Abstract

Plants are a source of chemical compounds such as alkaloids, steroids, essential and fixed oils, which can be used against many diseases. Here, we evaluated the aqueous and solvent extract of four plants (Syzygium aromaticum, Elettaria cardamomum, Nigella sativa, Capsicum annuum), and assessed their antimicrobial activity against Escherichia coli using will diffusion method after 24 h. The oil crude extract of S. aromaticum showed the highest antimicrobial activity, while the oil crude extract of C. annuum showed the lowest activity. Our study revealed that the utilization of aqueous and solvent extract of some traditional plants against E. coli would be an effective way in the management of some environmental bacterial diseases.

Highlights

For a long time, human used plant resources in many applications, such as antibiotics, perfumes, insecticides, food and cure many diseases [1, 2]
Soxhlation Soxhlation method was done according to [12] with some modifications. 25 g of N. sativa and C. annuum were extracted in a soxhlet apparatus using ethanol as a solvent (150 ml) for 6 hours
Plant extraction In this study, S. aromaticum and E. cardamomum were extracted using hydrodistillation and N. sativa and C. annuum were extracted in a soxhlet

Summary

Introduction

Human used plant resources in many applications, such as antibiotics, perfumes, insecticides, food and cure many diseases [1, 2] These plants contain many active compounds which called sometimes crude extract, like essential oils, phenols, and flavonoids which found in many parts in the plant such as leaves, flowers, bark, seeds, fruits, and roots [2]. This crude extract can be separated from the plant using extraction methods, which are one of the easier ways [3]. This disease such as cardiovascular, diabetes, Alzheimer's, cancer [5], besides, the antimicrobial impacts were studied by many researchers [6]
