Biological Activity
Description: Kolavenol shows a trypanocidal activity with an IC50 value of 2.5 microg/ml (8.6 microM) against Trypanosoma brucei rhodesiense, the causing agent of the acute form of human African trypanosomiasis.
Targets: Antifection
In vitro:
J Ethnopharmacol. 1998 Jul;61(3):179-83.
Bioassay-guided isolation of a diastereoisomer of kolavenol from Entada abyssinica active on Trypanosoma brucei rhodesiense.[Pubmed: 9705008 ]

METHODS AND RESULTS:
Bioassay-guided fractionation of the dichloromethane rootbark extract of Entada abyssinica (Leguminosae), a plant used by traditional healers in Uganda for the treatment of sleeping sickness, led to the isolation of a diastereoisomer of the clerodane type diterpene Kolavenol.
CONCLUSIONS:
This is the first report on this compound. It showed a trypanocidal activity with an IC50 value of 2.5 microg/ml (8.6 microM) against Trypanosoma brucei rhodesiense, the causing agent of the acute form of human African trypanosomiasis.
Kolavenol Description
Source: The herbs of Eupatorium adenophora
Solvent: Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
Storage: Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).

Wherever possible, you should prepare and use solutions on the same day.
