Abstract
Acharan sulfate, a sulfated glycosaminoglycan isolated from the giant African land snail Lissachatina fulica, exhibits promising therapeutic potential as a natural anticoagulant and biological agent. However, safely utilizing wild populations requires mitigating pathogenic microbial colonization, and systematic extraction protocols must be optimized.
In this investigation, we established a standardized laboratory rearing model for Lissachatina fulica. We evaluated natural antimicrobial treatments utilizing garlic essential oil and probiotic Lactobacillus casei, successfully achieving 100% inhibition of opportunistic pathogenic bacteria (Escherichia coli, Staphylococcus aureus, and Salmonella spp.) inhabiting the specimens.
Through gravimetric analytical protocols, we quantified the yield of purified acharan sulfate, extracting 0.28 g per 100 g of snail flesh and 0.16 g per 100 g of mucus. Subsequent physiological assays demonstrated an 89.40% anticoagulant activity within 30 minutes via in vitro clotting time measurement and a 32.09% thrombolytic activity within 1 hour via blood clot lysis assay, substantiating its potential for therapeutic biomedical formulation.
