Abstract:

To study the toxic and side effects of ginkgolic acid and to explore the detoxification effect of Celtis sinensis Pers. extracts on ginkgolic acid, the active components in C. sinensis leaves, branches and bark were extracted and separated. And then the detoxification effect of each components on ginkgolic acid were compared on the basis of exploring the anti-proliferative effect of ginkgolic acid on HepG2 cells and the pro-inflammatory effect and contact sensitization of ginkgolic acid on mice. The results showed that the total ginkgolic acid, main ginkgolic acids C13:0 and C15:1 showed significantly inhibitory effect on the proliferation of HepG2 cells, and could lead to inflammation. The inhibition on the proliferation of HepG2 cells induced by C13:0 and C15:1 could be reduced by the n-butanol extracts(BA) and water-soluble extracts(Water) of C. sinensis leaves, 2# extracts of C. sinensis branches and 14# extracts of C. sinensis bark, and the cell survival rate could be increased from 26.7% to 63.0% at highest; T cell mediated inflammatory response could be significantly inhibited by 8# extracts of C. sinensis branches and 16# extracts of C. sinensis bark, and the highest inhibition rate on the proliferation of Con A-activated T cells was 95.4%.The total ginkgolic acid, main ginkgolic acids C13:0 and C15:1 had certain toxic and side effects, and excessive use of products with excessive ginkgolic acid content might lead to liver injury and allergy. Components that could inhibit the toxic effect of ginkgolic acid existed in the leaves, branches and bark of C. sinensis, and the extract of C. sinensis had potential application value in reducing the toxicity of ginkgolic products.

Key words: ginkgolic acid, extract of Celtis sinensis leaves, anti-liver injury, anti-inflammation
