Interesting link. Where is that from? The only issue I saw was 'figure A', or at least the first picture, talks about the steroid as an aglycan when there is a sugar bound to it, so it is glycosylated. Later on when they show the OH instead of the glycan it is appropriately an aglycan. End of the day though, the stuff is bad for you so be careful. Digitalis, one of the molecules listed in the linked information, I think was the poison the twins used in the episode of the X-Files called Eve. I don't know how accurate the show was, but they described it as being very sweet flavored so perhaps if you have worked with the material and taste anything on your fingers that is oddly sweet call poison control ASAP.
