Bioactivity-guided Study of Passiflora caerulea L. Leaf Extracts
Passiflora species were known by their anticonvulsant, anxiolytic and sedative activities. The aim of this study was to investigate the chemical composition of the most active leaf extract of Passiflora caerulea L. grown in Egypt. The ethanolic extract of the leaves exhibited higher activity than aqueous extract as anticonvulsant (63% potency relative to carbamazepine), analgesic (70% potency r...

متن کاملMolecular genetic control of leaf lifespan in plants - A review
Leaf senescence constitutes the last stage of leaf development in plants and proceeds through a highly regulated program in order to redistribution of micro- and macro-nutrients from the senescing leaves to the developing/growing plant organs. Initiation and progression of leaf senescence is accompanied by massive sequential alterations at various levels of leaf biology including leaf morpholog...
متن کاملAchyranthes Aspera Leaf Extracts Inhibited Fungal Growth
The aim of the study was investigate antifungal activity of the various leaves extracs of Achyranthes aspera Linn.The aqueous,ethanol and methanol leaves extracts of Achyranthes aspera Linn. (Family:Amaranthaceae) were evaluated for antifungal activity against clinically important fungal spp viz. Candida albicans (MTCC 227), C.tropicalis (MTCC 750), C.krusei (ATCC 6258), C.kefyr (ATCC 4235), C....
متن کاملMolecular aspects of leaf senescence.
Senescence is the last stage of leaf development and one type of programmed cell death that occurs in plants. The relationships among senescence programs that are induced by a variety of factors have been addressed at a molecular level in recent studies. Furthermore, an overlap between the pathogen-response and senescence programs is beginning to be characterized. The complexity of the senescen...
