บทคัดย่อ :
Twenty polyoxygenated triterpenes, including nineteen ursanes and one oleanane, were characterized
from the stem material of Siphonodon celastrineus (Celastraceae) through the application of spectroscopic
techniques and chemical transformation. Three of the ursane-type triterpenoids possessed the rare
13,27-cyclopropane ring skeleton.
