[Studies on the aporphine alkaloids from Fissistigma oldhamii (Hemsl.) Merr].

OBJECTIVE

To study aporphine alkaloids from Fissistigma oldhamii (Hemsl.) Merr. which is a characteristic plant of Guangxi.

METHODS

Various chromatographic techniques were used to separate and purify the aporphine alkaloids. Their physical and chemical properties and spectral data were measured for structural elucidation.

RESULTS

Four aporphine alkaloids were isolated from the fraction of total alkaloids of Fissistigma oldhamii (Hemsl.) Merr. They were identified as romucosine(I), xylopine(II), O-methylmoschatolineIII), oxoxylopine(IV).

CONCLUSIONS

Compounds I is obtained from this plant for the first time.
