[Preliminary study on variation pattern of Cistanche deserticola].
OBJECTIVE
Through analyze of shape, structure and content of effective components of Cistanche deserticola, the variation of "you cong rong" is discussed.


METHODS
The color surface, texture, the size of pith and the arrange of vascular bundle was observed with freshed, dried drugs and the transverse section, the effective component of echinacoside and acteoside was analyzed with hplc and the amylose was analyzed with ultraviolet spectrophotometry.


RESULTS
The variation of "you cong rong" is obvious different with the common drug in shape and structure, the content of echinacoside is 2.5 times, acteoside is 3.8 times, amylose yield is 1.6 times and the content is 2 times of the common drugs.


CONCLUSIONS
"you cong rong" is an independent variation pattern of C. deserticola, it has no relationship with the ecological and geographical conditions.
