The prepared Star Anise Oil microcapsules had relatively low oxidation, and degenerated severely over 120℃.

同时表明试验制得的八角油树脂微胶囊在低温度下被氧化的程度较小，而在120℃以上，微胶囊受其影响比较大，发生比较严重的变质。

THE FIRST TOTAL SYNTHESIS OF TAXAMAIRIN B Taxamairin B, representive of rare naturally-occuring rearrang-ed 9(10→20)-abeo-8, 11, 13-triene diterpenoids, has been firstsynthesized by a eleven-step route in an overall yield of 8.19%,starting from commercially available catechol and 1,3-cyclohexan-dione. The improved Friedel-Crafts annulation, thermodynamicallycontrolled-geminal pairing methylation, the selective oxidation ofallyl group and the selective reduction of the less-hindrancecarbon-carbon double bond are the key steps.
