Deskripsi
A new cycloartan-type triterpenoid, 9,19-cyclolanost-24-en-3-one,21,23-epoxy-21,22-dihydroxy (21R, 22S, 23S), was isolated from the leaves of Lansium domesticum Corr cv kokossan. The chemical structure of 1 was elucidated on the basis of spectroscopic data, X-ray diffraction and comparison with those related compounds previously reported.
