This may suggest that there may be synergistic effects between some plants exhibiting antifungal activity and commercial antifungal agents. Artemisia spp. (Figure 19.3A), Solanum aculeastrum (Figure 19.3B) and Myrtus communis (Figure 19.3C) are examples of medicinal plants reported to have anti-Aspergillus activity. Leaf extracts from Artemisia spp. have been reported to be effective against Aspergillus spp., with the ZOI ranging from 6.25–25 mm (Njoki, Okoth, and Wachira, 2017). Solanum aculeastrum also showed antifungal activity against A. flavus with the positive control, Apron Star (a class III blue active ingredient fungicide containing 20% thiamethoxam + 20% metalaxyl-M + 2% difenoconazole) having a larger ZOI (± 6 mm difference) (Njoki, Okoth, and Wachira, 2017).

Artemisia is a genus of small herbs and shrubs found in northern temperate regions and belongs to the family Asteraceae (295). Many species of Artemisia are known for their essential oils, mainly in the leaves which have strong aromas and bitter tastes. These volatile oils are constituted of diverse terpenoids and sesquiterpene lactones which have strong pharmacological activities (295). Artemisia is used as flavoring for food and as antiseptic, antiparasitic, antibacterial, antifungal, and more in the treatment of various infections. Here, only two Artemisia species: Artemisia annua and Artemisia herba-alba are examined as follows.

Artemisia is one of the largest heterogeneous genus of the plant species and an important member of the Asteraceae (Koul et al. 2018). It occurs well in temperate regions of the globe, such as in Asia, Africa, Australia, China, Europe, India, Iran, Japan, North America (Canada, Mexico, and the United States), and Turkey with around 500 known species (Koul et al. 2018, Watson et al. 2002, Liu et al. 2009). The origin of the name Artemisia can be traced back from the ancient Greek word “Artemis” which means goddess, and “absinthium” which relates to unenjoyable or without sweetness. Generally, Artemisia is known as “Worm wood”, as it is traditionally employed to treat intestinal worms. Other common names of the genus include “Mug word”, “Sagebrush”, or “Tarragon” (Obistioiu et al. 2014, Tajadod et al. 2012).

Recent studies on the biosynthesis of AgNPs have revealed that there was a significant shift in interest toward the use of medicinal flora for nanoparticle synthesis, where the green leaves of medicinal plants have the best capacity to reduce and stabilize AgNPs due to the abundance of reducing components (H+) [19,20]. Artemisia species are widely used to treat certain diseases, such as malaria, hepatitis, cancer, stomach ulcers and wound healing, due to their antibacterial, antifungal, and disinfectant properties [21]. They possess several compounds with insecticidal and anti-feeding activities against many insect pests, such as 3-methyl,3-phenyl-1,4-pentadiyne found in Artemisia monosperma essential oil [22]. Artemisia belongs to Family Asteraceae (Compositae). There are ~250 species of Artemisia worldwide, found in Europe, Asia, Africa and North America [23]. However, few studies have dealt with nanoparticle synthesis from Artemisia species and its cytotoxic and apoptosis effects [19]. Vijayakumar et al. [24], Basavegowda et al. [25] and Mousavi et al. [19] have synthesized nanoparticles from three different species of Artemisia and investigated their antimicrobial activity. Aziz et al. [26] demonstrated that AgNPs synthesized from Artemisia herba-alba showed high larvicidal toxicity against mosquito vectors.
Characterization, antibacterial, total antioxidant, scavenging, reducing power and ion chelating activities of green synthesized silver, copper and titanium dioxide nanoparticles using Artemisia haussknechtii leaf extract
Published in Artificial Cells, Nanomedicine, and Biotechnology, 2018
In green synthesis approaches of metal NPs unlike chemical and physical method, it was not used toxic reducing agents or expensive solvents. Therefore, NPs green synthesis methods have eco-friendly and low cost advantages compared to conventional methods. In this way, it can be applied plants, algae, bacteria and fungi as reducing and stabilizing precursors [7]. Among these organisms, plants have advantages of high availability, biocompatibility and biodegradability [8]. Artemisia L. belongs to the large family Asteraceae (Compositae) with approximately 20,000 species in 1000 genera. There are over 500 species in Artemisia genus which are located abundantly in Asia (with 35 species in Iran), Europe and North America [9]. Species of this genus are used frequently as medicinal plant for the against of malaria, inflammation, pyrexia, cancer, hepatitis and infectious disease [10]. These characteristics are resulted from constituents of essential oils such as piperitone, camphor, β-ylangene, β-elemene, and sapathulenol [9]. Accordingly, among this genus, we used A. haussknechtii as endemic species of Iran especially Kermanshah province for green synthesis of NPs [9,11].

Several plants, such as Artemisia marschalliana Sprengel, Carica papaya peel, Pongamia pinnata seed, Heterotheca inuloides and Borago officinalis, have been used to synthesize AgNPs [24–28]. In this study, the extract of A. oliveriana, a plant species native to Iran, was used for the first time to synthesize AgNPs. In general, there are over 20,000 species of Artemisia around the world, and several of these Artemisia species are used for therapeutic purposes, such as sedative factors, cough relief and anti-hypersensitivity agents, as well as for the treatment of malaria. Out of the total 20,000 Artemisia species, 34 species have been found in Iran. Artemisia oliveriana belongs to the Asteraceae family and this plant has a high content of flavonoids and terpenoids, as well as that of a chemical known as tannin [29]. Overall, the aim of this study was the green synthesis of AgNPs using A. oliveriana extract and to evaluate their biological effects.
