Summary

Medicinal natural products have a preponderant part in the drug discovery, and due to the arising of new challenges for microorganism control including virus, bacterial, fungi or protozoal the study of bioactive plants takes more importance in these days. Moreover, with the constant discovery of new therapeutic target for human health the bioactive metabolites are an inspiration for new drugs development. Also, the interaction between plants with insects, fungi or between plants are new topics possible to understand from their volatile metabolites.

 

The scope of the Special Issue is highlighting the role of plants in health going by their relevance in folk medicine and the study of their essential oils and metabolites by qualitative, quantitative and biochemical analysis.

 

Potential subjects for this topic include

- Extraction methods of plants

- Quantification of secondary metabolites  

- Structure analysis of compounds isolated from plants

- Purification methods of secondary metabolites

- Biotransformation of natural compounds

- Antimicrobial activity of total extracts

- Enzymatic assays against relevant proteins

- Essential oils and their properties

- Biological activity of metabolites in general

Plant-insect interaction


Keywords

natural products, isolation, structure determination, biological activity, plant defense, biological control

    Abstract In the search for new alternatives to control tropical fungal pathogens, the ethanol extracts (EEs) from Acalypha gaumeri (Euphorbiaceae) roots showed antifungal properties against several tropical fungal phytopathogens. A. gaumeri is classified as endemic to the Yucatan Peninsula, Mexico, an area with distinct rainy, drought and northern seasons. The present study evaluated the antifungal activity of three wild populations of A. gaumeri collected quarterly in different seasons during one year against Alternaria chrysanthemi, Colletotrichum gloeosporioides, and Pseudocercospora fijiensis and explored their ex-situ propagation. The highest activity was shown by the EE from the Tinum wild population during the rainy season against A. chrysanthemi,… More >

    Abstract The use of conventional herbal medicines is a rapidly expanding phenomenon in developed nations. For instance, 30%–50% of all drug use in China is attributed to traditional herbal preparations. Current study evaluated the antioxidant (DPPH, FRAP), total phenolic and flavonoid content, antibacterial activity, and DNA damage protective potential of aqueous and methanolic extracts obtained from the aerial parts and roots of Cymbocarpum wiedemannii Boiss., an endemic plant in Turkey. In antioxidant analyses, the methanolic extract of the aerial parts showed the highest %DPPH (73.38) and IC50 (3.46 mg/mL) values. The FRAP analysis revealed the highest iron-reducing… More >
