Shimoburo base

Songorine (Napellonine, Shimoburo Base 1, Bulletine G) Subdesculine... 

F. Songorine (Napellonine or Shimoburo Base I), Norsongorine, Songorine... 

D. Delcosine (Delphamine, Lucaconine, Takao Base I, Alkaloid C), Monoacetyldelcosine (Monoacetyllucaconine, Alkaloid B), and 14-Dehydrodelcosine (Shimoburo Base II)... 

The alkaloid delcosine was first isolated by Goodson 44) from the roots of D. ajacis L. and tentatively named alkaloid C. Marion and Edwards isolated delcosine from D. consolida 45) and it was later found that the two materials were identical 46). Another of the bases isolated by Goodson 44) was an acetylated alkaloid tentatively named alkaloid B, which gave rise to alkaloid C on hydrolysis. Thus alkaloid B is monoacetyldelcosine 46). The alkaloids lucaconine and monoacetyllucaconine, isolated from the roots of A. lucidtisculum Nakai 47-51), have also been shown to be identical with delcosine and monoacetyldelcosine, respectively 51). Likewise, the identities of Takao base I, from A.japonicum Decne. 52) and delphamine 53) have been found to be identical with delcosine 54, 55). The alkaloid previously reported as Shimoburo base II, from A.japonicum 56) is identical with 14-dehydro-...
