Medicinal and aromatic plants have been used by mankind since ancient times. This is primarily due to their healing effects associated with their specific secondary metabolites (some of which are also used as drugs in modern medicine), or their structures, served as a basis for the development of new effective synthetic drugs. One way to increase the production of these secondary metabolites is to use nanoparticles that act as elicitors. However, depending on the specific particle size, composition, concentration, and route of application, nanoparticles may have several other benefits on medicinal and aromatic plants (e.g., increased plant growth, improved photosynthesis, and overall performance). On the other hand, particularly at applications of high concentrations, they are able to damage plants mechanically, adversely affect morphological and biochemical characteristics of plants, and show cytotoxic and genotoxic effects. This paper provides a comprehensive overview of the beneficial and adverse effects of metal-, metalloid-, and carbon-based nanoparticles on the germination, growth, and biochemical characteristics of a wide range of medicinal and aromatic plants, including the corresponding mechanisms of action. The positive impact of nanopriming and application of nanosized fertilizers on medicinal and aromatic plants is emphasized. Special attention is paid to the effects of various nanoparticles on the production of valuable secondary metabolites in these plants cultivated in hydroponic systems, soil, hairy root, or in vitro cultures. The beneficial impact of nanoparticles on the alleviation of abiotic stresses in medicinal and aromatic plants is also discussed.

Medicinal And Aromatic Plants

Pegagan or Centella asiatica is one of the wild plants that has not experienced domestication. Countries in the Eastern have been concerned about conserving medicinal plants to the sustainability of medicinal and aromatic plants. The content of secondary metabolites in Centella asiatica has been known; those are several saponin compounds, including asiaticoside, madeccasoside, and asiatic acid. This study’s goal was to determine the content of secondary metabolites of asiaticoside, madeccasoside and asiatic acid at the top (leaves and petioles) and the bottom (roots and tendrils) with a harvest age of 12 weeks after planting (WAP). The planting site was in the lowlands of Deli Serdang, in which the measuring method used the HPLC tool. According to the results, Centella asiatica, harvested at 12 WAP, had a higher content of asiaticoside and madeccasoside in the roots and tendrils than in the leaves and petioles, while the content of asiatic acid was higher in the leaves and petioles than in the roots and tendrils. The bioactive compounds contained in Pegagan (Centella asiatica) are very efficacious for various diseases. Cultivation is carried out to avoid the loss of germplasm and genetic diversity in nature so that a balance in nature can be achieved.

AbstractSudan has a tremendous wealth flora due to its unique geographical location and diverse climate. Vast records of plants and plants’ secondary metabolites are reported to possess redox capacity and can be exploited for the biosynthesis of nanoparticles. Plant-mediated synthesis of silver nanoparticles is preferred due to their availability and their various metabolites. The present review explores the potentiality and diversity of biological activities of silver nanoparticles that originated from the combination of silver and phyto-constituents of mostly traditionally used Sudanese medicinal and aromatic plants. The green synthesis methods of silver nanoparticles mediated by more than 45 traditionally used medicinal plants are critically reviewed. In addition, parameters that affect the synthesis of plant-mediated silver nanoparticles, their characterization techniques and various biological activities are summarized and discussed. Thus, the study of green synthesis of silver nanoparticles and its applications can be extended to involve vast plant diversity of Sudan.

Medicinal plants, which are used as drugs to prevent diseases, maintain health or cure diseases, take place in areas such as nutrition, cosmetics, body care, incense or religious ceremonies, while aromatic plants are used in different industrial areas to give fragrance and taste are used. Flora of Turkey has a rich plant diversity. Secondary metabolites such as essential oils, alkaloids, glycosides, saponins etc. are the most basic products of the industry directly or indirectly. The vast majority of medicinal and aromatic plants rich in secondary metabolites exhibit strong biological activity (antioxidant, antibacterial, etc.). Therefore, these secondary metabolites are widely used in the pharmaceutical industry. The most common and practical use of secondary metabolites, which are also used as natural insecticides, is in the form of herbal tea. In recent years, the more side effects of synthetic origin substances, especially the resistance of organisms against synthetic drugs used as antimicrobials, have increased the importance of natural herbal resources and medicinal plants carrying these substances. Therefore, there is no doubt that the demand for secondary metabolites, which are natural products, will increase in the future. Flora of Turkey is an important source for natural products which will be developed newly.
