| Abstract: | We used 1,1,6,6-tetraphenylhexa-2,4-diyne-1,6-diol(A) as the host molecule to selectively recognize the component 1,8-cineole(B) in the volatile oil of Flos Magnoliae(Xin Yi). The inclusion compound(A+B) was formed as crystalline, and the structure was confirmed by means of IR, (1H NMR), and single crystal X-ray diffraction, with the 1∶2 molar ratios of the host to the guest. The component 1,8-cineole(B) was selectively isolated from the inclusion compound(A+B) by Kugelrohr vaccum technology, and then further characterized by IR, 1H NMR and 13C NMR. The whole components in the volatile oil of Flos Magnoliae(Xin Yi) and the isolation effect of 1,8-cineole isolated from inclusion crystals were analyzed by GC and GC-MS, respectively. The result indicate that the good isolation effect is given by the inclusion method, with purity and yield of the component 1,8-cineole(B) separated from the volatile oil of Flos Magnoliae are 100% and 85%, respectively. |
