[Studied of dry matter accumulation and echinacoside content of Cistanche tubulosa in Huabei plain].
OBJECTIVE
To give some theory support of Cistanche tubulosa cultivation by searching dry matter accumulation and echinacoside content of C. tubulosa.


METHODS
Dry matter accumulation content of C. tubulosa culturing in Huabei plain was analysed in different growth season of C. tubulosa. Echinacoside content was determined by HPLC.


RESULTS
Dry matter accumulation of C. tubulosa showed "S" variation. Dry matter accumulation increased fastest in September among growing seasons. Dry matter amount was 138.58 g after C. tubulosa grew a year. Dry matter amount decreased significantly along with inoculation time retarded. Echinacoside content was 30.59% when C. tubulosa grew in 5 months, decreased guadully after that, and 9.76% in annual.


CONCLUSIONS
Variation rule of dry matter accumulation and echinacoside content was found in C. tubulosa that grew one year in Huabei plain.
