[Studies on chemical constituents from herb of Dracocephalum moldavica].

OBJECTIVE

To study the chemical constituents from the whole plant of Dracocephalum moldavica.

METHOD

The compounds were isolated by using column chromatography with RA polystyrene resin, polyamide and silica gel as packing materials, and the structures of the compounds were identified by means of spectral data.

RESULT

eight compounds were identified as apigenin(I), luteolin(II), kaempferol(III), isorhamnetin(IV), tilianin(V), agastachoside(VI), acacetin-7-O-(6-O-Malonyl-beta-D-glucopyranoside) (VII) and syringaresinol(VIII).

CONCLUSION

Compounds I, II and III were isolated from genus Dracocephalum for the first time and compounds IV, VII and VIII were isolated from Dracocephalum moldavuca for the first time.
