Abstract |
: |
The use of medicinal plants in worldwide for the treatment of several
diseases has been documented. World Health Organization estimates that
more than 80% of people in developing countries depend on traditional
medicine for their primary health needs. Heavy metals are metallic elements
with high atomic number and poisonous to living organisms. Plants may
absorb heavy metals from soil, water or air. The purpose of present study
was to explore the evidence of heavy metals contamination in some
medicinal plants. The atomic absorption spectrophotometer was employed
for determination of heavy metals (Cd, Cr, Cu, Fe, Pb and Zn) in
Azadirachta indica, Phyllanthus niruri and Tinospora crispa and their soils
from Mandalay, Pyin Oo Lwin and Shwe Bo. Soil pH meter and Pocket
ProTM Tester were used for determination of physicochemical properties
(pH, conductivity, TDS and salinity) in its soil and water. Some of these
plants and all soils contained metals, which were within permissible limit.
Chromium contents in Azadirachta indica and Phyllanthus niruri were little
more than permissible limit (2 ppm). All plants contained high amount of Fe
than permissible limit (20 ppm), set by WHO (2005). The physicochemical
properties of soils and water were within permissible limit. These results
obtained from current study are important to provide scientific data
base which will be very helpful for pharmaceutical consumption and
local practitioners using these herbs for different types of ailments.
In conclusion, monitoring such medicinal plants for heavy metals is very
useful as references for protecting the public from adverse and hazardous
effects of heavy metals.
Key words: Heavy metals, Trace elements, Medicinal plants |
