The present study represents the screening of the protective effects of herbal methanolic extracts from Baekdu mountain against tacrine-induced cytotoxicity in HepG2 cells. Tacrine is an acetylcholinesterase inhibitor, and used for the treatment of Alzheimer's disease. However, administration of tacrine for the treatment of Alzheimer's disease results in a reversible hepatotoxicity in 30-50% of patients, consequently limiting clinical use. Therefore, studies for natural products with protective effect on the tacrine-induced hepatotoxicity would be valuable as providing potential therapeutic use. 109 plant sources were collected in Baekdu mountain, and extracted with methanol. These extracts had been screened the protective effects against tacrine-induced cytotoxicity in HepG2 cells at the 100 and 300 ㎍/ml. Of these, ten methanolic extracts, roots of Ampelosis japonica, aerial parts of Berberis amurensis, aerial parts of Sedum aizoon, aerial parts of Lespedeza tomentosa, aerial parts of Lespedeza juncea, aerial parts of Hypenricum ascyron, stem barks of Syringa reticulata, fruits of Gleditsia japonica, aerial parts of Chamaenerion angustifolium, branches of Ginkgo biloba, showed significant protective effects against tacrine-induced cytotoxicity in HepG2 cells.
