Rastronols A, B, C, D, E, F, G, and H, a group of multioxygenated bitter principles with ent ‐kaur‐16‐en‐15‐one structure from Englerastrum scandens ALSTON ( Labiatae ) We have isolated from the leaves of Englerastrum scandens from Kenya eight new, highly oxygenated ent ‐kaur‐16‐en‐15‐ones named rastronol A, B, C, D, E, F, G, and H, and determined their structures mainly by spectroscopic techniques as 1, 8, 14, 17, 20, 29, 39 , and 51 respectively.
