Context: This study is aimed to analyse heavy metal content and antioxidant potential of three types of Jamun honey samples from Western Ghats of India. Ash, pH, and colour intensity were anlyased. Heavy metal analysis for Arsenic (As), Lead (Pb), chromium (Cr) and Mercury (Hg) were carried out using inductively coupled plasma - optical emission spectrometry (ICP-OES). Total polyphenol (TPC), total flavonoid content (TFC) and antioxidant assays such as 2, 2-diphenyl-1-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP) were performed. Comparative studies of Jamun honeys revealed strong correlation between TPC and TFC as significant radical scavenging activities. Colour values represented strong correlation with TPC and TFC at (r= 0.9) and FRAP at (r= 0.8) whereas a negative correlation with IC 50 values of DPPH at (r= -0.6) was observed.
