synthesis of silver nanoparticle using portulaca oleracea l. extracts
Authors
abstract
objective(s): to evaluate the influences of aqueous extracts of plant parts (stem, leaves, and root) of portulaca oleracea l. on bioformation of silver nanoparticles (agnps).materials and methods: synthesis of silver nanoparticles by different plant part extracts of portulaca oleracea l. was carried out and formation of nanoparticles were confirmed and evaluated using uv-visible spectroscopy and afm.results:the plant extracts exposed with silver nitrate showed gradual change in color of the extract from yellow to dark brown. different silver nanoperticles were formed using extracts of different plant parts. conclusion: it seems that the plant parts differ in their ability to act as a reducing and capping agent.

Portulaca oleracea L., belonging to the Portulacaceae family, is commonly known as purslane in English and Ma-Chi-Xian in Chinese. It is a warm-climate, herbaceous succulent annual plant with a cosmopolitan distribution. It is eaten extensively as a potherb and added in soups and salads around the Mediterranean and tropical Asian countries and has been used as a folk medicine in many countries....

The flavonoid apigenin was isolated from aerial part of P. oleracea L. The dried sample of plant was powdered and subjected to soxhlet extractor by adding 80 mL of ethanol : water (70 : 30). The extract was centrifuged at 11000 rpm for 30 min; supernatant was taken for further use. The fraction was concentrated and subjected to PTLC. The R f value of isolated apigenin was calculated (0.82). Pur...

A new tricyclic alkaloid named portulacatone (1), i.e., 5,6-dihydro-8,9-dihydroxy-11H-pyrrolo[2,1b] [3]benzazepin-11-one, together with eight known compounds, methyl 4-hydroxyphenylacetate (2), phydroxybenzaldehyde (3), vanillin (4), protocatechualdehyde (5), p-hydroxybenzoic acid (6), iseluxine (7), oleracein E (8), and (þ)-(R)-feruloyl malate (9) were isolated from aerial parts of Portulaca o...
full textEvaluation of antioxidant potential and reduction capacity of some plant extracts in silver nanoparticle synthesis
The green synthesis of metallic nanoparticles is an active research area in nanotechnology. In the present study, antioxidant potential, total reducing capacity and silver nanoparticles (Ag NPs) synthetic potential of methanolic leaf extracts of seven plant species were evaluated and compared. Antioxidant capacity, expressed as µmol Trolox equivalents g-1 DW (µmol TE g-1 DW), ranged from 116.0 ...
full textNeuroprotective effect of Portulaca oleracea extracts against 6-hydroxydopamine-induced lesion of dopaminergic neurons.
The Portulaca oleracea L. (Portulacaceae) is a cosmopolitan species with a wide range of biological activities, including antioxidant and neuroprotective actions. We investigated the effects of P. oleracea extracts in a 6-hydroxydopamine rat model of Parkinson's disease, a debilitating disorder without effective treatments. Chemical profiles of aqueous and ethanolic extracts of whole plant were...
