current investigation. The as-formed silver nanoparticles were characterized by UV-Vis spectrophotometer and the characteristic surface plasmon resonance peak was identified to be 414 nm. The morphology of the silver nanoparticles was characterized by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) was used to detect the presence of elemental silver. X-ray diffraction (XRD) was employed to ascertain the crystalline nature and purity of the silver nanoparticles which implied the presence of (1 1 1) and (2 2 0) lattice planes of the face centered cubic (fcc) structure of metallic silver. Fourier transform infrared spectroscopy (FTIR) was used to key out the specific functional groups responsible for the reduction of silver nitrate to form silver nanoparticles and the capping agents present in the leaf extract. The stability of the silver nanoparticles was analyzed by zeta potential measurements. A negative zeta potential value of À17.2 mV proved the stability of the silver nanoparticles. The antibacterial activity against Escherichia coli -pathogenic bacteria -and the capacity to detect hydrogen peroxide by the silver nanoparticles were demonstrated which would find applications in the development of new antibacterial drugs and new biosensors to detect the presence of hydrogen peroxide in various samples respectively. ª 2015 The Authors.
