The propolis was collected from the whole part of Korea Peninsula, such as central, southern, and Jeju island, to analyze the general composition including total flavonoid and phenolic contents, heavy metals,colors, amino acids, and crude lipid. The total flavonoid and phenolic contents of middle region in Korea Peninsula (4.26% and 13.06 g/100 g gallic acid)were higher than southern region (2.53%, 10.9 g/100 g gallic acid) and Jeju island (0.03%, 7.22g/100 g gallic acid), respectively. The heavy metals contents showed that Zn contents were found in 0.44±0.2 ppm and a harmful heavy metal such as Cr, Cd, Pb, Ni, Cu, As,and Hg were not detected at all in our experiment. The colors of extracted propolis showed a various spectrum from yellow to red purple. Various amino acids were also detected as proline, valine, methionine and the average crude lipid contents of propolis were 42.4%. All data collected in South Korea were very first executed in our institution for the purposes of utilizing and developing the industrial insects, honeybees as well as silkworm.
