Ayahuasca: alkaloids, plants & analogs
Section 3 : Part 2 :
Alkaloid distribution within Phalaris
Hagman et al. 1975 Found that the upper third of the regrowth has the highest alkaloid concentration overall. [There were points it was only as strong as the middle third but these were the low values. (Regrowth in the middle third did show a substantial increase in alkaloids.)]
They reported a mean concentration of 12 P. arundinacea clones grown in a greenhouse versus those grown in the field.
Part | % total alkaloid | by dry weight. |
Greenhouse | Field | |
Leaf tip | 0.29 | 0.27 |
Blade base | 0.23 | 0.26 |
Leaf sheaths | 0.07 | 0.10 |
Stem | 0.04 | 0.11 |
Marten et al. 1973 reported the following average alkaloid concentrations in P. arundinacea [Using only regrowth and harvesting when the plants were at 20 to 60 cm tall and still in vegetative stage]:
- 0.29% in upper half of leaf blades
- 0.23% in lower half of leaf blades
- 0.07% in leaf sheaths
- 0.04% in stems
- 0.05% in inflorescences.
- and when above ground parts was 0.19% the rhizomes was 0.01%.
