Abstract : Ginkgo biloba leaf extract (EGb) is high in bioactive components (over 170), which are used in food additives, medicine, cosmetics, health products, and other sectors. Nonetheless, ginkgolic acids (GAs) in Ginkgo biloba (GB) have been identified as the primary source of EGb's adverse effects such as embryotoxicity, cytotoxicity, neurotoxicity, and inhibition of enzyme systems. As a result, the Chinese, European, and United States pharmacopeias all mandate that the GA concentration in EGb be less than 5 μg g −1 . This review looked at the toxicity of ginkgolic acid (from in vitro and in vitro trials) as well as the technologies (such as adsorption/desorption, enzymatic degradation, counter-current chromatography, liquid–liquid microextraction, dual-frequency ultrasonic-solvent extraction, deep eutectic solvent, etc .) used to lower the GA to the desired concentration. These technologies' advantages, disadvantages, viability, and future trends were compared. In addition, several pharmacological significances of GA extraction, such as anti-microbial, anti-inflammatory, anti-tumor, etc ., were discussed, as well as future directions.
