Funny, I was walking dogs up the canal and I stood and looked at some daffodils and wondered what compounds might be hidden in them. Good stuff!

This kind of information is really helpful to those of us who teach undergraduate organic chemistry. This summary will allow me to try to connect organic chemistry with the day-to-day lives of my students when I lecture in a few minutes. (Our daffodils are just starting to emerge.)

Providing this type of information (for educators and others) is a great use of ACS resources.

No wonder deer avoid them, while munching on tulips right next door.

That why they recommended in this New Mexico mountain community with a large population of deer. Deer eat all the rest of the spring flowers.

I know that lycorine and galantamine are in the bulb of the daffodil, but what are the levels and concentrations of these compounds in the flowers themselves?
