Pharmacological evaluation of Tectona grandis

The effect of root extracts (methanol and water) of Tectona grandis Linn. f. (Verbenaceae) on tussive was evaluated in an experimental Animal model. Treatment with aqueous extract and methanol extract 500 mg/kg p.o. dose level showed more effect on tussive as compared with the dose level of 250mg/kg p.o. Differences between means were assessed by one way analysis of variance (ANOVA), followed by Dunnett''s test using sigma stat software. Both the extracts (methanol and water) significantly (P<0.05) suppressed the asthmas at the dose level of 500mg/kg. Phytochemical tests showed that methanol and water extracts tested, positive for carbohydrates, reducing sugars, alkaloids, glycosides, flavonoids, sterols and saponins. I addition to that review literature on tectona will be very helpful for readers and for further researh.
