STUDY ON ORAL ULCER POWDER USING TEMPERATURE-DEPENDENT X-RAY DIFFRACTION TECHNIQUE
Journal Title: Topics in Chemical & Material Engineering (TCME) - Year 2018, Vol 1, Issue 1
Abstract
The temperature-dependent XRD (TD-XRD) technique was used to rapidly detect the three main ingredients (Indigo Naturals (IN), borneol, and alum) of Oral Ulcer Powder (OUP) and impurities introduced in the process of manufacture of OUP. The results show that the three main ingredients of OUP can be monitored by XRD. The hexagonal Ca (OH)2, the rhombohedral CaCO3, and a small amount of SiO2 survive in IN during the process called “Hit indigo with lime”. The alum in OUP mainly consists of aluminum potassium sulfate (KAl(SO4)2·12H2O), with a small amount of ammonium alum (NH4Al(SO4)2). The borneol in OUP gradually disappears with increasing T from 30 to 100°C, whereas, NH4Al (SO4)2 and rhombohedral CaCO3 survive in OUP. The TD-XRD technique can provide evidence of stability of pharmaceutical preparations and set up a rapid detection method for quality control of OUP.
