摘 要: | 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 com-pound (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.
