Mok-Mun, Wrightia arborea (Dennst.) Mabb., Wrightia pubescens R.Br.Abstract
“Stem bark of Mok-Mun” is medicinal plant used in Thai traditional medicine. Originating from the stem bark of two species are Wrightia arborea (Dennst.) Mabb. and Wrightia pubescens R.Br. The Mok-Mun stem bark sold in herbal drug stores, look like small blocks and are similar to each other. It is difficult to identify the species of Mok-Mun crude drug. Therefore, this comparative study aimed to investigate TLC chromatogram and phytochemical data of Mok-Mun stem bark in both species. The result of the TLC chromatogram exhibited that the mobile phase dichloromethane: methanol:formic acid (7:3:0.2) showed different band color at hRf = 47. A phytochemical screening study of both species indicated the presence of triterpenoids. The results exhibited the small difference. The comparison of biological activities of two types Mok-Mun is required to confirm whether these plants can be used interchangeably to prepare the traditional medicines.
