Abstract

To synthesized and characterized green iron nanoparticles extracted from plants. Synthesis of iron bio-nanoparticles was done by using ALoe vera gel water extract as un-reducing agent. Characterization of Iron nanoparticles was performed using UV, XRD, and FTIR. The diameter of iron nanoparticles was about 52 nm.  The effect of the exposure of Aloe vera seeds to iron nanoparticles on germination of Lepidium sativum has been studied. Seeds were exposed to green iron nanoparticles. Germination percentage and root shoot length were calculated. The results showed a reduction in germination percentage on exposure to 1000ppm of green nanoparticles while maximum germination percentage was on application of iron nanoparticles at 500ppm. Root and shoot growth was enhanced under iron nanoparticles application while reduction in root and shoot length was observed on exposure to 1000ppm of nanoparticles and Fe.

Introduction 

Synthesis Green iron nanoparticles, instead of using chemical reducing agent such as sodium borohydride which is flammable and corrosive (Khenfouch et al., 2016). Now a day’s researcher used extracts of plant part in preparing nano particles (Nyangiwe et al., 2015).

These tiny products also have a large surface area to volume ratio, which is their most important feature responsible for the widespread use of nanomaterials in mechanics, optics, electronics, biotechnology, microbiology, environmental remediation, medicine, numerous engineering fields and material science (Sone et al., 2017). Different protocols have been designed for the production of metallic nanoparticles. Chemical physical, electrical and Biological (Sundus et al., 2013).

The coating is used to stabilize the particles in colloidal form, to prevent them from degradation and to minimize the toxicity. Generally, magnetite and maghemite are the two important forms of iron oxide, which are used as the magnetic materials for biomedical applications (Sundus et al., 2017).

Agglomeration of magnetic nanoparticles is inevitable, because of their Vander Waals attractive forces between the tiny particles. Magnetite (Fe3O4) nanoparticles are chemically stable and non carcinogenic and has high saturation value (92emu/g) compared to the maghemite bulk material.

The production of iron nanomaterials, such as metallic iron and oxide of iron via a more convenient greener route, is a great step forward in the development of nanomaterials. This review highlights the significance of biogenic approaches and the role of biocompatible green materials in technological and economically feasible process and practices (Sundus 2018).

The main objective of the current study is to preparation green iron nano particles by using Aloe vera gel and characterize it by absorption spectrophotometer (UV- VIS), X-ray diffraction (XRD), and scanning electron microscope (FTIR).

Studying Several indexes during the germination seed of Lepidium sativum such as root length, shoot length, fresh weight and germination ratio. To the best of our knowledge, it is the first reports focused on the effect of Lepidium sativum seeds germinating after exposing to Aloe vera iron nano particles nanoparitcles with different morphologies.

Abstract

Moringa oleifera is a common plant and known for various medicinal properties. The research work was conducted to investigate the anticytotoxic and antioxidant activity of dried flower powder extract of leaf Moringa oleifera. The ethanol extracts from flower of moringa plants contain severalphytochemicals such asalkaloids,amino acids, quinones, cardiac glycosides, flavonoids, phenols, saponins, tannins, terpenoids, coumarins and triterpenoids.The antioxidant activities of different concentrations of ethanol extracts of the leaves were determined by the three assay techniques i.e., DPPH radical scavenging assay, Ferric reducing ability power (FRAP). The type of chemical bonds is identified through FTIR analysis. The results obtained in the present study indicate that the leaves of Moringa oleifera are a potential source of anticytotoxic and antioxidants.

Introduction

Moringa oleifera (MO) grows owing to its nutrientrich seeds, edible leaves and flowers that can be used as food, medication, cosmetic oil, or livestock feed. The height varies between 5 to 10 meters. Different experiments have been demonstrated positive effects on health. MO is also used in developing countries as a source of fruits, medicinal plants, and edible oil. It is an essential nutrient- rich vegetative plant and is commonly considered as a versatile food that can be eaten in all sections (Bharali et al., 2003). Moringa claimed as a nutrient-rich due to its anti-ulcer, antidiabetic, hepatoprotective, diuretic and cholesterol lowering capacity. It has also been used in skin and hair care products (Brown et al., 1998). Moringa oleifera Lam., also known as the drumstick tree.’ It is mostly found in areas having warm and dry and moist. The most important bioactive compounds of plants are alkaloids, flavonoids, tannins, and phenolic compounds (Caceres et al., 1992). Different parts of this plan contain a profile of important minerals, and a good source of protein, vitamin, a carotene, amino acids and various phenolics. In the tropics, it is used as forage for livestock, and in many countries, it is used as a micronutrient powder to treat various ailments (Clarke Hans Thacher, 2007). Moringa oleifera has several medicinal properties and has potentiality to cure many diseases (Donli et al., 2003). It is used to treat diseases such as diabetes, heart disease, anaemia, arthritis, respiratory problems, skin, liver problems, paralysis, sterility, rheumatism, digestive disorders and many more (Eilert et al., 1981). The anticancer result of Moringa has been tested for its chemo-protective properties and has been shown to prevent the development of various human cancer cells (Fahey, 2005). M. oleifera has several bioactive compounds with antitumor activity.
