For many years, natural bioactives have been used to treat, cure, and prevent diseases. Crude extracts from fruit seeds have been demonstrated to possess a range of advantageous biological properties, including anti-inflammatory, antioxidant, and anti-tumorous effects. In this study, the seeds of Garden Cress (Lepidium sativum, Cr) were extracted using ethanol as a solvent and two extraction techniques. These methods are microwave-facilitated extraction and successive microwave-ultrasound-assisted extraction, resulting in Cr-1 and Cr-2, respectively. These two ethanolic extracts were investigated for several biochemical characteristics, including flavonoid content, phenolic content, antioxidant, anti-inflammatory, cytotoxic, and cytoprotective effects. The first and second characteristics were computed using the colorimetric AlCl3 and Folin-Ciocalteu colorimetric methods, respectively. The antioxidant char¬acteristic was investigated against two reactive species, named hydroxyl and DPPH. Also, the total reducing power was calculated in this regard. The anti-inflammatory-reducing characteristics of the extracts were evaluated employing three inflammation-progressing enzymes. The last two characteristics were assessed using MTT-based methodology in two malignant and one healthy cellular population, respectively. The outcomes demonstrated that the extract of microwave-facilitation (Cr-1) has the highest flavonoid and phenolic contents, as well as the best antioxidant activity. Furthermore, when compared to the other one, Cr-1 showed a greater inhibitory effect on inflammation-progressing enzymes and selectivity against COX2. At the applied concentrations, neither extract, however, had any antiprolifer¬ative effect on malignant or healthy cellular lines. Moreover, the extracts had no additional influence on the ability of 5-fluorouracil (5-FU) to stop the proliferation of malignant cells. However, when the extracts were individually applied with 5-FU, the cytotoxic capability of the drug in healthy cellular populations was substantially lowered. Given these findings, the authors concluded that using Cr-1 together with 5-FU may serve as a measure of normal cellular protection.
