IMHO you should read this paper from Chao et al ("Ergoline alkaloidal constituents of hawaiian baby wood rose, argyreia nervosa", 1973) (diagram on p2).
But be aware that as it seems Ergine (LSA) is not the substance you actually want.
(for details see the thread linked above).
But if you make pure Ergine, it would be perfect to make some TLC tries, to know, what exactly happens with the alleged LSA->LSH conversion.
EDIT:
BTW, it would be interesting to know, how exactly you did extract them to get LSD like effects. (including all the times for every step, until ingestion)
I claim not that this is the truth. As this is just what got manifested into my mind at the current position in time on this physical plane. So please feel not offended by anything I say.
