The snail mucus provides several functions and is increasingly being exploited for medicinal and cosmetic purposes. This study aimed to determine the chemical profile of two snail mucus extracts: the garden snail (Helix aspersa) and the desert snail (Eremina desertorum). In addition, it elucidates the antityrosinase, antioxidant, and anticancer activities against the human cancer cell line epithelioid carcinoma (Hela). The mucus was extracted from the pedal glands of garden snails (H. aspersa) and desert snails (E. desertorum). 2,2‐Diphenyl‐1‐picrylhydrazyl assay and the content of catalase, glutathione‐S‐transferase, superoxide dismutase, and reduced glutathione were utilized to assess the antioxidative screening activity of the mucus extracts. Besides a tyrosinase inhibitor assay, anticancer activity on cervical cancer cells (Hela) was studied. Additionally, the two mucus samples' total protein, total lipid, fatty acid, and amino acid profiles were compared. The mucus from both snails exhibited antioxidant activity. E. desertorum is more effective in inhibiting tyrosinase activity and has better scavenging activity than H. aspersa mucus extract. Both extracts revealed inhibitory activity against Hela cells, with insignificant differences. Moreover, the results indicated higher protein, lipids, and fatty acids mucus content of E. desertorum extract than those of H. aspersa mucus extract. Both snail slimes' obtained different biological activities, and amino acid contents could be related to their specific functions and beneficial for medical applications, especially antihyperpigmentation. Research Highlights: Mucus from Egyptian land snails, Eremina desertorum, and Helix aspersa are a source for discovering novel drugsE. desertorum mucus has better scavenging activity than H. aspersa mucusMucus extracted from E. desertorum is more effective in inhibiting tyrosinase activity than H. aspersaE. desertorum mucus extract contains higher protein, lipids, and fatty acids content than H. aspersa [ABSTRACT FROM AUTHOR]
