hi doc-

the harmala page could use some work too- this morning i put up redirects from harmine, harmaline, etc as there were none, and i put up the chemical names and formulas. but i don't at all feel comfortable actually writing about harmala; you've corrected my constant confusion about all that stuff on several occasions. Its good to see you around here!Heah 19:08, 19 Mar 2005 (UTC)


Personal test field

Currently, I'm trying to properly cite Schultes (1986) with the Harvard citation template for the citation, and the Citation template for the reference. Seems to work nicely but there's apparently no way to click somewhere in the reference to go back to the citation with this combo. Or I haven't found it yet...

Solved: The solution to have a backlink to the text is to have separate sections for references and bibliography, and to use the handy Footnotes <ref> tag in text body with the Harvard citation template embedded.


This nicely fits with my referencing habits but a new problem arose: When I tried the <refname ="blah"> tag, that allows multiple citations to the same reference, again with the Harvard citation template, it didn't work (the tag code is displayed and the entry in the "Notes and references" section disappears). Maybe a solution exists but finding the relevant info is much more difficult and time consuming than with the the last puzzle.

Solved: The correct syntax of the Footnotes "refname" tag, that allows multiple citations to the same reference, is <ref name="blah">, i.e. with a space between "ref" and "name". I can thus now make multiple citation to Schultes' paper[1] that point to the same Harv template-formatted reference.

[edit] Phytochemistry and pharmacology

The identification of B. caapi active components, and determination of their pharmacological properties proved to be a long, saltatory, and still unfinished task. [1][2]

[edit] Timeline

1905. Colombian MD and naturalist Rafael Zerda Bayón obtains a vaguely crystallized sludge from specimen of (probably) B. caapi he brought back from an expedition in the Caquetá and Putumayo areas. He believes to have almost isolated the active principle of the vine, that it is an alkaloid, and names it "telepathine".


1957. American chemists Francis Hochstein and Anita Paradies, from the Pfizer Research Laboratories, isolate harmine, harmaline, and, for the first time, d-tetrahydroharmine (THH) from botanically well identified samples of B. caapi stems "collected on the Napo River, near Iquitos, Peru".[3]

β-carboline alkaloids identified in dried stems of B. caapi in at least 2 quantitative studies
Study Method Samples Origin Harmine (mg/g) THH (mg/g) Harmaline (mg/g) Harmol (mg/g)
Rivier & Lindgren (1972) GC/MS 13 Mostly from the Upper Purus River area, Peru 2.6 ± 1.3 0.8 ± 0.9 0.2 ± 0.2 Range: "trace" to 0.6
McKenna et al. (1984) HPLC 6 Mestizo Peruvian cultivars, mostly from Tarapoto and Iquitos areas 3.9 ± 2.5 1.5 ± 1.0 1.9 ± 1.4 0.3 ± 0.5
Callaway et al. (2005) HPLC 33 Mostly UdV cultivars from "22 sites throughout Brazil" (p. 145) 4.8 ± 2.1 1.0 ± 0.8 0.5 ± 0.2 -
