Nukiangendines A and B, two novel 13,14-seco-abietanes from Abies nukiangensis

Abstract From Abies nukiangensis , two novel 13,14- seco -abietane diterpenes, nukiangendines A ( 1 ) and B ( 2 ) were isolated. Their relative structures were determined by extensive NMR and HRMS spectroscopic analysis. The absolute configuration of 1 was established by ECD calculations. Compound 1 showed significant anti-hepatitis C virus (HCV) effects.
