Five unknown labdane diterpenoids Stevelins A–E (1–5), three known labdane diterpenoids (6–8) and three labdane norditerpenoids (9–11) were isolated from the Stevia rebaudiana. The structures were determined primarily via NMR spectroscopic data and HR‐ESI‐MS experiments. X‐ray crystallography using CuKα radiation was used to determine the absolute configurations of 1, and the absolute configurations...
