XLOGP is an atom-additive method for calculating the octanol/water partition coefficient(logP). It gives the logP value for a give compound by summing the contributions from component atoms and correction factors.

Alkaloid XlogP3 list
- -1.4 - Muscimol
- -1.6 - Psilocybin
- 0.6 - Harmalol
- 0.7 - Mescaline
- 1.2 - Harmaline
- 1.2 - Bufotenine
- 1.5 - 5-MeO-DMT

- 2.5 - Elemicin

- 3.6 - Harmine
- 3.6 - Harman
- 3.9 - Ibogaine
Lower XlogP values are more water soluble, and higher XlogP values are more non-polar soluble.
Solvent XlogP list
- -0.7 - DMSO
- -0.5 - Methanol
- -0.1 - Ethyl Alcohol
- 0.2 - Acetone
- 0.4 - IPA
- 0.4 - MEK (Methyl Ethyl Ketone)
- 0.7 - Ethyl Acetate
- 0.9 - Ethyl Ether
- 1.5 - DCM
- 2.1 - Chloroform
- 2.5 - Toluene
- 2.5 - Xylene
- 3.7 - Limonene
- 4.3 - Heptane (similar to naphtha)
 |
Note: | Toluene and xylene, will only usually extract alkaloids with an XlogP of about 1.7 or higher. Heptane/naphtha will only extract the highly non-polar alkaloids with an XlogP of about 1.8 or higher (5-MeO-DMT, DMT, and NMT). As the solvent gets more non-polar, it extracts less and less alkaloids. XlogP calculations are never completely accurate and there are always exceptions to these solubility guides. |
LogP calculators
There are many logP calculators or predictors available both commercially and for free.
- Chemistry Development Kit
- JOELib
- ACD/LogP DB a commercial application that calculates LogP values and includes the largest commercially available database of experimental logP values with calculation of Rule-of-5 parameters
- ACD/LogP Freeware Download the free logP calculator
- Simulations Plus - S+logP an application for calculating logP with high accuracy[1]
- ALOGPS Free online calculations and comparison of 10 logP methods
