Summary

1.Ungernia severtzovii has yielded lycorine, hippeastrine, 1-narwedine, d-narwedine, dl-narwedine, ungerwine, unsevine, galanthamine, tazettine, pancratine, and ungminorine; 1-narwedine and unsevine have been obtained from the plant for the first time.

2. Unsevine has the structure of 9, 10-methylenedioxy-5-methoxy-12-hydroxy-N-methylbenzopyranoindole with a double bond between C3a and C4.

3. Interconversions of unsevine, ungerine, and hippeastrine have been effected.
