Phytotoxic substances released from plants are considered eco-friendly alternatives for controlling weeds in agricultural production. In this study, the leaves of Afzelia xylocarpa (Kurz) Craib. were investigated biological activity, and their active determined. Extracts A. leaf exhibited concentration-dependent phytotoxic activity against seedling length Lepidium sativum L., Medicago sativa Ph...
Reacting active species induced oxidative damage of cellular tissue cause to many human diseases like cancer, cardiovascular disease, nephropathy and aging. Naturally occurring antioxidant supplements from plants are vital to counter the oxidative damage in cells. Recently, attention has focused on phytochemicals as new sources of natural antioxidants. Therefore, the main objective of the prese...
The chemical composition of the essential oils of Melaleuca armillaris Sm., Melaleuca styphelioides Sm. and Melaleuca acuminata F. Muell., collected in Tunisia, was studied by means of GC and GC-MS analysis. In all, 46 compounds were identified, 38 for M. armillaris, 20 for M. acuminata and eight for M. styphelioides, respectively. The presence of a sesquiterpenic fraction (52.2%) characterized...
Selective foraging by granivores can have important consequences for the structure and composition of plant communities, and potentially severe consequences for rare plant species. To understand how granivore foraging behavior affects common and rare plant species, diet selection should be viewed relative to the availability of alternative seed options, and with consideration of the individual ...
The flowering process in plants proceeds through the induction of an inflorescence meristem triggered by several pathways. Many of the genes associated with these pathways encode transcription factors of the MADS domain family. The MADS-domain transcription factor APETALA1 (AP1) is a key regulator of flower development. The first step to understand the molecular mechanisms under the function of...
Seven new rare sinapoyl acylated flavonoid glycosides, apetalumosides A1 (1), B8 (2), B9 (3), B10 (4), B11 (5), B12 (6), and C1 (7) were isolated from the seeds of Lepidium apetalum Willd. Their structures were elucidated by chemical and spectroscopic methods.
