It could give some theory support of confirming the secondary metabolism organ and regulation of echinacoside in Cistanche tubulosa by searching parasitic growth of C. tubulosa ahd echinacoside variation in different organs of host and parasite.The echinacoside content was analyzed by HPLC. The relationship between dry matter accumulation and echinacoside accumulation of C. tubulosa as the well as root diameter of host were comparatively analyzed.With the increase of dry matter accumulation of C. tubulosa, echinacoside accumulation increased significantly, and both of them were in significantly positive correlated with the root diameter of host. Echinacoside content in haustorium phloem was 15.53%, higher than that of haustorium xylem, C. tubulosa plant and other organs.Haustorium phloem was probably the secondary metabolism organ of echinacoside in C. tubulosa.
