Abstract

The aim of this study is to investigate in vitro antioxidant and antibacterial activities of the aqueous and hydroethanolic extracts for aerial parts of Herniaria hirsuta. Extracts were screened for their possible antioxidant activities by three tests: DPPH free radical-scavenging, reducing power, and molybdenum systems. The screening of antibacterial activity of extracts was individually evaluated against sixteen bacteria species using a disc diffusion method. Flavonoids, total phenols, and tannins content were performed for both extracts. It shows higher content in the hydroethanolic extract. The hydroethanolic extract showed a significant antioxidant activity for the three methods studies to the aqueous extract, but nonsignificant results compared to the reference (BHT). However, both extracts have negative effect on the strains studies for the antibacterial activity.

Highlights

The genus of Herniaria contains several species which are widely distributed in Europe, Asia, and North Africa
Herniarin and umbelliferon were identified as coumarins, quercetin, and isorhamnetin derivatives as flavonoids being present in Herniaria species [13,14,15,16,17]
The extraction of H. hirsuta aerial parts showed a higher yield for the hydroethanolic extract with a value of 31.20%, followed by the aqueous extract with a yield of 28.73%

Summary

Introduction

The genus of Herniaria contains several species which are widely distributed in Europe, Asia, and North Africa. Some phytochemical research on these species revealed the presence of saponins, flavonoids, and coumarins, while H. fontanesii was reported to contain saponins A–D [6,7,8], which are bidesmosidic triterpenoid saponins, two monodesmosidic derivatives of medicagenic acid. H. glabra contained several mono- and bidesmosidic medicagenic acid derivatives, named Herniaria saponins [1,2,3,4,5,6,7, 9,10,11,12]. Herniarin and umbelliferon were identified as coumarins, quercetin, and isorhamnetin derivatives as flavonoids being present in Herniaria species [13,14,15,16,17]
