| Abstract: |
The ice plant (Mesembryanthemum crystallinum L.) is a halophyte that could become an alternative crop because of its interest as a functional food and its adaptation to high‐saline soils. In this work, leaves from wild ice plants were compared with their cultivated counterparts in a soilless system at different salinities and light exposures for assessing growth parameters, moisture, fatty acid profiles, total carotenoids, phenolic compounds, vitamin C, antioxidant activity, and antiproliferative activity against the HT‐29 colorectal cancer cell line. Moisture ranged between 876 and 955 g kg−1, and wild plants contained higher proportions of α‐linolenic acid (58.7%–60.7% of total fatty acids) than cultivated ones (20.4%–36.6%). Vitamin C ranged between 819 and 1143 mg kg−1 fresh leaves. Higher salinity led to a larger production of carotenoids, whereas plant mass, total phenolic content, and antioxidant activity increased in plants grown using L8 NS1 and L8 AP67 lamps in comparison with white‐light ones. Phenolic profiles were assessed by LC coupled to a hybrid mass spectrometer Q‐Orbitrap. Total phenolic acid content was 3–4‐fold higher than that of flavonoids, and sinapic, p‐coumaric, gallic, 4‐hydroxybenzoic, and 2‐hydroxy‐4‐methoxybenzoic acids, as well as gallocatechin, occurred in all samples. Hydroalcoholic extracts of ice plant leaves showed dose‐ and time‐dependent antiproliferative activity against the HT‐29 human colorectal cancer cell line, and GI50 was between 920 and 977 μg mL−1 of plant extract. This work contributes to improving knowledge about the growth parameters, phytochemical profiles, and biological activities of wild and cultivated ice plants. [ABSTRACT FROM AUTHOR] |
