Three new triterpenoids, designated as koelpinin - A, B and C and character
ised as 28-nor-lup-12,17-dien-3 beta,16 alpha-diol,3 beta-acetoxy-28-nor-lu
p-12,17-dien-16 alpha-ol and 28-nor- lup-12,17-dien-3 beta-ol-16-one, respe
ctively, together with 30-nor-lup-3 beta-ol-20-one, taraxeryl acetate and g
ermanicol, were isolated, from the aerial parts of Koelpinia linearis. C-13
