Production process for removing pesticide residue from extract of Ginkgo biloba

Abstract

The invention discloses a production process for removing pesticide residue from extract of Ginkgo biloba (EGB), aiming to remove the pesticide residue in EGB and ensuring the quality of the EGB. The production process is characterized by comprising the following steps of: heating, stirring and dissolving an EGB sample by a water solution containing ethanol; cooling, adding active carbon, stirring and adsorbing; filtering and recycling filtering liquid; and concentrating and drying the filtering liquid to obtain finished products. The production process comprises the concrete steps of weighing 10-100 kg of the EGB sample, adding 1000 L of the 30-70% ethanol solution, heating and stirring to dissolve the sample completely; cooling to 30-50 DEG C, adding active carbon powder which accounting for 1-20% of the weight of the EGB, stirring and adsorbing for 30-60 min; filtering and recycling the filtering liquid; and finally concentrating and drying the filtering liquid to obtain finished products.

Description

technical field [0001] The invention relates to a production process for removing pesticide residues in ginkgo biloba extract. Background technique [0002] The main components of Ginkgo biloba extract (EGB) are ginkgo flavonoids and terpene lactones. EGB has physiological activities such as antagonizing platelet activating factor (PAF), anti-cerebral ischemia and hypoxia, reducing blood lipid, scavenging oxygen free radicals, relaxing bronchial smooth muscle, anti-allergy, anti-inflammation and enhancing nervous system activity. Clinically, EGB is used to treat coronary heart disease, angina pectoris, cerebral ischemia, brain aging, brain insufficiency, senile dementia, asthma, etc. [0003] In industries such as food, nutraceuticals, and pharmaceuticals, EGB has been widely used. However, due to the widespread use of pesticides, the problem of pesticide residues in soil, water, air and other environments has become more and more serious, and there are also pesticide resi...
