From: Antitrypanosomal activity of aloin and its derivatives against Trypanosoma congolensefield isolate

Test substance Time (min) after which motility ceased vs. effective concentrations (mg/ml) Parasite motility
4.0 2.0 0.4 0.1
Exudate 25 40 55 >60 ++
Aloin 40 60 >60 >60 +
Aloe-emodin 20 40 55 >60 ++
Rhein 15 25 45 >60 +++
Diminazene aceturate 10 20 40 >60 +++
10% DMSO NE NE NE NE NE
  1. +++ = reduced highly, ++ = reduced moderately, + = reduced slightly, DMSO = dimethyl sulfoxide, NE = no noticeable effect on motility even after 60 min.
