Employment of Cassia angustifolia leaf extract for zinc nanoparticles fabrication and their antibacterial and cytotoxicity

الملخص EN

The plant Cassia angustifolia belongs to Saudi Arabia, which is one of the native places and now cultured throughout the global countries.

medical care in the arab world is an essential outlet for medicinal plants, both because they are crucial elements for prophetic medicine and due to their lengthy background in the middle east.

C.angustifolia is one of the medicinal plants used in the Saudi Arabia.

the usage of plant extracts for synthesizing nanoparticles is conducive to other biological material, since it avoids the lengthy phase of cell culture maintenance.

silver nanoparticles attract further attention due to their strong conductivity, stability and antimicrobial activity across different metal nanoparticles.

the present study was designed in the Saudi C.

angustifolia leaves with the zinc synthesis of nanoparticles and its antibacterial ability.

the plant extracts of C.

angustifolia was used for synthesis of zinc nanoparticles, antimicrobial activities against bacterial strains have been tested along with transmission electron microscope (TEM), UV spectroscopy and antimicrobial activities have been conducted.

this study showed that silver ions may be transferred from the plant extract to silver nanoparticles.

AgNPs biogenic capacity to antibacterial with lovo cell with IC50 ranged from 33.5 ± 0.2 lg/mL demonstrated strong antibacterial capacity to antibody.

The overall absorption value for the extract was between 420 and 440 nm and the color transition to green was the plasma absorption of the AgNPs.

TEM results was showed in 200,000 magnification.

the uniqueness of the current study is that Cassia angustifolia leaf extract from Saudi Arabia was used to prepare the metallic nanoparticles.

additionally, ZnCl2 may also be used as nanoparticles of mineral salt and zinc, which, since their application has been confirmed, are antimicrobial.
