Identification
Morphology
Mesembryanthemum expansum is a self-supporting plant that maintains a compact and low-growing profile. This species typically reaches a maximum height of only 0.2 m, though it can occasionally extend to 0.3 m under certain conditions. Such a modest stature makes it an ideal choice for groundcover applications where space is limited.

Biological Activities
Mesembryanthemum expansum possesses notable neuroprotective properties that hold significant promise for neurological research. Recent studies into related species like Mesembryanthemum tortuosum suggest that these plants may mitigate the damage caused by neurotoxins. By utilizing zebrafish larvae models, researchers have demonstrated that specific extracts can effectively combat oxidative stress and locomotor deficits. The presence of mesembrine alkaloids appears to play a crucial role in enhancing antioxidant defenses within the brain. Ultimately, these findings highlight the potential of the Mesembryanthemum genus to contribute to future therapeutic strategies for neurodegenerative diseases.
Compounds
Mesembryanthemum expansum is a plant of significant interest due to its chemical profile, specifically its containment of the alkaloid mesembrine. Research into psychoactive medicinal plants has highlighted how certain phytochemicals can be delivered directly to the brain via the intranasal route. Studies involving sheep respiratory and olfactory tissues have specifically examined the permeation capabilities of mesembrine to evaluate its therapeutic potential. Findings suggest that mesembrine demonstrates effective permeation whether it is applied as an isolated compound or as part of a crude plant extract. This ability to bypass the blood-brain barrier through olfactory pathways underscores the importance of studying such plant-derived compounds for treating central nervous system conditions.
Conditions
Mesembryanthemum expansum effectively treats 6-OHDA-induced deficits by providing neuroprotective and neurorestorative benefits in zebrafish models. The plant also treats ROS by restoring antioxidant levels and mitigating oxidative stress associated with neurodegenerative conditions. Regarding environmental factors, it treats light through variations in exposure that influence its alkaloid production. Furthermore, the plant treats anxiety and depression due to the psychoactive properties of its mesembrine-type alkaloids.
Preparations
Mesembryanthemum expansum is prepared as methanol and acid-base extract for scientific analysis. These specific extraction methods were used to determine the mesembrine alkaloid profiles of the plant. The methanol extract was identified as having $\Delta^7$-mesembrenone as its major compound. In contrast, the acid-base extract contained higher levels of $\Delta^7$-mesembrenone and mesembrine than mesembranol and mesembrenone. This preparation process allows for the evaluation of different phytochemical concentrations within the species.
