1Chengdu Institute of Biology, Chinese Academy of Sciences, Chengdu 610041, China.
Aim:
To investigate the chemical constituents from the roots of Diuranthera inarticulata Wang et K. Y. Lang.
Methods:
The compounds were isolated with silica gel column chromatography and their structures were identified on the basis of spectral data and TLC with authentic samples.
Results:
From the methanolic extracts of the roots of Diuranthera inarticulata, ten compounds were obtained and nine of them were identified as chloromaloside A (III), diuranthoside A (IV), diuranthoside B (V), diuranthoside F (VI), diuranthoside G (VII), 2 alpha, 3 alpha, 19 alpha-trihydroxy-urs-12-en-28-oic acid (VIII), 3,6,7,3',4'-pentamethoxy flavone (IX), gitogenin (X) and daucosterol (XI). III-VI showed inhibition of growth with the yeast, Candida albicans. III, IV and VI also showed inhibition of growth with fungus, Aspergillus niger, in the test of antibacterial activity.
Conclusion:
All of these compounds were isolated from this plant for the first time. Among them, VI and VII are new steroidal saponins.

Conformation
The simplest example of a diene is 1,3-butadiene, an acyclic conjugated π system. At room temperature, the molecule exists as a mixture of s-cis and s-trans conformers by virtue of rotation around the carbon–carbon single bond. Although the s-trans isomer is more stable, the...
