[Studied of Dry Matter Accumulation and Echinacoside Content of Cistanche Tubulosa in Huabei Plain].
CHINA JOURNAL OF CHINESE MATERIA MEDICA(2006)
Abstract
OBJECTIVE:To give some theory support of Cistanche tubulosa cultivation by searching dry matter accumulation and echinacoside content of C. tubulosa.METHOD: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.RESULT: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.CONCLUSION:Variation rule of dry matter accumulation and echinacoside content was found in C. tubulosa that grew one year in Huabei plain.
