A method for the extraction and isolation of alkylphenols in ginkgo biloba leaves was introduced , through the TLC and HPLC preparation , Six monomers were acquired.
By UV,IR,MS,1H-NMR and 13C-NMR spectral analysis , the structures of the compounds were identifited as:
1. 3-(8- pentadecenyl (phenol
2. 3-(4(z),7(z)-heptadecadienyl( phenol
3. 3-(10-heptadecenyl( phenol
4. 6-(8- pentadecenyl (salicylic acid
5. 6-(10-h...
