Many of the reports are very useful. Just because you personally are not interested in them I wouldn't say they are not useful. it is still interesting to know what is present in the snuff. Agurell using gas chromatography. Many alkaloids were reported. The bark leaves and flowering shoots were all evaluated and it was identified as V. theiodora including those in the book.
Not to sound like a dick but i am not sure that you looked very hard as there are many well done studies using this plant:
Virola theiodora (Benth) Warburg
128 gm of leaves and stems gave 93 mg. of crude basic fraction. They were unable to find substituted tryptamine (negative vanUrk's) and did not investigate further.
235 gm. of bark yielded 40 mg. of crude basic fraction;
from 10 mg. of which the following was isolated:
1 mg. of 2-methyl-6-methoxy-1,2,3,4-tetrahydro-β-carboline
1 mg. of N,N-dimethyltryptamine
2 mg. of N-methyltryptamine
and 2 components which were not identified
Cassady et al. (1972) in Mothes; pp.95-99
[Schultes #24595; Origin: Manaos, Brazil]
250 mg. of alkaloid / 100 gm. of dry bark:
52% N,N-dimethyltryptamine
43% 5-methoxy-N,N-dimethyltryptamine
4% 6-methoxy-2-methyl-1,2,3,4-tetrahydro-β-carboline
1% N-methyltryptamine
17 mg. of alkaloid / 100 gm. of dry roots:
63% 5-methoxy-N,N-dimethyltryptamine
22% N,N-dimethyltryptamine
15% 5-methoxy-N-methyltryptamine
470 mg. of alkaloid / 100 gm. of dry flowers: & shoots:
93% N,N-dimethyltryptamine
7% N-methyltryptamine
44 mg. of alkaloid / 100 gm. of dry leaves:
99% N,N-dimethyltryptamine
Tr. 5-methoxy-N,N-dimethyltryptamine
(Holmstedt et al. 1980 says 100% DMT)
Agurell et al. 1969
[Schultes #24626; Origin: Tototobi, Brazil]
65 mg. of alkaloid / 100 gm. of dry bark:
95% 5-methoxy-N,N-dimethyltryptamine
5% N,N-dimethyltryptamine
21 mg. of alkaloid / 100 gm. of dry leaves:
98% N,N-dimethyltryptamine
2% 2-methyl-1,2,3,4-tetrahydro-β-carboline
