The mechanisms responsible for the origin, maintenance and evolution of plant secondary metabolite diversity remain largely unknown. Decades of phenotypic studies suggest hybridization as a key player in generating chemical diversity in plants. Knowledge of the genetic architecture and selective constraints of phytochemical traits is key to understanding the effects of hybridization on plant ch...

The wild mint "Mentha longifolia (L.) Hudson subsp. noeana (Briq.) Briq." is an important medicinal plant which contains several worthy components like: menthone, pulegone, pipertenon, menthol, thymol, and carvone in its essential oil. This plant grows extensively in center of Asia including Iran. Because of so worthy components and its big role in traditional and modern medicine, the wild mint...

Natural products from medicinal plants, either as pure phytoconstituents or as standardized extracts, provide unlimited opportunities for new drug leads because of the unmatched availability of chemical diversity. In the present investigation include the extraction, isolation and characterization of active compounds from Syzygium alternifolium (Wight) Walp. Isolated phytoconstituents were forwa...

Zephyranthes is a genus of bulbous perennials belonging to family Amaryllidaceae. This family is one of the top 20 most widely used plant families well known for its ornamental value. The plants of this family are used by native peoples of different countries for treating various diseases. The genus Zephyranthes is one amongst 75 genera under this family [1,2]. It consists of about 90 species a...

Sensory and chemical analyses were performed on accessions of rocket (Eruca sativa) to determine phytochemical influences on sensory attributes. A trained panel was used to evaluate leaves, and chemical data were obtained for polyatomic ions, amino acids, sugars and organic acids. These chemical data (and data of glucosinolates, flavonols and headspace volatiles previously reported) were used i...

Biodiversity in ecosystems is crucial providing ecosystem services and their stability resilience. However, most studies supporting the benefits of biodiversity crop health were studied at cultivar scale, generally without specifying resistance mechanisms involved crops to pests. Thus, it unclear if phytochemical diversity one those whether patterns processes which can be replicated or adapted ...

In this paper, we argue that the metaphor form of a comparison (i.e., a topic-vehicle pair) is preferred over, and more comprehensible than, the simile form when the interpretive diversity for that comparison is high. Interpretive diversity refers to the richness of the figurative meaning of a comparison; it is high to the extent that more features or properties are related to the figurative me...
