Investigation of Inclusion Complex of Patchouli Alcohol with β-Cyclodextrin

Abstract

El objetivo de este estudio fue mejorar la estabilidad y la solubilidad en agua del alcohol de pachulí mediante la formación de complejos con β-ciclodextrina (β-CD). Las interacciones entre el alcohol de pachulí y la β-CD se caracterizaron por calorimetría diferencial de barrido (DSC), espectroscopía infrarroja por transformación de Fourier (FT-IR), difracción de rayos X en polvo (PXRD) y microscopio electrónico de barrido (SEM), respectivamente. De acuerdo con el método de modelado molecular, la formación de entalpía del huésped-huésped ilustró la configuración predominante y el valor más bajo ΔbGo fue de-10.8174 ±1.9235 kcal/mol, lo que sugiere que el complejo podría reducir la energía del sistema. El análisis de caracterización confirmó la formación del complejo de inclusión PA-CD, y los resultados indicaron la ventaja del complejo de inclusión en la estabilidad y las tasas de disolución. Estos resultados identificaron el complejo de inclusión PA-CD como una forma efectiva para el almacenamiento de PA, y aún era necesario estudiar un mejor método de inclusión.

L'objectif de cette étude était d'améliorer la stabilité et la solubilité dans l'eau de l'alcool patchouli en complexant avec la β-cyclodextrine (β-CD). Les interactions entre l'alcool de patchouli et la β-CD ont été caractérisées par calorimétrie différentielle à balayage (DSC), spectroscopie infrarouge à transformation de Fourier (FT-IR), diffraction des rayons X sur poudre (PXRD) et microscope électronique à balayage (MEB), respectivement. Selon la méthode de modélisation moléculaire, la formation d'enthalpie hôte-invité illustre la configuration prédominante et la valeur la plus faible ΔbGo est de-10,8174 ±1,9235 kcal/mol, ce qui suggère que le complexe pourrait réduire l'énergie du système. L'analyse de caractérisation a confirmé la formation du complexe d'inclusion PA-CD, et les résultats ont indiqué l'avantage du complexe d'inclusion dans la stabilité et les vitesses de dissolution. Ces résultats ont identifié le complexe d'inclusion PA-CD comme un moyen efficace pour le stockage de l'AP, et une meilleure méthode d'inclusion devait encore être étudiée.

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.

كان الهدف من هذه الدراسة هو تحسين استقرار الكحول الباتشولي وقابليته للذوبان في الماء عن طريق التعقيد باستخدام β -سيكلوديكسترين (β - CD). تميزت التفاعلات بين كحول الباتشولي وبيتا- سي دي بمسح تفاضلي لقياس السعرات الحرارية (DSC)، ومطياف فورييه لتحويل الأشعة تحت الحمراء (FT - IR)، ومسحوق حيود الأشعة السينية (PXRD)، ومجهر المسح الإلكتروني (SEM)، على التوالي. وفقًا لطريقة النمذجة الجزيئية، أوضح تكوين المحتوى الحراري لضيف المضيف التكوين السائد وكانت أقل قيمة ΔbGo هي -10.8174 ± 1.9235 كيلو كالوري/مول، مما يشير إلى أن المركب يمكن أن يقلل من طاقة النظام. أكد تحليل التوصيف تشكيل مجمع شمول PA - CD، وأشارت النتائج إلى ميزة مجمع الشمول في معدلات الاستقرار والانحلال. حددت هذه النتائج مجمع تضمين PA - CD كطريقة فعالة لتخزين PA، ولا تزال هناك حاجة إلى دراسة طريقة تضمين أفضل.
