Structural distinction between sabandins A and B from Artemisia scoparia waldst. (Asteraceae).
The three possible isomeric structures of the sabandin coumarin were published by Reyes and Gonzalez in 1970. We have isolated two of these isomers sabandins A and B from Artemisia scoparia (Asteraceae) and distinguished by NOE difference NMR measurements.
