Two pectic polysaccharides, 50 WCP-II-I and 100 WCP-II-I, were obtained from 50 and 100 °C water extracts of Codonopsis pilosula roots by ion exchange chromatography and gel filtration. The study of the sub-fractions obtained after pectinase degradation showed that the complement fixation activities of these pectins are expressed mainly by their ramified(More)
Two new secoiridoid glycosides, named ethyl secologanoside (1) and 6'-O-alpha-L-arabinopyranosyl demethylsecologanol (2), together with three known ones, secologanoside (3), secoxyloganin (4), and loniceroside (5), were isolated from the dried buds of Lonicera macranthoides. The structures of the new compounds were determined on the basis of detailed(More)
In order to select high quality and suitable Bupleuri Radix varieties in Qingchuan, and establish a new comprehensive method to evaluation the quality of Bupleuri Radix, 12 characters of 14 samples were evaluated by DTOPSIS and grey related degree. The results showed that varieties No. 8 and No. 10 had high quality. DTOPSIS and grey related degree gave the(More)
The chromatographic fingerprint was established for evaluating and controlling the quality of germplasm resource of Ophiopogon japonicus in Sichuan Basin by reversed-phase high performance liquid chromatography and gas chromatography mass spectrometry. The results showed that each sample the characterized by the peak area of 28 HPLC peaks and 13 GC peaks in(More)
OBJECTIVE To study the absorption and accumulation of N, P and K in Ophiopgon japonicus. METHOD The contents of N, P, K and trace element were determined respectively by using the kjeldathl method digested with H2SO4 + H2O2, ammonium vanadstemolybdate chromoscopy, flame spectrometry and atomic absorption spectrophotometry. RESULT The contents of N and K(More)
OBJECTIVE To study the effects of Fe, Zn, B and Mn fertilizer with different ratio on the yield and quality of Aconitum carmichaeli. METHOD Field experiment with the uniform design was applied, the yield and the contents of the total alkaloids and diester-alkaloids were measured. RESULT Fe, Zn, B and Mn fertilizer of appropriate ratio could promote the(More)
OBJECTIVE To study the effects of different N, P, K and organic fertilizer (OF) on yield of Ligusticum chuanxiong rhizome, in order to provide the theoretical foundation for the establishment of standardization cultivation techniques. METHODS The field plot experiments used Ligusticum chuanxiong rhizome which planted in Pengshan as material, and were(More)
Seeds of Bupleurum chinense cultivar, Zhongchai No. 1, were sowed in plastic pots which used the arable layer soil as the nursery bed and putted in the artificial climate incubator at various temperatures (15, 20, 25, 15-25 degrees C) and light (8,12 h) to germinate, respectively. The lower constant temperature (15 degrees ) and the higher constant(More)
As a comprehensive, quantifiable identification method based on the chemical composition information of traditional Chinese medicine (TCM), the fingerprint of traditional Chinese medicine has become an internationally recognized effective way to control the quality of natural medicine. Chemical pattern recognition in traditional Chinese medicines is an(More)
OBJECTIVE To compare the agronomic characters, HPLC fingerprints, the content of main component and amino acid between erective and creepy Ophiopogon japonicus of Sichuan. METHOD Agronomic characters were measured by conventional methods; HPLC was applied on a C18 column with CH3OH-CH3CN-2% CH2COOH solution by gradient elution, quercetin was used as the(More)
