Anethole accounted for 82.65% of the whole oil. Selective isolation of anethole form the volatile oil was carried out using an inclusion crystalline method with 1,1,6,6- tetraphenylhexa- 2,4-diyne-1,6-diol inclusion complex with anethole . The crystal structure of the inclusion complex was determined by IR, 1^H NMR and single crystal XRD techniques.

This paperindicated that it was good for condensation reaction when benzene-ring bearingelectron-attaching groups. It also showed that and the 6-hydroxyl group could bereacted with acyl halide, haloid ether and halo alkene, but not with halo alkane. It wasnot only the first time to find that the reaction product of D-mannitol and aromaticaldehyde is tri-condensation derivatives, but also the first time to obtain thep-phthaldehyde-sorbitol derivatives containing eight hydroxyl groups.
