Chemical compounds and pharmacological effects of Rabdosia excisa

Abstract

Many kinds of diterpenoids have been isolated from Rabdosia spp. Some of them have anti-microbial effects, counteract inflammation, and inhibit tumor progression activities. We conducted the present study in order to look for bioactive compounds in the medicinal plant Rabdosia excisa. In this study, five compounds were isolated from R. excisa; they were oridonin, isokamebakaurin, oleanolic acid, ursolic acid, and β-sitosterol. In order to identify the function of the extracts, the activity of antibiotics, anti-oxidation, and immunity test were carried out against these functions. Prospective results were observed in all of the tested items.
