Study on comprehensive treating Litsea Cubeba oil with β-cyclodextrin(Ⅱ) |

Abstract: | Using β cyclodextrin to enclose the limonene in Litsea Cubeba oil to improve citral content in Litsea Cubeba oil.The influencing factors of the inclusive reaction have been studied by orthogonal test.The results showed that the ratio of β cyclodextrin to Litsea Cubeba oil is the most important influencing factor of the inclusive reaction.The optimum conditions of the inclusive reaction are as follows:the size of β cyclodextrin is 48 μm,the water content of β cyclodextrin is about 14%,the catalyst amount is 0.2 g,the ratio of β cyclodextrin to Litsea Cubeba oil is 1.0 g:4.0 ml,the reaction time is 90 min.Citral content could be raised to 83% in the final product. |
