한국산(韓國産) 생약자원(生藥資源) 개발연구(開發硏究) (제2보)(第2報) -Prunus tomentosa의 약효성분에 관하여-

HPLC is a useful method for identifying amygdalin which has been the subject of considering controversy for cancer remedy. The resolution of amygalin was satisfactory and the separation of amygdalin was accomplished using carbohydrate analysis column, mobile phase of acetonitrile: $H_2O$ (90:10), and UV detector. Quantitative analysis showed that amygdalin contents of Prunus tomentosa, P. serrulata, and P. ishidoyana (Amygdalaceae) were 2.18, 2.41, and 2.26%, respectively. It was suggested that the seed of Prunus species was worth useful resource of amygdalin.
