Eremostachys laciniata
(Lamiaceae)
a rich source of structurally different flavonoids is
ignored for its micronutrients level and many biological
activities. In this study, the plant was investigated for
different micronutrients including, phosphorus (P), nitrogen
(N), boron (B), zinc (Zn) and manganese (Mn) and compared
with adequate level of micronutrients for orchid crops. The
crude methanol extract and different fractions of E.
laciniata were also investigated for in vivo
antinociceptive activity using Tail-flick model. Except for
boron, all other micronutrients investigated were well in
the limits recommended for orchid crops. Crude extract and
different fraction thereof showed excellent increase in
latency time along with certain central effect of causing
sedation, ataxia and hind limb extension. This increase in
latency time is not only due to analgesia but may be a
combined effect of sedation, ataxia and analgesia. The plant
may be a useful source in future for the isolation of
natural product with analgesic property.
