Two new dammarane-type triterpene sapogenins from Chinese red ginseng

Listed in DataCite

Two new dammarane-type triterpene sapogenins were isolated from the Chinese red ginseng.

Description

The new sapogenins were named as 24,26-dihydroxy-panaxdiol ( 1 ) and 24-hydroxy-panaxdiol ( 2 ). Their structures were elucidated by the combined analysis of NMR and mass spectrometry as 20( S ),25( R )-epoxydammarane-3β,12β,24β,26-tetraol ( 1 ) and 20( S ),25-epoxydammarane-3β,12β,24α-triol ( 2 ).

The complete signal assignments of the two compounds were carried out by 2D NMR spectral and NOE differential spectroscopy analysis.
