seems possibly interesting especially for colder climates found this
L. bicolor var. japonica from Japan has yielded tryptamine alkaloids (0.068-0.106% crude alkaloids from leaf, 0.206% in root-bark) - leaves contained DMT (major alkaloid - 0.25% in one test), 5-MeO-DMT, 5-OH-DMT and 0.035% lespedamine (1-MeO-DMT - possibly active by smoking); root-bark contains these alkaloids in greater amounts, as well as DMT N-oxide and 5-MeO-DMT N-oxide. Leaves also contain the carbohydrate D-pinitol; unripe seeds contain the amino acid canavanine and flavonoids orientin, isoorientin, quercetin, isoquercetin, kaempferol and trifolin (Goto, et al. 1958. Chemical Abstracts 52:14082; International Legume Database and Information Service and Chapman & Hall Chemical Database. 1994. Phytochemical Dictionary of the Leguminosae. Vol.1.Plants & their constituents. Chapman & Hall, London.; Morimoto, H. & Oshio, H. 1965. Justus Liebigs Annalen der Chimie 682:212-218;
Morimoto, H. & Matsumoto, N. 1966. Justus Liebigs Annalen der Chimie 692:194-200). Independent TLC-analysis of L. bicolor var. bicolor has found alkaloids to be in greater concentration in the seeds; no alkaloids were detected in the 1st year's growth (Trout, K. ed. 1997. Tryptamines From Higher Plants: Reported occurrences of a few tryptamines. Trout's Notes (#FS-X5).).

swim read once and this needs to be confirmed - will soon - but a local spp of this plant is smoked, i think the common name is rooi dagga (rooi = red dagga = common name for cannabis or leonotis leonoris)
kinda like a ganja substitute - swim thinks this plant is fairly common around where he lives - swim will go look for some and take pix.

Great information. First time I've seen actual percentages on this species.



Note: Bulk seed is readily available and not very expensive, as this plant is commonly used in wildlife forage plantings.

Lespedeza bicolor is quite common throughout the eastern USA, so keep an eye out for it.
(Google images of this species)

I'm sure someone would be willing to wildcraft and donate plant material to some of the nexus' resident chemists for further analysis.

Found this thread over at SAB, interesting reading.

Seems that the only reported successful bioassays with this species involved oral consumption of leaves along w/ an MAOI.

Comparable amounts of rootbark w/ MAOI reportedly proved ineffective.

And, one unnamed source indicates that an A/B with defats on 100g dried spring leaves yielded a small amount of interesting smelling, yet completely inactive when vap'd, goo.

One could speculate that perhaps active tryptamines are indeed present in leaves allowing for the successful oral usage w/MAOI, yet the overall alkaloid profile is too diluted w/ inactive accompanying tryptamines to be useful via vaporization.

Just some thoughts.
