This article is a list of Acacia species (sensu lato) that are known to contain psychoactive alkaloids, or are suspected of containing such alkaloids due to being psychoactive. The presence and constitution of alkaloids in nature can be highly variable, due to environmental and genetic factors.
| 0.04-0.82% alkaloids in leaves and stems, 0.08% in ripe pods, mostly phenethylamine | ||
| DMT in bark (up to 1.6%) and in leaves (0.6-1.0%), young leaves mainly containing tryptamine;[1] 0.72% alkaloids from leaves and stems, mostly tryptamine[2] | ||
| DMT in bark (0.2-1.2%), 0.1% alkaloids from leaves (mostly NMT);[3] 1.5% alkaloids from leaves and stems, mostly tryptamine[4] | ||
| β-methyl-phenethylamine (N-methyl-phenethylamine), 2.4% in leaves; 3.2% alkaloids in aerial parts (stems, leaves, flowers) - about 70% was β-methyl-phenethylamine, with smaller amounts of phenethylamine | ||
| Published reports of DMT in the leaf derive from a misreading of a paper that found no DMT in leaves of this species. Besides this, there are independent claims of DMT in leaves and bark based on human bioassay, and traces of 5-MeO-DMT, DMT and NMT were tentatively identified by TLC in twigs. Root bark contains alkaloids that were not identified[5] | ||
| Dimethyltryptamine active levels in leaf[6] | ||
| Ash used in Pituri.[7] Ether extracts about 2-6% of the dried leaf mass.[8] Not known if psychoactive per se. | ||

| Has been claimed to contain tryptamine alkaloids[12] and significant amount of tryptamine in the seeds,[13] but this needs confirmation and supporting information | ||
| 5-MeO-DMT tentatively identified in stem bark | ||
| 0.02% alkaloids in spring (80% tetrahydroharman, 20% tryptamine), 0.028% autumn (tryptamine) and none in summer, with leaves of Californian plants;[14] traces of DMT and unidentified indoles tentatively detected in seeds | ||

| Hordenine, tyramine and N-methyltyramine in leaves;[16] 0.28-0.66% N-methylphenethylamine in leaves. Causes stock intoxications in Texas.[17] Claims of amphetamines, mescaline, nicotine and many other alkaloids[18] are suspect[19] | ||

| Tryptamine and DMT N-oxide from bark | ||
| 0.02-0.06% alkaloids from stems and leaves, consisting of tryptamine and phenethylamine; one screening found no alkaloids | ||
| Claims of DMT in the plant[20] have been referenced to works that do not support the claim. Needs research. | ||

| 0.02% alkaloids from leaves, including β-methyl-phenethylamine (tentatively identified) | ||
| Ash used in Pituri.[32] Not known if psychoactive. | ||
| May be psychoactive, as the root is used as an aphrodisiac, and may have been added to the Central American balché beverage. Claims of tryptamines in this species[33] might be speculation. Research needed. | ||

| Claimed to contain tryptamine, but without a reference. Needs research | ||
| 0.13-0.71% alkaloids from bark, consisting of NMT and DMT in about a 2:3 ratio;[51] both also present in leaves. Some varieties of the species are not good alkaloid sources. Tentative identification of 5-MeO-DMT in wood and twigs, NMT in root | ||
| Rumoured to contain DMT or similar psychoactive alkaloids | ||
| Some plants may contain DMT in the bark and leaf, but may have been misidentified as most do not. Traces of alkaloids detected in bark, leaf and seed; sometimes no alkaloids | ||
| Published reports of DMT in the leaf derive from a misreading of a paper that found no DMT in leaves of this species. Needs research | ||
| DMT, NMT, tryptamine, other alkaloids [52] | ||
| One published report of DMT in the leaf may derive from a misreading of a paper that found no DMT in leaves of this species. Later analysis tentatively found 5-MeO-DMT in stems, leaves and roots; DMT, NMT and 5-MeO-DMT were tentatively observed in seeds, but follow-up tests were negative.[53] Bark contains unidentified alkaloids[54] Bark in one sample subsequently found to contain an alkaloid which has an Rf value suggesting DMT.[55] | ||

A small population seems to contain mainly DMT in bark, with most also containing other alkaloids including NMT, tryptamine, harman and norharman; leaves may contain more NMT than DMT. Some assays showed tentative presence of 5-MeO-DMT and/or bufotenine but these are unconfirmed and other assays did not detect them[58] [59] | ||
| 0.016% DMT in leaf; a claim of NMT in this species is unreferenced | ||
| Claimed to be psychoactive, but supporting information is needed. Bark and leaves have been used to poison fish[60] | ||
| 0.3% DMT in leaf;[61] a claim of NMT could not be found in the reference given and needs verification. Species is rare and threatened | ||
| 0.11-0.29% alkaloids in leaves and stems, 0.11% from seeds and pods, mostly tryptamine and sometimes with phenethylamine also present; a later analysis found 0.06% tryptamine from leaves (w/w)[62] | ||

| Less than 0.01% total alkaloids in leaf, sometimes none. 0.4% DMT in single tree[65] | ||
| 0.01% Nicotine was reported from leaves, but identity of the plant was not certain;[66] claims of DMT and NMT in the plant[67] require verification or a proper reference | ||
| 0.025% alkaloids from leaves, including N-methyl-phenethylamine and N-methyl-tyramine (both tentatively identified). Claims of DMT, NMT, amphetamines, mescaline, nicotine and many other alkaloids[68] are suspect | ||
| 0.036% alkaloids from leaves, including β-methyl-phenethylamine, tyramine and N-methyl-tyramine | ||
| Ash used in Pituri. Not known if psychoactive. | ||
| A claim of β-methyl-phenethylamine, phenethylamine, amphetamines and mescaline in this species lacks a reference and is highly dubious | ||
| β-methyl-phenethylamine in leaves, tentatively identified | ||
| 0.003% DMT in leaf; claim of DMT in bark requires verification | ||

| 3.6% alkaloids from leaves and stem bark (40% NMT, 22.5% DMT, 12.7% 2-methyl-tetrahydro-β-carboline, and traces of N-formyl-NMT which might be an artefact of extraction)[69] | ||
| 0.21-0.35% alkaloids from leaves and stems, about 2/3 phenethylamine | ||
| Up to 0.89% alkaloids from leaves and stems, 0.05-0.17% from unripe pods, mostly phenethylamine | ||
| 0.008% alkaloids from leaves including β-methyl-phenethylamine and tyramine (tentatively identified) | ||
| Published reports of DMT in the leaf derive from a misreading of a paper that found no DMT in leaves of this species. Needs research | ||
| Tryptamine, in the leaf and stem (up to 83% of total alkaloids); alkaloid content was highest in autumn and spring (0.12-0.28%), lowest in summer and winter (0.03-0.08%) | ||
| Tentative positive for DMT in aerial parts of a 1 yr old plant, and 5-MeO-DMT in roots of 2 yr old seedlings; a formal screening found no alkaloids in leaf and stem. Appears to contain DMT based on human bioassays |
Species containing a concentration of alkaloids of 0-0.02% include:
