Their structures were elucidated mainly by spectroscopic methods. Among them, 1 and 4 are new isolated compounds. The cyano- and nitro-containing compounds are very rare in plants and their isolation from one traditional Chinese medicine is really interesting.展开更多

As a perennial herbaceousplant, both the aerial parts and the roots are used in traditional Chinese medicine for differentmedications. The roots are often used to treat inflammation, snake bite, bruises and injuries,tonsillitis, mastitis, scrofula, and cancer for their antibacterial, anti-inflammatory, andantineoplastic activities. The aerial parts are used for the treatment of mastitis, bruises, andheart diseases, such as endomyocarditis. The medicinal usage of this plant prompted us toinvestigate its chemical constituents. As a result, nine compounds 1-9 ( see Figure 1) were isolatedfrom the roots of S. adoxoides. Among them, compounds 1-7 and 9 were isolated from the genusSemiaquilegia for the first time.展开更多

To find more cyano-containing compounds in the important plant Semiaquilegia adoxoides （DC） Makino （Chinese name Tiankuizi）, the isolation of the chemical constituents was investigated for advancing the research. Two new compounds, a new alkaloid, 1,2,3,4-tetrahydro-6-hydroxy-1[（3,4-dihydroxyphenyl）methyl]-7-methoxy-2,2-dimethyl-isoquinolinium, named Semiaquilegine A （1）, and a new ester, 3-（4＇-hydroxyphenyl）-2-propenoic acid （4＂-carboxyl）-phenyl ester （2）, and four cyano-containing compounds, （Z）-6a-（β-D-glucosyloxy）-4a,5a-dihydroxy-2-cyclohexene-△^1,a-acetonitrile （3）, （L0-6α-（β-D-glucosyloxy）-4α-hydroxy-2-cyclohexene-△^1,α-acetonitrile （4）, lithospermoside （5）, ehretioside B （6）, as well as eleven known compounds, were isolated from the roots of Semiaquilegia adoxoides. The structures of new compounds 1 and 2 were elucidated mainly by 1D/2D-NMR techniques. Very unusual cyano-containing compounds 3 and 4 were first isolated from Ranunculaceae family. Hitherto, there were six cyano-containing compounds found in the herb.展开更多

Methods Kromasil C18 column was used with a mobile phase of methanol-water （ containing 0. 01% trifluoroacetic acid and 0. 05 % tetrahydrofuran） （3：97）. The detecting wavelength was 260 nm. Results The calibration curve was linear over the range of 0. 004 - 0. 4 mg·mL^-1 with the correlation coefficient of 1.00 000. The average recovery was 98. 77 % with RSD 2. 77 %. Determinations of ten samples from different areas showed that the contents of griffonilide in the roots of S. adoxoides are 0. 17 -0. 49 mg·g^-1. Conclusion The method provides an accurate and sensitive way to detect griffonilide in the roots of S. adoxoides .展开更多
