[Chemical constituents from root bark of Dictamnus dasycarpus].

OBJECTIVE

To isolate and identify the chemical constituents from the root bark of Dictamnus dasycarpus.

METHODS

Silica gel, Sephadex LH-20, ODS and PTLC were employed for the isolation and purification of chemical constituents. The structures were identified on the basis of spectral data and physicochemical examination.

RESULTS

Thirteen compounds were isolated and identified as follows: rutaevin (1), obacunone (2), fraxinellone (3), limonin (4), dictamnine (5), beta-sitosterol (6), 5-hydroxylmethylfuraldehyde (7), daucosterol (8), 3beta-hydroxy-cholesta-5-ene (9), fraxinellonone (10), rutin (11), quercetin (12) and scopoletin (13).

CONCLUSIONS

Compounds 7 and 9 are isolated from this genus for the first time.
