Introduction

Usage of natural antioxidants from plants and the other natural sources has been among the most important ingredients in food and pharmaceutical industries. Having the ability to defend against the reactive oxygen stress (ROS),Natural antioxidants can protect the human heath from a lot of diseaseses, they are Generally Recognized As Safe (GRAS) and the have less toxicity in industrial products compared to the artificial synthetic ones. Zingiberaceae is a family in the plant kingdom that has been highly investigated due to its versatile nature and high medicinal impact. The largest genus of Zingiberaceae family is Alpinia.

Introduction

Usage of natural antioxidants from plants and the other natural sources has been among the most important ingredients in food and pharmaceutical industries. Having the ability to defend against the reactive oxygen stress (ROS),Natural antioxidants can protect the human heath from a lot of diseaseses, they are Generally Recognized As Safe (GRAS) and the have less toxicity in industrial products compared to the artificial synthetic ones. Zingiberaceae is a family in the plant kingdom that has been highly investigated due to its versatile nature and high medicinal impact. The largest genus of Zingiberaceae family is Alpinia.
In this paper , the antibacterial efficacy of hexane, ethyl acetate and methanol isolated from Alpinia nigra seeds against diverse range of pathogenic bacteria was investigated. Field emission scanning electron microscopy (FESEM) was used for observing the altering of the morphology of the bacteria. Authors also determined the antioxidant potential by the scavenging effect on 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals of all the tested seed extracts.

Materials and methods

Different techniques were performed as follows: Preparation of organic extracts, Determination of DPPH radical scavenging activity, Fourier transform infrared radiation (FTIR) and nuclear magnetic resonance (NMR) analysis, Determination of total soluble phenolics (TSP), Antibacterial activity such as determination of antimicrobial activity by agarhole method,
