Abstract
1. Subject and source
Aerial parts of Mimosa pudica L. (Leguminosae-Mimosoideae) were collected
near Accra, Ghana. Voucher specimen (GC47684) was deposited in Herbarium GC
(Ghana Herbarium, Botany Department, University of Ghana, Legon).
2. Previous work
The interest in M. pudica (the so-called sensitive plant) has mainly been concerned
with chemistry and biology of the thigmonastic movement (rapid leaf movement
observed upon touching the leaves) and nyctinastic movement (slow movement con-
trolled by a biological clock) of the leaves, and several leaf-movement factors have
been refined (Kameyama et al., 2000; Ueda and Yamamura, 2000; Ueda et al., 2000).
Phenolics (Ueda et al., 2000; Josewin et al., 1999; Englert et al., 1994), norepi-
nephrine (Applewhite, 1973) and a non-protein amino acid leucenine (mimosine)
(Kleipool and Wibaut, 1950) have been isolated. A saponin (Jiang et al., 1990) and
a bufadienolide (Yadava and Yadav, 2001) were reported in M. pudica seeds.
