摘要: 采用超声法制备了右旋龙脑/羟丙基-β-环糊精包合物,并用差示扫描量热法和X-射线衍射法鉴定,然后采用气相色谱法,以右旋龙脑含量为指标,分别对包合物进行挥发性、热稳定性、抗光解性和相溶解度实验. 结果表明: 在常温、光和热的因素影响下,包合物中右旋龙脑的含量明显高于混合物,这表明包合物具有一定的抗光解性和热稳定性,其稳定性明显优于单纯的右旋龙脑,便于长久贮存而不改变疗效; 羟丙基-β-环糊精浓度为0~8mol /L 时,右旋龙脑的浓度随着羟丙基-β-环糊精浓度的增加而增加,表明右旋龙脑形成包合物后,其溶解性得到了显著提高.

Abstract:

d-borneol /hydroxypropy-β-cyclodextrin ( HP-β-CD) inclusion complex was prepared through ultrasound method,and was confirmed by means of the differential scanning calorimetry ( DSC) and the X-ray diffractometry ( XRD) . Then,the volatility,thermal stability,anti-photodecomposition and phase solubility of the inclusion complex were tested with the d-borneol content as the index,which is determined via gas chromatography ( GC) . The results show that,under the influence of light and heat at the room temperature,the content of d-borneol in the inclusion complex is higher than that in the physical mixture of d-borneol and hydroxypropy-β-cyclodextrin,which indicates that the inclusion complex is of anti-photodissociation,thermal stability and a stability obviously superior to that of pure d-borneol,so it can be conveniently stored with the efficacy being preserved for a long time; and that the d-borneol concentration increases with the HP-β-CD concentration varying from 0 to 8mol /L,which means that the solubility of d-borneol is significantly improved after the inclusion.

Key words: d-borneol, hydroxypropy-β-cyclodextrin, inclusion complex, stability
