Koelpinin- A, B and C — three triterpenoids from Koelpinia linearis

Three new triterpenoids, designated as koelpinin - A, B and C and characterised as 28- nor-lup-12,17-dien-3β,16α-diol,3β-acetoxy-28- nor-lup-12,17-dien-16α-ol and 28- nor-lup-12,17-dien-3β-ol-16-one, respectively, together with 30- nor-lup-3β-ol-20-one, taraxeryl acetate and germanicol, were isolate...

Description
Summary:Three new triterpenoids, designated as koelpinin - A, B and C and characterised as 28- nor-lup-12,17-dien-3β,16α-diol,3β-acetoxy-28- nor-lup-12,17-dien-16α-ol and 28- nor-lup-12,17-dien-3β-ol-16-one, respectively, together with 30- nor-lup-3β-ol-20-one, taraxeryl acetate and germanicol, were isolated, from the aerial parts of Koelpinia linearis. 13 C -NMR shifts were assigned after performing APT and DEPT experiments.
