Two new triterpenoids from Nauclea officinalis
Listed in DataCite
Two new triterpenoids and three 27-nor-triterpenoids were isolated from the stems (with bark) of Nauclea officinalis .
Description
Their structures were identified to be 2β,3β,19α,23-tetrahydroxy-urs-12-en-28-oic acid ( 1 ), 2β,3β,19α,23-tetrahydroxy-urs-12-en-28- O -[β-d-glucopyranosyl (1-2)-β-d-glucopyranosyl] ester ( 2 ), pyrocincholic acid 3β- O -α-l-rhamnopyranoside ( 3 ), pyrocincholic acid 3β- O -α-l-rhamnopyranosy1-28- O -β-d-glucopyranosyl ester ( 4 ), pyrocincholic acid 3β- O -α-l-rhamnopyranosy1-28- O -β-d-glucopyranosyl-(1-6)-β-d-glucopyranosyl ester ( 5 ) by spectroscopic methods including 1D, 2D NMR and HR-MS analyses.
The cytotoxic activity of 1 – 5 against lung cancer A-549 cells was also investigated.
