Iridoid glycosides were the main active ingredient of Rehmannia glutinosa, of which catalpol has the highest content. This work will provide theoretical basis for metabolic study and cultivation of iridoids on the basis of the dynamic accumulation of catalpol and total iridoids in the growth of R. glutinosa. The samples of rehmannia 85-5 were gathered in(More)
OBJECTIVE To evaluate the germplasm of Rehmannia glutinosa on the basis of photosynthetic pigment contents (PPC). METHOD 20 cultivars were planted on the same condition. On Oct. 23 and Sept. 25, 3 leaves per cultivar were collected on different plants, and 80 mg mesophyll was collected among upper lateral veins and was ground in 96% alcohol, and the(More)
OBJECTIVE To sift the main effective factors of active component of Forsythia suspense. METHOD The active component of F. suspense was mensurated by HPLC, and the contents of nutrition in soil was determined by conventional methods. The active component of F. suspense and the nutrition of soil collected from different regions was analyzed by SPSS 11.0 for(More)
OBJECTIVE To control the seed quality market, a study on the seed determination practice in Polygala tenuifolia was carried out. METHOD By studying the thousand grain weight moisture content, viability, genuineness, purity and germination percentage, some indices of seeds were fixed to the standards. The seed determination practice in P. tenuifolia was(More)
Zhejiang and Sichuan are regarded as two genuine producing areas of Ophiopogonis radix in China. To study the difference in the quality of Ophiopogonis radix from these two places, the contents of three reported bioactive saponins, that is, ophiopogonins B, D, and D', in tubers and fibrous roots of Ophiopogon japonicus from Cixi city of Zhejiang and Santai(More)
OBJECTIVE To study on diversity of quality of Forsythia suspense collected from different regions. METHOD The hundred-seed weight of shucks was analyzed by the method of hundred grain mass. The thousand-seed weight of seeds was analyzed by the method of thousand grain mass. The contents of the active components in shucks and seeds were determined by HPLC.(More)
OBJECTIVE To compare difference in character between wild germplasm and cultivar of Rehmannia glutinosa Libosch. METHOD Field test and statistical analysis were applied. RESULT The results showed that the plant height and leave weight of individual plant in cultivar were decreased significantly comparing to wild germplasm, and the output was increased(More)
OBJECTIVE To analyze the genetic diversity of wild Rehmannia glutinosa and evaluate and compare random amplified polymorphic DNA (RAPD) and inter sample sequence repeat (ISSR) for analysis of R. glutinosa accessions. METHOD Two molecular markers, RAPD and ISSR were used for analyzing 55 wild R. glutinosa accessions. RESULT Average 16.00 and 19.08 bands(More)
OBJECTIVE To establish a seed testing methods for Salvia miltiorrhiza. METHOD Referring to the International Seed Testing Rules made by ISTA and the Seed Testing for Crops (GB/T3543. 1-1995) issued by China. RESULT The seeds are selected by winnowing; the seed purity is about 50%-60%; 100 grain weight is used to determine the quality of the seed; the(More)
OBJECTIVE To study the dominant seed-borne fungi of Glycyrrihiza seeds which were from different producing area and compare the disinfection effect of several fungicides on seed-borne fungi of Glycyrrihiza seed. METHOD Petri-dish testing was used to determine the external and internal seed-borne fungi and the disinfection effect of fungicides. RESULT(More)
