Description

technical field

[0001] The invention relates to a production process for removing polycyclic aromatic hydrocarbons in ginkgo leaf extract. Background technique

[0002] Polycyclic aromatic hydrocarbons (PAHs for short) refer to hydrocarbons containing two or more benzene rings in the molecule, which can be divided into aromatic fused ring type and aromatic non-fused ring type. Aromatic fused ring type refers to the hydrocarbons in which the adjacent benzene rings in the molecule have at least two shared carbon atoms, such as naphthalene, anthracene, phenanthrene, pyrene, etc.; aromatic non-fused ring type refers to the adjacent benzene rings in the molecule Only one carbon atom is connected between compounds, such as biphenyl, terphenyl, etc.

[0003] PAHs can cause cancer. Chemical carcinogenesis refers to the process in which chemicals cause normal cells to transform and develop into tumors. Chemical carcinogens can be divided into direct carcinogens and indirect carcino...
