The purpose of this research is to provide basic informations to discriminate between sea buckthorn (Hippophae rhamnoides) cultivated in the Republic of Korea and Mongolia. The phenolic compounds of sea buckthorn, were measured by the HPLC analysis. Catechin, rutin, quercetin, isorhamnetin were found in methanol extracts of sea buckthorn. Total phenolic compound of Korean sea buckthorn leaves (1.852%) was about five times higher than those of Mongolian sea buckthorn berries (0.338%). As a result, the order of the total phenolic compound and Catechin content was 1) sea buckthorn leaves, 2) sea buckthorn stems, 3) sea buckthorn roots, and 4) sea buckthorn berries. Statistically no big differences in levels of phenolic compounds were consistently found in sea buckthorn cultivated in the Republic of Korea and Mongolia investigated in this work.
