Cell growth inhibitory potential of Craterellus cornucopioides (L.) Pers. together with antioxidant and antimicrobial properties

Craterellus cornucopioides (L.) Pers which is also known as trumpet of death or horn of plenty, is a wild edible macrofungus. This study was conducted to elucidate the potential health beneficial properties of C. cornucopioides. Bioactive ingredients (phenolics, flavonoids, β-carotene and lycopene) and DPPH radical scavenging activities were determined. Additionally, cell growth inhibitory effects on HepG2 cells together with some bacteria were evaluated. Accordingly, water and methanol extracts contains 37.71±1.42 μg/mg and 13.78±1.60 μg/mg phenolic contents, respectively. Similarly, methanolic extracts have higher β-caroten and lycopene content as compared to aqueous extracts. In parallel with these antioxidants, methanolic extracts have also higher DPPH scavenging activity (IC50: 5.26±0.67 mg/ml). Besides, water extracts have higher flavonoid contents (2.13±0.06 μg/mg) then the methanolic extracts. C. cornucopioides has also an important cell growth inhibitory effects on HepG2 cell (IC50: 18.41±1.10 mg/ml for aqueous extracts and IC50: 3.14±1.07 mg/ml for methanolic extracts). Moreover, both extracts were effective on six different bacteria tested. As a result, this study indicates that C. cornucopioides could reduce the cellular oxidative stress because of its high antioxidant ingredients, inhibit the growth of pathogen microrganisms and have some degree of cell growth inhibitory potential at least to the HepG2 cells.
