The objective of this study was to improve the stability and water-solubility of patchouli alcohol by complexing with β-cyclodextrin (β-CD). The interactions between patchouli alcohol and β-CD were characterized by differential scanning calorimetry (DSC), Fourier transformation-infrared (FT-IR) spectroscopy, powder X-ray diffraction (PXRD), and Scanning electron microscope (SEM), respectively. According to molecular modeling method, the enthalpy formation of host-guest illustrated the predominant configuration and the lowest value ΔbGo was -10.8174±1.9235 kcal/mol, suggesting the complex could reduce the energy of the system. The characterization analysis confirmed the formation of PA-CD inclusion complex, and the results indicated the advantage of the inclusion complex in stability and dissolution rates. These results identified PA-CD inclusion complex an effective way for the storage of PA, and better inclusion method still needed to be studied.
本研究的目的是通过与β-环糊精(β-CD)复配来提高广藿香醇的稳定性和水溶性。分别采用差示扫描量热法(DSC)、傅立叶变换红外光谱法(FT-IR)、粉末 X 射线衍射法(PXRD)和扫描电子显微镜(SEM)对广藿香醇和 β-CD 的相互作用进行了表征。根据分子建模方法,主客体形成的焓为主要构型,最低值ΔbGo为-10.8174±1.9235 kcal/mol,表明该配合物可以降低体系的能量。表征分析证实了 PA-CD 包合物的形成,结果表明包合物在稳定性和溶解速率方面具有优势。这些结果表明 PA-CD 包合物是储存 PA 的一种有效方法,而更好的包合物方法仍有待研究。
