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)
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)
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)
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)
The extensive prospects of polysaccharides in medicine and pharmaceuticals have elicited much interest. Ligusticum chuanxiong polysaccharides, previously extracted as neutral polysaccharides, exhibit antioxidant, anticancer, andantibacterial capacities in vitro. Here we show one pectic polysaccharide extracted from rhizome of L. chuanxiong(LCP-II-I).(More)
UNLABELLED To study the effect of S-3307 on the yield and main ingredients of Alisma plantago-aquatica. METHOD The contents of 24-acetyl alisol A and the 23-acetyl alisol B in tuber were determined by HPLC. RESULTS The contents of 24-acetyl alisol A and the 23-acetyl alisol B as well as yield were significantly increased in all groups applied with(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)
UNLABELLED To compare yield, alisol content of Alisma orientalis planted at different ecological climatic regions, and explore further the impact of environmental factors on the yield and quality. METHOD Different local varieties were planted at varing ecological climatic conditions. Diameter, yield was measured after harvest, the contents of 23-acetyl(More)
Three new minor compounds, 18-oleanene (1), lupine (2), and 12-oleanene (3) type triterpenoid saponins, along with four major known triterpenoid saponins were isolated from the buds of Lonicera macranthoides. Their structures were elucidated by spectroscopic and chemical analyses. 18-oleanene and lupine-type triterpenoid saponins were first isolated from(More)
