The plant Trewia nudiflora is locally known as Lattu, Latim, Laddu tree in Bangladesh and has many reported pharmacological activities. The aqueous crude extract (decoction) is popularly used for the household treatment. In the present study, the extraction efficiency of the decoction method was compared to the conventional ethanolic extraction by quantitative and qualitative phytochemical analysis by using leaves and barks of T. nudiflora. Both fresh and dried parts of the plants were used for decoction to justify the importance of following the time-consuming drying process of plant materials traditionally practiced before any extraction. Though better extraction yield was observed in ethanolic extraction the presence of phytochemicals were almost similar to the decoction from dried leaves and barks. Whereas though the similar yield extraction were observed in decoction both from fresh and dried leaves and barks, comparatively less phytochemicals were present in the decoction obtained from fresh plant’s parts. However, considering the extraction yields and the presence of phytochemicals proved the ethanolic extraction better than the decoction methods. Unfortunately crude extract obtained by decoction and ethanol from fresh and dried leaves and barks failed to show favorable antimicrobial activities E. coli made question marks on the pharmacological properties of that plant. However, further studies are required for getting a decision regarding antimicrobial properties of the plants.
