AB  - Several scientific studies have been proving the bioactive effects of many aromatic and medicinal plants associated with the presence of a high number of bioactive compounds, namely phenolic compounds. The antioxidant, anti-inflammatory, and antimicrobial capacities of these molecules have aroused high interest in some industrial sectors, including food, pharmaceuticals, and cosmetics. This work aimed to determine the phenolic profiles of the infusions and hydroethanolic extracts of five plants (Carpobrotus edulis, Genista tridentata, Verbascum sinuatum, Cytisus multiflorus, and Calluna vulgaris) that have been employed in many traditional preparations. In addition, the antioxidant, antimicrobial, anti-inflammatory, and anti-tumoral activity of each different preparation was evaluated using in vitro assays. The HPLC-DAD-ESI/MS profile revealed the presence of eighty phenolic compounds, belonging to seven different families of compounds. Regarding antioxidant properties, the hydroethanolic extract of C. edulis showed a potent effect in the TBARS assay (IC50 = 1.20 µg/mL), while G. tridentata hydroethanolic extract achieved better results in the OxHLIA test (IC50 = 76 µg/mL). For cytotoxic and anti-inflammatory results, V. sinuatum infusions stood out significantly, with GI50 = 59.1-92.1 µg/mL and IC50 = 121.1 µg/mL, respectively. Finally, C. edulis hydroethanolic extract displayed the most relevant antibacterial activity, showing MBC values of 0.25-1 mg/mL, while G. tridentata hydroethanolic extract exerted the greatest antifungal effects (MFC of 0.5-1 mg/mL). The results of this study deepen the knowledge of the phenolic profiles and also provide evidence on the bioactive properties of the species selected, which could be considered highly valuable options for research and application in several sectors, namely food, cosmetics, and pharmaceuticals.

AB  - Plant extracts have potential as food additives. In this sense, this work aimed to study the bioactivities of plant extracts and their ability as health-promoting additives.

Lavender, lemon balm, basil, tarragon, sage, and spearmint dry aerial parts were mechanically ground. Three extraction methods were tested: infusion and decoction, using distilled water as solvent and a sample/solvent ratio of 1:100; and hydroethanolic extraction, using ethanol 80% (v/v) as solvent and a sample/solvent ratio of 1:60.

The extracts obtained were evaluated for their antimicrobial and antifungal activities, by a microdilution method. The antioxidant activity was evaluated through the lipid peroxidation inhibition assay (TBARS) and the oxidative haemolysis inhibition assay (OxHLIA). Cytotoxic activity was evaluated in tumour and non-tumour cell lines using the sulforhodamine B method, and anti-inflammatory activity in lipopolysaccharide-activated RAW 264.7 macrophages by the ability to inhibit NO production.

The results showed that all extracts exhibited antimicrobial activity against six pathogens tested (MIC ≤ 2 mg/mL) and antifungal capacity against, at least, five fungi (MFC ≤ 1 mg/mL).

In the TBARS evaluation, lemon balm infusion (125±2 μg/mL) and hydroethanolic extracts of spearmint (132±5 μg/mL) and lavender (177±4 μg/mL) presented the highest activities. In the OxHLIA assay, sage decoction (8.9±0.4 μg/mL) and hydroethanolic extracts of spearmint (12.5±0.2 μg/mL) and lemon balm (13.5±0.4 μg/mL) showed the best capacities to inhibit oxidative haemolysis.

Regarding the anti-inflammatory activity, only the extracts of spearmint and basil, and the decoction and hydroethanolic extracts of tarragon, showed promising results (GI50<89 μg/mL). As for the cytotoxicity assay, most extracts (except those of tarragon and the infusion and decoction of basil) revealed anti-proliferative capacity in the AGS, CaCo, and HeLa tumour lines (GI50<400 μg/mL).

These outcomes provide insight on the bioactivity of numerous herbal extracts, emphasising their value as food additives to prevent spoilage and deliver beneficial health effects.
