    ABSTRACT

    Allicin, a bioactive compound found in garlic, exhibits remarkable pharmacological properties such as antimicrobial, antioxidant, and anticancer effects. Its therapeutic potential has garnered substantial attention, leading to efforts to refine extraction and quantification methods for precise analysis in garlic-based products. This review examines advanced techniques for allicin extraction from garlic, including Ultrasonic-Assisted Extraction (UAE), Supercritical Water Extraction (SCWE), and Microwave-Assisted Extraction (MAE). UAE employs ultrasonic waves to improve mass transfer and solvent penetration, optimizing allicin yield while reducing extraction time. SCWE utilizes the unique properties of water above its critical point to extract allicin efficiently and selectively, providing an eco-friendly alternative. MAE uses microwave energy to rapidly heat solvents, enhancing allicin extraction through improved penetration and dissolution. Alongside these extraction methods, this review highlights analytical techniques for allicin quantification, including High-Performance Liquid Chromatography (HPLC), High-Performance Thin-Layer Chromatography (HPTLC), and Ultraviolet (UV) spectroscopy. HPLC offers exceptional sensitivity and specificity for splitting and measuring allicin in complex matrices, making it invaluable for accurate pharmacokinetic studies and quality control of pharmaceutical formulations. HPTLC offers quick screening with minimal sample preparation, ideal for routine investigation and batch testing of garlic extracts. UV spectroscopy, a cost-effective technique, detects allicin through its characteristic absorption spectra, enabling quick evaluations of garlic product quality and stability. This review consolidates recent advancements in allicin extraction and quantification techniques, emphasizing their applications in the pharmaceutical, nutraceutical, and food sectors. Future research aims to optimize extraction parameters to maximize allicin yield and develop robust analytical methods to address the growing demand for quality assurance and therapeutic efficacy in garlic-based products.
