title: Identification of the plant origin of propolis from Jeju Island, Korea, by observation of honeybee behavior and phytochemical analysis.
abstract: Propolis collected on Jeju Island, Korea, contains characteristic components not present in propolis from other regions. Hence, the plant origin of the propolis from Jeju Island can be expected to be a novel plant. To identify the plant origin of this propolis, first we observed honeybee behavior, and found them collecting the resin from Angelica keiskei. Then comparative analyses of chemical and biological properties of the resin from the plant and propolis from hives of nearby apiaries were performed. Alcoholic extracts showed entirely identical HPLC profiles and closely similar antioxidant activities. These results indicate that A. keiskei is the plant origin of the propolis from Jeju Island, Korea.
