Eragrostis plana (Nees) is an allelopathic plant with invasive potential in South American pastures. To isolate and identify phytotoxic compounds from leaves and roots of E. plana, a bioassay-directed isolation of the bioactive constituents was performed. This is the first report on a new diterpene carbon skeleton, neocassane, and of three new neocassane diterpenes, neocassa-1,12(13),15-triene-3,14-dione, 1; 19-norneocassa-1,12(13),15-triene-3,14-dione, 2; and 14-hydroxyneocassa-1,12(17),15-triene-3-one, 3, identified from the roots. Compounds 1, 2, and 3 inhibited the growth of duckweed by 50% at concentrations of 109 ± 28, 200 ± 37, and 59 ± 15 μM, respectively. Compound 2 was fungicidal to Colletotrichum fragariae, Colletotrichum acutatum, and Colletotrichum gloeosporioides. The compounds identified here could explain the allelopathy of E. plana. The description of the newly discovered compounds, besides contributing to the chemical characterization of the species, may be the first step in the study of the potential of these compounds as bioherbicides.

“…The resulting extracts were filtered and concentrated on a rotary evaporator under vacuum. The extracts were suspended in water containing 1% dimethyl sulfoxide (DMSO) to obtain a final 100 mg/mL concentration and then filtered through a sterilizing membrane with 0.22 μm [51].…”

Antioxidant, Antibacterial, and Antifungal Activities of the Ethanolic Extract Obtained from Berberis vulgaris Roots and Leaves

et al. 2022

This work assessed the phenolic and flavonoid components and their antioxidant, antifungal, and antibacterial effects in the ethanolic extract of barberry leaf and roots. The antibactericidal activity of root and leaf extracts against pathogenic bacteria was tested using agar diffusion and microdilution broth production for the lowest inhibitory concentration (MIC). Berberis vulgaris root and leaf extracts inhibited Staphylococcus aureus ATCC9973, Escherichia coli HB101, Staphylococcus enteritis, and Escherichia coli Cip812. The disc assay technique was used to assess the bactericidal activity of the extracts versus both pathogenic Gram-positive and Gram-negative strains. Hydro alcoholic extract was more effective against bacterial than fungal strains. The results showed that Berberis vulgaris leaf and roots extract had similar antifungal activities. Berberis vulgaris root extract inhibited the mycelial growth of Penicillium verrucosum, Fusarium proliferatum, Aspergillus ochraceous, Aspergillus niger, and Aspergillus flavus. Berberis vulgaris root extract has excellent antioxidant, antibacterial, and antifungal effects. Berberis vulgaris exhibited antimicrobial activity in vitro, and MIC showed that Berberis vulgaris parts efficiently affected pathogens in vitro. In conclusion, both Berberis vulgaris roots and leaves have considerable antibacterial activity and can be used as a source of antibacterial, antioxidant, and bioactive compounds to benefit human health.
