3.1. Z. officinale extract
In Fig. 2, the ZO extract at concentrations 10 mg/ml, 1 mg/ml,
100lg/ml, 10lg/ml and 1lg/ml effectively reduce the RM to 0,
30.98, 93.72, 88.12 and 87.95%, respectively after 24 h. The most
effective concentration in these series was 10 mg/ml and the least
effective concentration (with RM < 50%) was 1 mg/ml (p< 0.05).
The lower concentration values in these series did not show any
significant difference in microfilaricidal activity between each
other based on the statistical analyses despite these concentrations
exhibiting some but unappreciable inhibition of the microfilarial
movements.
3.2. A. paniculata and T. crispa Miers
The AP extract showed inhibitory effects on microfilarial move-ments as demonstrated inFig. 3, with the concentration of 10 mg/
ml effectively reducing the RM to 7.48% by the 24th h. The same
inference can be said about the TC extract, also demonstrating a re-
