[Abstract]To study the anti-tumor metastatic constituents in Rhodiola wallichiana (HK) S H Fu var Cholaensis (Praeg) S H Fu, chemical constituents were isolated and purified by repeated column chromatography(silica gel, Toyopearl HW-40C and preparative HPLC). Their structures were elucidated on the basis of spectral data analysis. The anti-tumor metastasis assay was applied to evaluate the activities of the isolated compounds. Ten compounds(1-10) were isolated and their structures were identified by comparison of their spectral data with literature as follows: syringic acid(1), salidroside(2), tyrosol(3), scaphopetalone(4), berchemol(5), 2,6-dimethoxyacetophenone(6), rhobupcyanoside A(7), miyaginin(8), chavicol-4-O-β-D-apiofuranosyl-(1→6)-O-β-D-glucopyranoside(9), eugenyol- O-β-D-apiofuranosyl-(1→6)-O-β-D-glucopyranoside(10). Compounds 4-6 and 8-10, were isolated from this genus  for the first time, while compound 7 was isolated from this plant for the first time. Compounds 2, 6-8 showed positive anti-tumor metastatic activities, and compounds 2 and 8 showed significant anti-tumor metastatic activities.
