ABSTRACT:   Medicinal plants are the most important source of life saving drugs for the majority of the world population. World Health Organization (WHO) 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 determine the heavy metals contamination in Tinospora cordifolia (ဆင်တုံးမနွယ်ပြောင်ချော) and Tinospora crispa (ဆင်တုံး မနွယ်ဆူးပေါက်), which are reputed to have antidiabetic, antiinflammatory, antiarthritic, antispasmodic and antiallergic activities. The atomic absorption spectrophotometer (AAS) was used for determination of heavy metals (Cd, Cr, Cu, Fe, Pb and Zn) in two Tinospora species and their surrounding soils from Mandalay, Pyin Oo Lwin and Shwe Bo. These two Tinospora species contained metals (Cd, Cr, Cu, Pb and Zn), which were within permissible limits except Fe content more than (20 ppm), set by WHO, 2005. All soils contained metals which were within permissible limits. These findings obtained from present study will be helpful for herbal medicine users, local practitioners and pharmaceutical industries using these two Tinospora species for different types of ailments. In conclusion, monitoring such medicinal plants for heavy metals is important in protecting the public from adverse and hazardous effects of heavy metals.
