[Studies on chemical constituents from roots of Caragana sinica].

OBJECTIVE

To study the chemical constituents in roots of Caragana sinica.

METHOD

The constituents were isolated by silica gel column chromatography, and their structures were identified by spectroscopic methods.

RESULT

Seven compounds were identified as (+) - stenophyllol B (1), 4-hydroxybenzoic acid (2), odoratin (3), resveratrol (4), cararosinol A (5), leachinol C (6), carasinaurone (7) respectively.

CONCLUSION

Compound 1 was a new compound which was the enantiomer of stenophyllol B. Compounds 2-6 were obtained from the plant for the first time.
