The plants of Combretum (Combretatace) are widely used in folk medicine for the treatment of leprosy, cancer, hepatitis, diarrhea, and respiratory infections in different parts of Asia and Africa. Some types of compounds such as stilbenes, phenanthrenes, triterpenes, and their glycosides were isolated from Combretum species, and these compounds showed various activities [1]. Eleven species are widespread in China, and most of them are distributed in Yunnan and Hainan Province [2]. Some species were used for the treatment of bruises, abdominal pain, diarrhea, jaundice, hepatitis, and ascariasis in Chinese folk medicine [3, 4]. It is necessary to investigate the chemical constituents of Combretum species from China. As part of our work, ten compounds were isolated from Combretum punctatum spp. squamosum. Their structures were determined by spectroscopic analysis to be oleanolic acid (1), arjunolic acid (2) [5], arjungenin (3) [6], quadranoside I (4) [7], vitexin (5) [8], methyl gallate (
