Phytother Res. 2002 May;16(3):281-2. | Spasmolytic activity of Toddalia asiatica Var. floribunda.[Pubmed: 12164278] | METHODS AND RESULTS: The spasmolytic activity of the aerial parts of Toddalia asiatica var. floribunda (family Rutaceae) was evaluated. The ethanol extract exhibited significant spasmolytic activity and was then partitioned into five fractions. The activity was found to be concentrated only in the hexane and chloroform fractions.
CONCLUSIONS:
This activity was shown not to be due to the coumarins, toddalolactone and toddanone, as was previously thought. | Huria Journal of the Open University of Tanzania, 2012 , 12 (1). | Antifeedant activity of twenty six plant extracts and pure compounds from the root bark of Toddalia asiatica (L) (Rutaceae) against the anomalous emperor moth Nudaurelia belina (Saturnidae)[Reference: WebLink] | The antifeedant activity of petroleum ether (PE) (40-60%) extract of the root bark of T. asiatica and twenty five other plant extracts was investigated against the anomalous emperor moth N. belina.
METHODS AND RESULTS:
The petroleum ether extract of stem bark of Albizia anthelmintica, leaves of Cassia occidentalis, Balanites aegyptica, seeds of Cucumis sativaus, root bark of T. asiatica, root bark of Celtis durandii, B. aegyptica and whole plant of Cisus quadrangularis were found to be active against N. belina at a concentration of 1% w/v in a modified leaf disc method. Also, methanol extracts of the root bark of A. muricata and Eucalyptus spp were found to be active against N. belina at a concentration of 1% w/v.
CONCLUSIONS:
Three cumarius; dihydrotoddanol, toddanol and toddalactone and the alkaloid dihydrochelerynthrine isolated from the PE extract of the root bark of T. asiatica exhibited antifeedant activity at as low as 0.05% w/v. Toddaculine and Toddanone which were also isolated from the P.E. extract had no activity at 0.05% w/v. |
